1. Introduction
1.1. Overview
The SMC2585W-G is a versatile device that can be configured to be in one of the 3 operational modes—Bridge Repeater, AP Repeater, Dual AP—for various wireless bridging applications. With the convenient Web-based user interface, a network administrator can easily
and clearly manage the SMC2585W-G.
1.2. Features
IEEE 802.11b/g Compliant
„
Operational modes.
Bridge Repeater. In this mode, both WLAN interfaces are configured as
LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between
two wireless LAN-to-LAN bridges.
Static AP Repeater. In this mode, one WLAN interface is configured as an
AP interface, and the other is configured as a LAN-to-LAN bridge interface.
Dynamic AP Repeater. In this mode, one WLAN interface is configured as
an AP interface, and the other is configured as an AP client-based dynamic
bridge Interface.
Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces.
The dual AP can handle twice the number of wireless clients than a normal
AP.
„
64-bit and 128-bit WEP (Wired Equivalent Privacy). For wireless data encryption.
„
IEEE 802.1x/RADIUS. When the SMC2585W-G is in Access Point mode, it can be
configured to authenticate wireless users and distribute encryption keys dynamically by IEEE 802.1x Port-Based Network Access Control and RADIUS (Remote
Authentication Dial-In User Service).
„
WPA (Wi-Fi Protected Access). The SMC2585W-G supports the new WPA
standard. Both WPA-PSK (Pre-Shared Key) mode and full WPA mode are supported. WPA is composed of TKIP (Temporal Key Integrity Protocol) and IEEE
802.1x and serves as a successor to WEP for better WLAN security.
„
Enabling/disabling SSID broadcasts. When the SMC2585W-G is in AP mode,
the administrator can enable or disable the SSID broadcasts functionality for security reasons. When the SSID broadcasts functionality is disabled, an STA cannot
associate with the AP with an ANY network name (SSID, Service Set ID); the correct SSID has to be specified on the STA.
„
MAC-address-based access control. When the SMC2585W-G is in AP mode, it
can be configured to block unauthorized STAs based on MAC (Media Access
Control) addresses. The ACL (Access Control List) can also be downloaded from a
TFTP server.
„
Transmit power control. Transmit power of the SMC2585W-G can be adjusted to
control the area of coverage.
„
Wireless client isolation. When the SMC2585W-G is in AP mode, wireless-to-wireless traffic between STAs can be blocked so that the STAs cannot see
each other. This capability can be used in hotspots applications to prevent wireless
hackers from attacking other wireless users’ computers.
„
Link integrity. When the SMC2585W-G is in AP mode and the Ethernet LAN interface is detected to be disconnected from the wired network, all currently associated wireless clients are disassociated by the SMC2585W-G and no wireless client
can associate with it thereafter.
„
Associated wireless clients status. Showing the status of all wireless clients that
are associated with the SMC2585W-G.
„
Detachable antenna. The SMC2585W-G antenna can be replaced with SMC
high-gain antennas for long operating range.
DHCP client. The SMC2585W-G can automatically obtain an IP address from a DHCP
server.
DHCP server. The SMC2585W-G can automatically assign IP addresses to computers
or other devices by DHCP (Dynamic Host Configuration Protocol).
„
Static DHCP mappings. The administrator can specify static IP address to MAC
address mappings so that the specified IP addresses are always assigned to the
hosts with the specified MAC addresses.
„
Current DHCP mappings. Showing which IP address is assigned to which host
identified by a MAC address.
Packet Filtering. The SMC2585W-G provides Layer 2, Layer 3, and Layer 4 filtering
capabilities.
Firmware Tools
„

SMC2585W-G for management purposes at a time.
„
SNMP. SNMP (Simple Network Management Protocol) MIB I, MIB II, IEEE 802.1d,
and Private Enterprise MIB are supported.
„
UPnP. The SMC2585W-G responds to UPnP discovery messages so that a Windows XP user can locate the SMC2585W-G in My Network Places and use a Web
browser to configure it.
„
Telnet. The SMC2585W-G can be managed by Telnet.
„
System log. For system operational status monitoring.
‹
Local log. System events are logged to the on-board RAM of the
SMC2585W-G and can be viewed using a Web browser.
‹
Remote log by SNMP trap. Systems events are sent in the form of SNMP
traps to a remote SNMP management server.
‹
Remote log by BSD Syslog. Systems events are sent in the form of BSD
Syslog (RFC3164) to a remote Syslog server.
Power over Ethernet. Supplying power to an SMC2585W-G over an Ethernet cable
using optional SMCPWR-INJ3 Power Injector (IEEE 802.3af compliant). This feature
facilitates large-scale wireless LAN deployment.

