1 Introduction
1.1 Overview
Thank you for choosing this Wireless Broadband Router. This
Wireless Broadband Route is a multi-function device featuring a
wireless 54Mbps Access Point, a 4-port LAN switch and a WAN
port which extends your existing broadband Cable/ADSL
connection. It allows your Internet connection to be shared through
either the 54Mbps Access Point feature or the 10/100Base-TX
Ethernet switch, which also eliminates the purchase of additional
hub or switch. Now your wired and wireless network are integrated
to enjoy various bandwidth-consuming applications over the
Internet.
With the support of new emerged 802.11g draft standard, the
Access Point provides data transfer of up to 54 Mbps, up to 5 times
faster than 802.11b. Since 802.11g operates on the same
frequency of 2.4 GHz as 802.11b, it is backwards compatible with
existing Wi-Fi 802.11b devices. The benefit is that you can
preserve the existing 802.11b infrastructure while migrating to the
new screaming fast 802.11g.
The router can act as a DHCP server to automatically assign IP
addresses to your LAN devices. With the built-in Network Address
Translation (NAT) function, your LAN can access the Internet
through a single external IP address and at the same time is
protected against outside intruders. The router can also be
configured to filter internal access to the Internet. It is designed to
provide a reliable Internet access solution for the corporate
environment, the small office and the home user.

setting, your LAN / WLAN clients should make appropriate
changes in order to make successful connection.
3.1 Overview
To access the Wireless Broadband Router’s Web-based
Configuration Utility, at least one properly configured PC must be
connected to the device and reside on the same subnet with the
Wireless Broadband Router. The easiest way to make the
connection is attaching your host computer’s NIC directly to the
LAN port of the device, though it is also allowed to configure the
device via a wireless client.
Whatever your connection method, the computer’s Ethernet
/wireless interface must be on the same subnet with the router. As
the Wireless Broadband Router is configured with these default
values:
• IP address: 192.168.1.1
• Subnet mask: 255.255.255.0
• DHCP server: Enabled with the IP address pool from
192.168.1.100 to 192.168.1.150.
So you should set up your NIC’s or wireless adapter’s TCP/IP
settings as one of the following:
1. To use dynamic IP: Set your PC to be DHCP client to accept
the dynamic IP from the router’s DHCP server.
2. To use static IP: Set the IP address as 192.168.1.x (x is
between 2 and 254), subnet mask as 255.255.255.0 and the
gateway as 192.168.1.1 to be on the same subnet with the
router.

4.3 Configuration for NAT Routing Mode
Prior to configuring your Wireless Broadband Router, you must
decide whether to configure the device as a router or as a bridge.
This section only describes how to set up the device to act as a
router. For bridge configuration, see ”4.4 Configuration for Bridge
Mode” for instructions.
When operating as a router, the device communicates with your
ISP through the WAN port. Depending on the connection type
offered by your ISP, you may get the WAN IP address by one of
the following means:
• DHCP Client: In this connection type, your router acts as
a DHCP client and requests IP information from the DHCP
server on the ISP side. Select this option if your ISP
assigns you with a dynamic IP address each time you log
on.
• PPPoE Client: Some ISPs use a PPPoE session to make
connection with their clients. If this is the case, you should
enable this option and finish the PPPoE Client settings.
The WAN port of the device will be assigned a public IP
address from your ISP’s server.
• PPTP Client: This router supports VPN (Virtual Private
Network) pass-through for both PPTP (Point-to-Point
Tunneling Protocol) and IPSec (IP Security). VPN allows
corporations to extend their own corporate network
through private "tunnels" over the public Internet. If your
ISP, e.g., European DSL service providers, uses PPTP as
a connection method, you should use this option.
• Manual Config: If your ISP assigns you a fixed IP
address, you should select this option and manually enter
the IP information provided by your ISP.
Different configuration items will be displayed depending on your
connection type. Consult with your ISP which option applies to you
and obtain related information for correct configuration. Then
proceed to finish the following procedures.
4. Web Configuration
21
WAN Configuration for NAT Routing Mode
Click WAN in the configuration menu to enter the WAN
configuration page and carry out the procedures below.
Part 1. Configuring general settings.
1. In the WAN/LAN Relation item, select the NAT Routing
option.
This option allows the device to act as a router and use the
built-in NAT function to translate your multiple private IP
addresses to a single public IP address. However, only
outgoing requests are allowed to pass through the device
unless you specify otherwise. Outside users cannot see your
private local IP addresses. This leaves your home or business
network hidden from outside intruders.
2. In the Protocol item, select a protocol type according to the
connection type offered by your ISP.
3. If required, in the MAC Address field, enter your network
adapter’s MAC address in the format of xx:xx:xx:xx:xx:xx.
Otherwise just keep the default values.
This field allows you to clone a network adapter’s MAC
address to the WAN port of the router. Some ISPs use the
MAC address of NIC, which was connected to your
Cable/ADSL modem, for static mapping and thus give you the
same IP address each time the Cable/ADSL modem requests
for IP address for the Ethernet port. If this is the case, this
feature removes the need of asking your ISP to change the
registered MAC address and you can still use the same given
IP for the router’s WAN port.
4. In the Host Name field, you may supply a host name for this
router if this is required by your ISP. Some ISPs only respond
to a DHCP request with a valid “Host Name”. If a host name is
not necessary for your ISP, just leave it blank.