Fig. 3. Mounting the SMC2585W-G on a wall.
2.3. Preparing for Configuration
To configure a SMC2585W-G, a managing computer with a Web browser is needed. For
first-time configuration of a SMC2585W-G, an Ethernet network interface card (NIC) should
have been installed in the managing computer. For maintenance-configuration of a deployed
SMC2585W-G, either a wireless computer or a wired computer can be employed as the
managing computer.
NOTE: If you are using the browser, Opera, to configure an SMC2585W-G, click the menu
item File, click Preferences... click File types, and edit the MIME type, text/html, to add a
file extension “.sht” so that Opera can work properly with the Web management pages of the
SMC2585W-G.
Since the configuration/management protocol is HTTP-based, you have to make sure that
the IP address of the managing computer and the IP address of the managed
SMC2585W-G are in the same IP subnet (Default IP address is set to DHCP client, it will
default to 192.168.2.50 if there is no DHCP server present.)
2.3.1. Connecting the Managing Computer and the
SMC2585W-G
To connect the managing computer and the SMC2585W-G for first-time configuration, you
have two choices as illustrated in Fig. 4.

You can use either a cross-over Ethernet cable (included in the package) or a switch/hub
with 2 straight-through Ethernet cables.
NOTE: One connector of the Ethernet cable must be plugged into the LAN Ethernet port of
the SMC2585W-G for configuration.
2.3.2. Changing the TCP/IP Settings of the Managing
Computer
Use the Windows Network Control Panel Applet to change the TCP/IP settings of the
managing computer, so that the IP address of the computer and the IP address of the
SMC2585W-G are in the same IP subnet. Set the IP address of the computer to
192.168.2.xxx (Default IP address is set to DHCP client, it will default to 192.168.2.50 if
there is no DHCP server present.)
TIP: You can use SMC2585W-G Scan Utility on the CD-ROM to scan for all the
SMC2585W-Gs on the network. Double-click a scanned SMC2585W-G to launch the Web
browser to manage the SMC2585W-G. Note that this utility does not discover the
SMC2682W.
NOTE: On Windows 2000/XP, SMC2585W-G Scan Utility can only be run by a user with
administrator privilege.
NOTE: For some versions of Windows, the computer needs to be restarted for the changes
of TCP/IP settings to take effect.
2.4. Configuring the SMC2585W-G
The SMC2585W-G is DHCP client enabled by default. After the IP addressing is configured,
launch a Web browser on the managing computer. Then, go to “http://192.168.2.50” to log
on to the SMC2585W-G for Web-based management.
TIP: For maintenance configuration of an SMC2585W-G, the SMC2585W-G can be reached
by its host name using a Web browser. For example, if the SMC2585W-G is named “AP”,
you can use the URL “http://AP” to access the Web-based management interface of the
SMC2585W-G.
2.4.1. Entering the User Name and Password

can be saved or printed within the Web browser for future reference.
Fig. 6. The Status page.
2.4.2. Step 1: Selecting an Operational Mode
Fig. 7. Operational modes settings.
The SMC2585W-G supports 3 operational modes for meeting various wireless connectivity
requirements:
‹
Bridge Repeater. In this mode, both WLAN interfaces are configured as
LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between
two wireless LAN-to-LAN bridges.
‹
Static AP Repeater. In this mode, one WLAN interface is configured as an
AP interface, and the other is configured as a LAN-to-LAN bridge interface.
‹
Dynamic AP Repeater. In this mode, one WLAN interface is configured as
an AP interface, and the other is configured as an AP client-based dynamic
bridge Interface.
‹
Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces.
The dual AP can handle twice the number of wireless clients than a normal
AP.
In any mode, the SMC2585W-G forwards packets between its Ethernet interface and
wireless interface for wired hosts on the Ethernet side and wireless host(s) on the wireless side.
There is 1 type of wireless link to bridge between other SMC2585W-G or SMC2586W-G,
and SMC2582W-B bridges.
„
WDS. This type of wireless link is specified in the IEEE 802.11 standard for communication between two IEEE 802.11 APs. Wireless packets transmitted along the
WDS link comply with the IEEE 802.11 WDS (Wireless Distribution System) format
at the link layer.
10
2.4.3. Step 2: Configuring TCP/IP Settings
Fig. 8. TCP/IP settings.
Go to the TCP/IP Addressing section to configure IP address settings. The IP address can
be manually set or automatically assigned by a DHCP server on the LAN (Default: DHCP
client enabled). If you are manually setting the IP address, Subnet mask, and Default
gateway settings, set them appropriately, so that they comply with your LAN environment. In
addition, you can specify the Host name and Domain (DNS suffix) of the SMC2585W-G.
When you are finished, click Save at the bottom of this page, and then you are brought back
to the start page.
Step 3: Configuring IEEE 802.11 Settings
Fig. 9. IEEE 802.11g communication settings.
Go to the IEEE 802.11, Communication section to configure IEEE 802.11g-related communication settings, including Channel number and Network name (SSID).
The number of available RF channels depends on local regulations.
11
NOTE: The Regulatory domain setting of the SMC2585W-G sold in the U.S. and Canada
in not configurable. It’s set to FCC by default. As a result, only channels from 1 to 11 are
available.
NOTE: For two SMC2585W-Gs or one wireless client computer and one SMC2585W-G to
establish a wireless link, both devices must be configured with the same channel number
and SSID.
Fig. 10. Wireless Distribution System settings.
To enable a WDS link:
1.
Specify the MAC address of the AP or bridge at the other end of the WDS link.
2.
Select the corresponding Enabled check box.
For example, assume you want two SMC2585W-Gs with MAC addresses
00-02-65-01-62-C5 and 00-02-65-01-62-C6 to establish a WDS link between them. On
SMC2585W-G 00-02-65-01-62-C5, set the peer MAC address of port 1 to
00-02-65-01-62-C6 and on SMC2585W-G 00-02-65-01-62-C6, set the peer MAC address of
port 1 to 00-02-65-01-C5.
3. When you are finished, click Save at the bottom of this page. You will be brought back to
the Status page.
TIP: Plan your wireless network and draw a diagram, so that you know how the
SMC2585W-G is connected to other peer APs or wireless bridges by WDS.
12
Fig. 11. Sample wireless bridge network topology.
WARNING: Do not let your network topology consist of wireless bridges, Ethernet switches,
Ethernet links, and WDS links that form a loop. If there are any loops that exist, packets will
circle around the loops and network performance will be seriously degraded.
Fig. 12. Network topology containing a loop.
13
2.4.4. Step 4: Reviewing and Applying Settings
Fig. 13. Settings changes are highlighted in red.
On the start page, you can review all the settings you have made. Changes are highlighted
in red. If they are OK, click Restart for the new settings to take effect.
NOTE: It takes about 7 seconds for the SMC2585W-G to complete its restart process.
NOTE: If you decide not to change settings of the SMC2585W-G, be sure to log off by clicking the Log Off button on the left menu. This way another administrator can log on to the
device to do configuration and management. If you do not click the Log Off button or have
not interacted with the Web management interface for a period of time specified by the Web
admin idle timeout setting (5 minutes by default), you’ll be automatically logged off by the
device.
2.5. Deploying the SMC2585W-G
After the settings have been configured, deploy the SMC2585W-G to the field application
environment. Connect the SMC2585W-G to an Ethernet LAN through an Ethernet
switch/hub.
If external high-gain directional antennas are needed, it may be difficult to align the antennas.
Here are some suggestions for antenna alignment.
To adjust the alignments of a pair of SMC high-gain antennas:
1.
Connect each SMC2585W-G to a computer via Ethernet.
2.
Configure the date rate of each SMC2585W-G to the lowest value, 1Mbps.
14
3.
Fix the alignment of the antenna on one side.
4.
Adjust the alignment of the antenna on other side by using response time information
obtained from PINGing (run PING.exe) the “fixed-side” computer.
5.
Fine-tune the alignment of the antenna until you get the best response time.
6.
Increase the data rate of each SMC2585W-G simultaneously until an optimal workable
data rate is reached. You may not be able to use the highest data rate, 54Mbps, because of the distance and the gain of the antennas.
Fig. 14 illustrates the idea.

19
3.3. General Operations
3.3.1. Selecting an Operational Mode
Fig. 22. Operational modes settings.
The SMC2585W-G supports 4 operational modes for meeting various wireless connectivity
requirements:
‹
Bridge Repeater. In this mode, both WLAN interfaces are configured as
LAN-to-LAN bridge interfaces. A bridge repeater forwards packets between
two wireless LAN-to-LAN bridges.
‹
Static AP Repeater. In this mode, one WLAN interface is configured as an
AP interface, and the other is configured as a LAN-to-LAN bridge interface.
‹
Dynamic AP Repeater. In this mode, one WLAN interface is configured as
an AP interface, and the other is configured as an AP client-based dynamic
bridge Interface.
‹
Dual AP. In this mode, both WLAN interfaces are configured as AP interfaces.
The dual AP can handle twice the number of wireless clients than a normal
AP.
In any mode, the SMC2585W-G forwards packets between its Ethernet interface and wireless interface for wired hosts on the Ethernet side and wireless host(s) on the wireless side.