Part 2. Configuring protocol-specific settings
According to the connection type you selected above, proceed to
set up related parameters.
!
DHCP Client
If DHCP Client is your option, no other configuration is needed.
You may just click Apply to end your WAN settings. After the
connection to your ISP is established, the information provided by
your ISP will be displayed in the Status group.
Figure 4-4 WAN Configuration-DHCP Client
!
PPPoE Client
If PPPoE Client is your option, configure these fields as required by
your ISP.
PPPoE Connection Status: This item is not configurable. It
displays whether the connection is up or down.
Username/Password: Enter the username and password
provided by your ISP used to log on to Internet connection.
Connection Mode: Select your PPP connection from these
options:
Keep Alive: This feature will keep your PPPoE-enabled
Internet connection always alive. This is done by sending echo
requests periodically to ISP to prevent the connection from
being terminated by ISP.
4. Web Configuration
23
Connect on Demand: If enabled, the router will trigger a PPP
session for connection to the Internet if any client PC on your
LAN sends out a request for Internet access. However, the
router automatically disconnects the PPP session after the
WAN connection has been idle for the amount of time you
specified in the Max Idle Time box. If your Internet account is
billed based on the amount of time of your Internet connection,
you probably want to enable this option and enter an idle time
value best suitable for your network.
Manual Connect: If enabled, the system administrator can
manually connect or disconnect the PPP session by clicking
the Connect/Disconnect buttons in this page.
MTU/MRU: Allows you to adjust the Maximum
Transmission/Receive Unit in bytes for the WAN interface. The
packets larger than the specified values will be fragmented before
being transmitted.
It’s suggested not to modify the MTU/MRU settings unless
instructed by your ISP.
After you finish the WAN settings, click Apply to submit your
changes.

from which you configure the router will lose the
communication to the router. To reconnect, you will need to
renew the IP address of the PC or change to an IP address
compatible with the new LAN port IP address.
2. In DHCP Server > Service field, select whether to enable
DHPC service on the LAN and WLAN port.
The Wireless Broadband Router implements a built-in DHCP
(Dynamic Host Configuration Protocol) server on its LAN and
WLAN interface, which dynamically assigns IP addresses to
the DHCP clients on the LAN / WLAN. The DHCP server also
provides a default gateway (the router’s LAN IP address) and
DNS addresses for DHCP clients to access the Internet.
DHCP function spares you the hassle of manually assigning a
fixed IP address to each PC on the LAN / WLAN. It is probably
you already have a DHCP server on your network and you do
not enable this function. DHCP server is enabled by default.
Note: It is not allowed to have two DHCP servers running on
one LAN at the same time. If you decide to enable the DHCP
on this router, remember to disable the DHCP function of the
other device.
If you disable DHCP server, just click Apply to submit your
changes. Otherwise proceed to next step.
3. If DHCP server is enabled, enter the fields below:
DHCP Lease Time: Specify the time that a network device
can lease a private IP address before the DHCP server
reassigning the IP address.
IP Pool Range: Specify the starting and ending IP address of
the IP address pool. Whenever a network device requests an

Internet session, the router will allocate an unused IP address
from this pool and lease them to the device for a specified
amount of time.