There are 2 types of wireless links between two SMC2585W-Gs or between an
20
SMC2585W-G and another wireless device.
„
STA-AP. This type of wireless link is specified in the IEEE 802.11 standard for
communication between an IEEE 802.11 Station (STA) and an IEEE 802.11 Access Point (AP). An STA is usually a client computer (PC or PDA) with a WLAN
network interface card (NIC).
„
WDS. This type of wireless link is specified in the IEEE 802.11 standard for communication between two IEEE 802.11 APs. Wireless packets transmitted along the
WDS link comply with the IEEE 802.11 WDS (Wireless Distribution System) format
at the link layer.
The relationships among the operational modes and the wireless link types are shown in the
following table:
3.3.2. Changing Password
Fig. 23. Password.

SMC2585W-G’s TFTP client to communicate with a TFTP server. If the TFTP client does not
get a response from the TFTP server within a period specified by the Timeout setting, it will
22
resend the previous request. The Max number of retries setting specifies the maximal
number of resend before the TFTP client stops communicating with the TFTP server.
The SMC2585W-G Installation CD includes a TFTP server program (TftpSrvr.exe) for firmware upgrade. Run this program on the computer which serves as a TFTP server.

3.3.3.5. Resetting Configuration to Factory Defaults
Fig. 32. Configuration reset.
Click on the Reset button to reset the device configuration to factory defaults.
3.4. Configuring TCP/IP Related Settings
3.4.1. Addressing
Fig. 33. TCP/IP settings.
The IP address of the SMC2585W-G can be manually set (Set Manually) or automatically
assigned by a DHCP server on the LAN (Obtain from a DHCP Server – enabled by default). If you are manually setting the IP address, Subnet mask, and Default gateway settings, set them appropriately, so that they comply with your LAN environment. In addition,
you can specify the Host name and Domain (DNS suffix) of the SMC2585W-G.
26
3.4.2. DHCP Server
3.4.2.1. Basic
Fig. 34. Basic DHCP server settings.
The SMC2585W-G can automatically assign IP addresses to client computers by DHCP. In
this section of the management page, you can specify the Default gateway, Subnet mask,
Primary DNS server, and Secondary DNS server settings that will be sent to a client at its
request. Additionally, you can specify the first IP address that will be assigned to the clients
and the number of allocateable IP addresses.
NOTE: There should be only one DHCP server on the LAN; otherwise, DHCP would not
work properly. If there is a DHCP server on the LAN already, disable the DHCP server functionality of the SMC2585W-G.
NOTE: By default the DHCP server function is disabled.
3.4.2.2. Static DHCP Mappings
Fig. 35. Static DHCP mappings.
IP addresses of servers are often static so that clients could always locate the servers by the
static IP addresses. By Static DHCP Mappings, you can ensure that a host will get the
same IP address when it requests one from the DHCP server. Therefore, instead of configuring the IP address of an intranet server manually, you can configure the server to obtain
27
an IP address by DHCP and it is always assigned the same IP address.
To always assign a static IP address to a specific DHCP client:
1.
Specify the MAC address of the DHCP client and the IP address to be assigned to it.
Then, give a description of this mapping.
2.
Select the corresponding Enabled check box.
3.5. Configuring IEEE 802.11b/g-Related Settings
3.5.1. Communication
3.5.1.1. Basic
Basic IEEE 802.11b/g-related communication settings include AP functionality, Regulatory
domain, Channel number, Network name (SSID), Data rate, and Transmit power.
Fig. 36. Basic IEEE 802.11b/g communication settings.
For specific needs such as configuring the SMC2585W-G as a wireless LAN-to-LAN bridge,
the AP functionality can be disabled, so that no wireless client can associate with the
SMC2585W-G.
Since the IEEE 802.11g-based SMC2585W-G is also IEEE 802.11b compatible, you can
configure the Policy setting to meet your backwards compatibility needs. If the
SMC2585W-G is used in an environment in which all wireless clients are IEEE
802.11b-based, set Policy to b only. If all the wireless clients are IEEE 802.11g-based, set
Policy to g only. For maximal flexibility, set Policy to Mixed, in which mode, the
SMC2585W-G supports both IEEE 802.11b- and IEEE 802.11g-based wireless clients.
The number of available RF channels depends on local regulations; therefore you have to
choose an appropriate regulatory domain to comply with local regulations. The SSID of a
wireless client computer and the SSID of the SMC2585W-G must be identical for them to
communicate with each other.
NOTE: The Regulatory domain setting of the SMC2585W-G sold in the U.S. and Canada
in not configurable. It’s set to FCC by default. As a result, only channels from 1 to 11 are
available.
If there is RF interference, you may want to reduce the Data rate for more reliable wireless
transmission. In most cases, leave the setting to Auto.
28
The transmit power of the RF module of the SMC2585W-G can be adjusted so that the RF
coverage of the SMC2585W-G can be changed.
3.5.1.2. Link Integrity
Fig. 37. Link integrity settings.
When the SMC2585W-G is in AP mode and the Ethernet LAN interface is detected to be
disconnected from the wired network, all currently associated wireless clients are disassociated by the SMC2585W-G and no wireless client can associate with the SMC2585W-G. The
detection mechanism is based on pinging the IP address specified in Reference host.
3.5.1.3. Wireless Distribution System
Notebook
Computer
WDS
LAN
AP 2
AP 1
Fig. 38. Wireless Distribution System.
Traditionally, access points are connected by Ethernet. By IEEE 802.11 Wireless Distribution
System (WDS), APs can communicate with one another wirelessly. For example, in Fig. 38,
AP 2 acts as an access point for the notebook computers and it forwards packets sent from
the notebook computers to AP 1 through WDS. Then, AP 1 forwards the packets to the
Ethernet LAN. Packets destined for the notebook computers follow a reverse path from the
Ethernet LAN through the APs to the notebook computers. In this way, AP 2 plays a role of
“AP repeater”.

Bridge 2
Fig. 39. LAN-to-LAN bridging.
By WDS, two or more LAN segments can be connected wirelessly. As illustrated in Fig. 39, a
pair of wireless LAN-to-LAN bridges is used to connect two LAN segments. Since the
SMC2585W-G is WDS-enabled, it can be used as a wireless bridge even when it is in AP
mode.
NOTE: An SMC2585W-G can have up to 6 WDS links to other APs or wireless bridges per
radio.
Fig. 40. Wireless Distribution System settings.
To enable a WDS link:
3.
Specify the MAC address of the AP or bridge at the other end of the WDS link.
4.
Select the corresponding Enabled check box.
For example, assume you want two SMC2585W-Gs with MAC addresses
00-02-65-01-62-C5 and 00-02-65-01-62-C6 to establish a WDS link between them. On
SMC2585W-G 00-02-65-01-62-C5, set the peer MAC address of port 1 to
00-02-65-01-62-C6 and on SMC2585W-G 00-02-65-01-62-C6, set the peer MAC address of
port 1 to 00-02-65-01-C5.
TIP: Plan your wireless network and draw a diagram, so that you know how an AP is connected to other peer APs or wireless bridges by WDS.
TIP: Plan your wireless network and draw a diagram, so that you know how a bridge is connected to other peer bridges by WDS. See the following figure for an example network-planning diagram.

Fig. 41. Sample wireless bridge network topology.
WARNING: Do not let your network topology consist of wireless bridges, Ethernet switches,
Ethernet links, and WDS links that form a loop. If there are any loops that exist, packets will
circle around the loops and network performance will be seriously degraded.
Fig. 42. Network topology containing a loop.
3.5.2. Security
IEEE 802.11b/g security settings include SSID broadcasts, Security mode, IEEE 802.11
Authentication algorithm, WEP keys, MAC-Address-Based Access Control.
31
3.5.2.1. Basic
Fig. 43. Basic IEEE 802.11g security settings.
For security reasons, it’s highly recommended that the security mode be set to options other
than Open System. When the security mode is set to Open System, no authentication and
data encryption will be performed. Additionally, you can disable the SSID broadcasts functionality so that a wireless client with an “ANY” SSID cannot associate with the
SMC2585W-G.
Wireless Client Isolation is a feature for the SMC2585W-G in AP mode to block wireless-to-wireless traffic between STAs so that the STAs cannot see each other. This feature
is useful for WLANs deployed in public places. This way, hackers have no chance to attack
other wireless users in a hotspot.
When the Wireless client isolation setting is set to This AP Only, wireless clients (STAs)
associated to this SMC2585W-G, which acts as an AP, cannot see each other, and wireless-to-wireless traffic between the STAs is blocked. When the setting is set to All APs in
This Subnet, traffic among wireless users of different SMC2585W-Gs in the same IP subnet
is blocked. The behaviors are illustrated in the following figures.

Fig. 45. Behavior of the “All APs on This Subnet” wireless client isolation option.
As illustrated in Fig. 44 when AP 1 and AP 2 are using the “This AP Only” option, wireless
traffic between STA 1 and STA 2 is blocked by AP 1, while wireless traffic between STA 2
and STA 3, which are associated with different APs, is still allowed. If the “All APs in This
Subnet” option is used as shown in Fig. 45, AP 1 and AP 2 communicates with each other
via an inter-AP protocol to share their STA association information to block wireless traffic
among all the STAs.