4.5 Wireless LAN (2.4G) Configuration
The Wireless Broadband Router implements Access Point
capability which connects wireless clients to a wired LAN. It allows
wireless nodes to access network resources and share the
broadband Internet connection. With the default values, the router
(Access Point) can be easily associated by a wireless client. We
suggest that you customize the wireless settings to prevent
unauthorized association.
!
Basic Configuration
Access Point Name: The name used for identifying the Access
Point. The default value is 11g AP.
SSID: Service Set ID. It uniquely identifies a logical network
domain name of your WLAN. The default value is 11g AP.
Network Type: An “Open” AP will periodically broadcast its SSID
to allow the wireless clients to recognize their presence. However,
this creates a security hole since any wireless station with SSID set
to “any” or got the broadcast may associate to your AP. It is
recommended to set this option to Closed to have your AP only
accept stations whose SSIDs are the same as this AP.
Country: Select the country where you use this AP. When the
country setting is changed, the AP scans only the legal frequency
channels allowed in that regulatory domain.
Channel ID: The radio frequency used for communication.
Available channels vary according to the regulations in the country
you specified in the Country drop-down list. Select a channel out
of the available cannels or use the default channel.
!
Security
Data Encryption (WEP Mode): Select whether to use WEP (Wired
Equivalent Privacy), an authentication algorithm which encrypts
your data and protects your wireless network against
eavesdropping.
Wireless Broadband Router User Manual
32
• Off: The data is not encrypted when it is transferred from
one station to another. This is the default. For security
concern, we strongly suggest you enable WEP function.
• On: The data is encrypted by the default key (with its
radio button selected) before being transmitted. If WEP is
set to On, you should proceed to enter WEP keys.
Authentication Mode: Select Open System or Shared Key or
Shared Key only.
Authentication is a process in which the AP validates if wireless
clients are qualified to access the AP’s service. This happens prior
to any wireless client can associate to an AP. The IEEE 802.11
defines two types of algorithms in authentication: the “Open
System” and “Shared Key”.
• Open System: The authentication is done through a
pseudo process, accepting all kinds of requests, mainly
used in cases where connectivity is more important than
security.
• Shared Key : Utilizes WEP capability to further verify if a
wireless client is authorized to share this AP’s resource. If
the client has the wrong key or no key, it will fail
authentication and will not be allowed to associate with
the AP.
If you select Open System or Shared Key, wireless stations with or
without correct WEP keys can be authenticated by the AP.
Yet if Shared Key only is selected, you must enable WEP function
and define your WEP keys. The keys are used both to authenticate
wireless clients and encrypt outgoing data.
WEP Keys: Enter one to four WEP keys in either ASCII or
Hexadecimal format. You can use 64 bits or 128 bits as the
encryption algorithm. The higher the bit number, the greater the
complexity and the security of the encryption.
Note that when using Hexadecimal format, only digits 0-9 and
letters A-F, a-f are allowed. Valid key length for each encryption
type is as below:
4. Web Configuration
33
HEX Format ASCII Format
64 Bit 10 hexadecimal digits 5 ASCII characters
128 Bit 26 hexadecimal digits 13 ASCII characters
Specifing a default key to encrypt outging data
Aside from entering your WEP keys, you should select one of the
entered keys to encrypt the data before being transmitted. The AP
always transmits data encrypted using this WEP Key. The key
number (1,2,3,4) is also transmitted. The receiving station will use
the key number to determine which key to use for decryption. If the
key value does not match with the transmitting station, the
decryption will fail. To ensure successful decryption, have your
wireless stations set identical key tables.
Note: All Wireless Stations must use identical encryption algorithm
level and Key values (same key position in its key table) to ensure
successful data transmission.
!
Access Control
MAC Address Access Control: This AP has the capability to
control the wireless client access based on the MAC address of a
wireless client. We offer you the flexibility to customize your own
control policy based on these options:
• Allow: If selected, only the wireless client whose MAC
address is in the Allow List is allowed to access this AP.
• Deny: If selected, only the wireless client whose MAC
address is in the list cannot access this AP. Others clients
are granted access.
• Disable: No access control. All the clients are allowed to
access this AP.
When entering MAC address in the list, up to 16 MAC entries are
allowed.