There are up to 7 security modes:
Open System. No authentication, no data encryption.
Static WEP. WEP (Wired Equivalent Privacy) keys must be manually configured.
Static TKIP (WPA-PSK). Only TKIP (Temporal Key Integrity Protocol) mechanism of
WPA (Wi-Fi Protected Access) is enabled. In this mode, you have to specify the
Pre-shared key, which will be used by the TKIP engine as a master key to generate
keys that actually encrypt outgoing packets and decrypt incoming packets.
NOTE: The number of characters of the Pre-shared key setting must be at least 8 and
can be up to 63.
IEEE 802.1x EAP without Encryption (EAP-MD5). The IEEE 802.1x functionality is
enabled and the user-name/password-based EAP-MD5 authentication is used. No data
encryption.
IEEE 802.1x EAP with Static WEP (EAP-MD5). The IEEE 802.1x functionality is enabled and the user-name/password-based EAP-MD5 authentication is used. Data encryption is achieved by static WEP.
IEEE 802.1x EAP with Dynamic WEP (EAP-TLS, EAP-TTLS, PEAP). The IEEE
802.1x functionality is enabled and dynamic WEP key distribution authentication
(EAP-TLS, EAP-TTLS, or PEAP) is used. Data encryption is achieved by dynamic
WEP.
IEEE 802.1x EAP with Dynamic TKIP (WPA). This is a full WPA mode, in which both
33
the TKIP and IEEE 802.1x dynamic key exchange mechanisms are enabled. The
SMC2585W-G is highly secured in this mode.
In the above security modes, a back-end RADIUS (Remote Authentication Dial-In User Service) server is needed if IEEE 802.1x functionality is enabled.
According to the IEEE 802.11 standard, WEP can be used for authentication and data encryption. Normally, Shared Key authentication is used if WEP data encryption is enabled. In
rare cases, Open System authentication may be used when WEP data encryption is enabled.
The Authentication algorithm setting is provided for better compatibility with wireless client
computers with various WLAN network adapters. There are three options available, including
Open System, Shared Key, and Auto.
When WEP is enabled by a security mode, the Key length can be specified to be 64 Bits or
128 Bits. The Selected key setting specifies the key to be used as a send-key for encrypting traffic from the local device side to the remote device side. All 4 WEP keys are used as
receive-keys to decrypt traffic from the remote device side to the local device side.
NOTE: Each field of a WEP key setting is a hex-decimal number from 0-9, A-F. For example, when the security mode is Static WEP and the key length is 64 Bits, you could set Key
1 to “00012E3ADF”.
3.5.2.2. MAC-Address-Based Access Control
Fig. 46. MAC-address-based access control settings.
With MAC-Address-Based Access Control, you can specify the wireless clients that are
permitted or not permitted to associate with the SMC2585W-G. When the table type is set to
inclusive, entries in the table are permitted to associate with the SMC2585W-G. When the
table type is set to exclusive, entries in the table are not permitted to associate with the
SMC2585W-G.
NOTE: MAC-address-based access control is only available when the SMC2585W-G is in
AP mode.
To deny wireless clients’ access to the wireless network:
1.
Select Enabled from the Functionality drop-down list.
2.
Set the Access control type to exclusive.
3.
Specify the MAC address of a wireless client to be denied access, and then click Add.
4.
Repeat Step 3 for each other wireless client.
34
To grant wireless clients’ access to the wireless network:
1.
Select Enabled from the Functionality drop-down list.
2.
Set the Access control type to inclusive.
3.
Specify the MAC address of a wireless client to allow access, and then click Add.
4.
Repeat Step 3 for each other wireless client.
To delete an entry in the access control table:
Click Delete next to the entry.
NOTE: The size of the access control table is 64.
Fig. 47. MAC ACL download settings.
Instead of manually entering MAC addresses to the access control table one by one, you
can prepare a text file that contains all the MAC addresses and put it on a TFTP server, and
then download the MAC ACL (Access Control List) file from the TFTP server to the
SMC2585W-G. Fig. 48 shows the contents of a sample ACL file.
Fig. 48. Sample MAC ACL file.
To download a MAC ACL file from a TFTP server:
1.
Specify the IP address of the TFTP server in the TFTP server IP address text box.
2.
Specify the name of the MAC ACL file on the TFTP server in the MAC ACL file name
text box.
3.
Click Download.