!
Advanced Configuration
We suggest you not to modify the Advanced parameters unless
specific requirement is required. The parameters are described as
below:
Beacon Interval: Defines the periodic interval at which the Access
Point sends out a beacon.
RTS Threshold: Request to send threshold. It specifies the packet
size beyond which the AP invokes its RTS/CTS mechanism.
Packets that exceed the specified RTS threshold trigger the
RTS/CTS mechanism.
Fragment Threshold: It determines whether packets will be
fragmented and at what size. On an 802.11 wireless LAN, packets
exceed the fragmentation threshold are fragmented, i.e., split into,
smaller units suitable for the circuit size. On the other hand,
packets smaller than the specified fragmentation threshold value
are not fragmented.
DTIM: Specifies the Deferred Traffic Indicator Map (DTIM) period.
This value determines at which interval the AP will send its
broadcast traffic. The default value is 3.
Rate: The default setting, Auto, allows the AP to automatically use
the fastest possible data rate. Selecting a specific rate forces the
AP to transmit at a particular speed.
Basic Rate Set: The Default option uses 1 or 2 Mbps for 802.11b
and 6, 12 or 24Mbps for 802.11g as the basic rate of your wireless
network. The All option uses 1, 2, 5.5, 6, 9,11, 12, 18, 24, 36, 48,
or 54Mbps. The wireless clients must support the basic rate to
successfully associate with the AP.
54g
Mode: 54g is Broadcom’s latest wireless technology which
offers the fastest possible data rate of 54Mbps under 802.11g draft
specification. This item allows you to choose from these
communication options:
• 54g Auto: Both 802.11g and 802.11b clietns can
communicate with this AP. The data rate will be
automatically adjusted.
4. Web Configuration
35
• 54g Performance: Only 802.11g wirless clients can
communicate with the AP.
• 802.11b Only: Only 802.11b clients can communicate with
the AP.