3.5.3. IEEE 802.1x/RADIUS
IEEE 802.1x Port-Based Network Access Control is a new standard for solving some security issues associated with IEEE 802.11, such as lack of user-based authentication and dynamic encryption key distribution. With IEEE 802.1x, a RADIUS (Remote Authentication
Dial-In User Service) server, and a user account database, an enterprise or ISP (Internet
Service Provider) can manage its mobile users’ access to its wireless LANs. Before granting
access to a wireless LAN supporting IEEE 802.1x, a user has to issue his or her user name
and password or digital certificate to the backend RADIUS server by EAPOL (Extensible
Authentication Protocol Over LAN). The RADIUS server can record accounting information
such as when a user logs on to the wireless LAN and logs off from the wireless LAN for
monitoring or billing purposes.
The IEEE 802.1x functionality of the access point is controlled by the security mode (see
Section 3.5.2.1). So far, the wireless access point supports two authentication mechanisms—EAP-MD5 (Message Digest version 5), EAP-TLS (Transport Layer Security). If
EAP-MD5 is used, the user has to give his or her user name and password for authentication. If EAP-TLS is used, the wireless client computer automatically gives the user’s digital
certificate that is stored in the computer hard disk or a smart card for authentication. And after a successful EAP-TLS authentication, a session key is automatically generated for wireless packets encryption between the wireless client computer and its associated wireless
access point. To sum up, EAP-MD5 supports only user authentication, while EAP-TLS supports user authentication as well as dynamic encryption key distribution.
Fig. 49. IEEE 802.1x and RADIUS.
SMC2585W-G supports IEEE 802.1x and can be configured to communicate with two RADIUS servers. When the primary RADIUS server fails to respond, SMC2585W-G will try to
communicate with the secondary RADIUS server. You can specify the length of timeout and
the number of retries before communicating with the secondary RADIUS server after failing
to communicate with the primary RADIUS server.
An IEEE 802.1x-capable wireless access point and its RADIUS server(s) share a secret key
36
so that they can authenticate each other. In addition to its IP address, a wireless access
point can identify itself by an NAS (Network Access Server) identifier. Each IEEE
802.1x-capable wireless access point must have a unique NAS identifier.
Fig. 50. IEEE 802.1x/RADIUS settings.
3.6. Configuring Advanced Settings
3.6.1. Packet Filters
The SMC2585W-G provides layer 2 (Ethernet Type Filters), layer 3 (IP Protocol Filters), and
layer 4 (TCP/UDP Port Filters) filtering capabilities. The configuration processes for the filters are similar.
Functionality: whether this filtering capability is enabled or disabled.
Policy for matched packets: how a matched packet is processed—discard or pass.
To enable a filtering rule: select the check box to the left of the rule.
3.6.1.1. Ethernet Type Filters
Fig. 51. Ethernet type filters settings.
The Ethernet type filed of the MAC (Media Access Control) header of a packet incoming
from the WLAN or Ethernet interface is inspected for filtering. In a rule, specify the
hex-decimal Ethernet type number and give the rule a name.
37
3.6.1.2. IP Protocol Filters
Fig. 52. IP protocol filters settings.
The protocol, source address, and destination address fields of a packet incoming from the
WLAN or Ethernet interface is inspected for filtering. In a rule, specify the hex-decimal protocol number, source IP address range (Source IP Address AND Source Subnet Mask), and
destination IP address range (Destination IP Address AND Destination Subnet Mask).
A source (destination) IP address range is determined by performing an AND operation on
the source (destination) IP address field and the source (destination) subnet mask field. For
example, if the source IP address field is 192.168.0.1 and the source subnet mask field is
255.255.255.0, the result source IP address range is 192.168.0.0 to 192.168.0.255.
3.6.1.3. TCP/UDP Port Filters
Fig. 53. TCP/UDP port filters settings.
The destination port field the TCP or UDP header of a packet incoming from the WLAN or
Ethernet interface is inspected for filtering. In a rule, specify the decimal Destination Port,
Protocol type (TCP/UDP), and the name of the higher-level protocol (Application Name).
38
3.6.2. Management
3.6.2.1. Basic
Fig. 54. Basic management settings.
The SMC2585W-G can be managed by Telnet. This functionality can be either enabled or
disabled.
As the SMC2585W-G allows only one administrator to log on for management, you have to
log off before another can log on. If you forget to log off or have not interacted with the Web
management interface for a period specified by the Web admin idle timeout setting (default:
5 minutes), you’ll be automatically logged off by the SMC2585W-G.
3.6.2.2. UPnP
Fig. 55. UPnP settings.
UPnP (Universal Plug and Play) enables a Windows XP user to automatically discover peripheral devices. When the UPnP functionality is enabled, you can see the SMC2585W-G in
My Network Places of Windows XP. The SMC2585W-G can be given a user-friendly name
that will be shown in My Network Places. Double-clicking the icon in My Network Places that
refers to the SMC2585W-G will launch the Web browser for you to configure the
SMC2585W-G.
NOTE: Make sure you have installed the necessary Windows UPnP components on your
Windows XP computer.
3.6.2.3. System Log
Fig. 56. System log settings.
System events can be logged to the on-board RAM of the SMC2585W-G (Local log) or sent
39
in the form of SNMP trap (Remote log by SNMP trap) or BSD Syslog (Remote log by BSD
Syslog) to a remote SNMP trap monitoring server or remote Syslog server, respectively.
See the next subsection for more information about SNMP trap settings. Set the IP address
of the Syslog server in the Syslog server IP address text box.
The system events are divided into the following categories:
„
General: system and network connectivity status changes.
„
Built-in AP: wireless client association and WEP authentication status changes.
„
MIB II traps: Cold Start, Warm Start, Link Up, Link Down and SNMP Authentication Failure.
NOTE: The SNMP Authentication Failure trap is issued when using an incorrect community
string to manage the SMC2585W-G via SNMP and the SNMP MIB II OID, snmpEnableAuthenTraps, is enabled (disabled by default).
3.6.2.4. SNMP
Fig. 57. SNMP settings.
The SNMP (Simple Network Management Protocol) functionality can be disabled, and you
can specify the name (used as a password) of the read-only and read-write community. In
addition, up to 5 SNMP trap targets can be set in the SNMP Trap Table.
To specify a trap target:
1.
Type the IP address of the target host.
2.
Type the Community for the host.
3.
Select the corresponding check box next to the IP address text box.

Fig. 58. Communication stages for a client to reach its correspondent host.
For a wireless client computer to communicate with a correspondent host on the Internet by
the host’s domain name (e.g. http://www.wi-fi.com), it first sends a DNS request to a DNS
server on the Internet. The DNS request travels first to the AP, then the AP relays this request to the default gateway of the client computer. Finally, this request is forwarded by the
gateway to the DNS server on the Internet. The DNS reply issued by the DNS server is
transmitted back to the client computer following a reverse path. When the client computer
receives the DNS reply, it knows the IP address of the correspondent host and sends further
packets to this IP address.
As illustrated in Fig. 58, the communication path could be broken at some of the stages. The
OS-provided network diagnostic tool, ping.exe, can be employed to find out TCP/IP-related
communication problems.
NOTE: If two or more NICs are installed and operating on a client computer, TCP/IP may not
work properly due to incorrect entries in the routing table. Use the OS-provided command-line network tool, route.exe, to add or delete entries from the routing table. Or, use
Windows-provided Device Manager to disable unnecessary NICs.
Solve the following problems in order:
My SMC2585W-G does not respond to ping from the client computer.
„
Are two or more NICs installed on the client computer?
‹
„
Use Windows-provided Device Manager to disable unnecessary NICs.
Is the underlying link (Ethernet or IEEE 802.11g) established?
‹
Make sure the Ethernet link is OK.
‹
Make sure the wireless settings of the wireless client computer and of the
43
SMC2585W-G match.
„
Are the IP address of the client computer and the IP address of the SMC2585W-G
in the same IP subnet?
‹
Use WinIPCfg.exe or IPConfig.exe to see the current IP address of the client
computer. Make sure the IP address of the client computer and the IP address of the SMC2585W-G are in the same IP subnet.
‹
TIP: If you forget the current IP address of the SMC2585W-G, use Wireless
Router/AP Browser to get the information (see Appendix B-3).
The default gateway of the client computer does not respond to ping from the
client computer.
„
Solve the preceding problem first.
„
Are the IP address of the SMC2585W-G and the IP address of the client computer
in the same IP subnet?
„
If you cannot find any incorrect settings of the SMC2585W-G, the default gateway
may be really down or there are other communication problems on the network
backbone.
The DNS server(s) of the client computer do not respond to ping from the client
computer.
„
Solve the preceding problems first.
„
If you cannot find any incorrect settings of the SMC2585W-G, the default gateway
of the SMC2585W-G may be really down or there are other communication problems on the network backbone.
B-3: Other Problems
My SMC2585W-G has been set to obtain an IP address automatically by DHCP.
How can I know its acquired IP address so that I can manage it using a Web
browser?
„
Use the SMC2585W-G Scan Utility (WLBrwsr.exe), which is included in the
SMC2585W-G Installation CD. This utility can discover nearby SMC2585W-Gs
and show their MAC addresses and IP addresses. In addition, it can launch the
Web browser on your computer.
NOTE: On Windows 2000/XP, SMC2585W-G Scan Utility can only be run by a user with
administrator privilege.
NOTE: SMC2585W-G Scan Utility does not scan the SMC2682W.