4.6 Filters
When your Wireless Broadband Router operates as a router, the
built-in NAT function provides your LAN with the Internet access
via the single public IP of the WAN port. That means all network
devices are allowed to access various Internet service. Under this
circumstance, network security becomes an important issue and
system administrators may need to build access control to protect
the network.
The filter feature serves as a basic firewall security measure for
your network. When filter function is enabled, the Wireless
Broadband Router inspects all data packets arrive from LAN side
and determines if packets are allowed to pass through the WAN
port depending on whether packets match your filter rules and
whether your filter type is Listed Pass or Listed Block.
In addition to filter settings, the Filters page also allows to configure
other firewall settings, including WAN Management, WAN Port
Ping Reply and Report Log to TFTP Server.
Specifing Your IP Filter Rules
If you are going to specify your filter rules, follow the procedures
below:
1. In the Firewall item, select the Enable option.
2. In the Filter Type item, select the action (Listed Pass or
Listed Block) to be performed on the IP packets matching
your filter rules.
3. In the four filter types, select whether to enable or disable each
filter.
4. If a filter is enabled, enter the criteria in provided fields. Click
More to add more criteria if required. See next section for
more information.
5. Click Apply to commit your changes.
4. Web Configuration
37
Filter Types
When setting up filter rules, you can define the Filter rules based
on the LAN machine’s MAC address, IP address or the protocol
type of the data packet. Each filter type is described as below.
Note: Based on OSI reference model, MAC Filters demand higher
priority than IP Filters while IP Filters higher than Port Filters.
MAC Filters: The MAC address of the LAN machine from which
packets are allowed (or prohibited) to pass through the WAN port.
Up to 12 entries are allowed.
IP Filters: The range of IP addresses of the LAN machines from
which packets are allowed (or prohibited) to pass through the WAN
port. You may enter the same address in both (Start and End)
fields to define a single IP address. Up to 5 entries are allowed.
TCP Port Filters: Allows (or prohibits) certain LAN machine to use
TCP based service in the specified port range through the WAN
port. Up to 12 entries are allowed.
For example, to allow (or prohibit) local PC 192.168.1.210 to use
FTP service (using TCP port 21):
IP Address Start End
192.168.1.210 20 21
UDP Port Filters: This field allows you to allow (or prohibit) certain
LAN machine to use UDP based service in the specified port range
through the WAN port. Up to 12 entries are allowed.
For example, to allow (or prohibit) local PC 192.168.1.210 to use
ping service (using UDP port 53):
IP Address Start End
192.168.1.210 53 53
Wireless Broadband Router User Manual
38
Filter Scenario of the Wireles Broadband Router
When setting up your firewall policy, note the filter scenario used
by the router:
When Filter Type is Listed Block:
If all the filters are disabled: No filter rule is specified to
block any packet. All packets can pass through the WAN
port. (Defaults)
If any filter is enabled: only the packets matching the
specified rule are blocked; other packets can pass through
the WAN port.
When Filter Type is Listed Pass:
If all the filters are disabled: No filter rule is specified to
allow any packet to pass. All packets are blocked.
If any filter is enabled: Only the packets matching the
specified rule can pass; other packets are blocked.
Figure 4-14 Filters
4. Web Configuration
39
Viewing Filter Log
When filter feature is enabled, the router will keep a record of the
packets discarded. To view the firewall activity log, go to System
Overview > Firewall > Activity Log and click the Show Log
button. Filter activity log is displayed in a separate window with a
maximum of 32 entries. Clicking the Update button allows to
refresh the log with newly reported data. The log types are defined
as below:
Type Description
1 Blocked packets, from WAN side, by DoS (Deny of Service)
protection mechanism.
2 Blocked packets, from LAN side, by MAC/IP/TCP/UDP filter.
Other Firewall Settings
WAN Management: Available only when Firewall is enabled. If
available, this item is disabled by default that rejects any external
access from the WAN port. If this option is enabled, a WAN Port
filed is displayed with the default value 80. If required, you may
enter another port number used by the external WAN access.
If WAN Management is enabled using a non-80 port, the router’s
HTTP service (Web Configuration Utility) will be accessible via the
router’s WAN port IP address following by a colon and the non-80
port:
http://<WAN IP address>:<non-80 port>
For example, if 1234 is entered, a remote user can access and
configure the router at http://203.1.2.3:1234 where 203.1.2.3
indicates the WAN port’s IP address.
If WAN Management is enabled using standard port 80, no suffix is
required.
If WAN Management is enabled using port 80, your publicly
accessible Web server (if any) on LAN side should use a non-80
Wireless Broadband Router User Manual
40
HTTP port. And you need to use the Forwarding feature to shift
external HTTP requests to the non-80 port number used by the
Web server on LAN side.
WAN Port Ping Reply: Available only when Firewall is enabled. If
available, this setting determines if an external host will get reply
when trying to ping the IP address of your WAN port. It’s disabled
by default.
Report Log to TFTP Server: Available only when Firewall is
enabled. If available, it specifies whether to report firewall event log
to your TFTP server. If enabled, a LAN TFTP Server field is
present for you to specify the IP address of the TFTP server. All
the filter logs are sent to TFTP server although only 32 entries are
displayed in Show Log window (see System Overview page).

41
4.7 Forwarding
This page allows you to configure the Forwarding and DMZ
(De-Militarized Zone) features. Unlike Filter which governs
outgoing traffic, Forwarding is used to provide external access to
your local machines. This is commonly used when you have
publicly accessible virtual servers on your local network.
By default, forwarding entry is empty and any external access to
your LAN is blocked. Once you define a forwarding entry, incoming
packets (identified by its port number) that match your Forwarding
criteria will be forwarded to the port range of the specified local
machine. Otherwise packets are blocked. Forwarding serves as a
measure of security that protects your network from hazardous
packets.
However, if you designate a DMZ sever, incoming packets that do
not match the forwarding criteria will be redirected to the DMZ IP
address. That is, forwarding demands a higher priority than DMZ.
Setting Up Forwarding Entries
To set up your forwarding entries, enter these fields:
DMZ IP Address: DMZ setting allows a local machine to be
exposed to the Internet. If you specify a DMZ host here, the
incoming packets containing no port information specified in the
Forwarding table are forwarded to the DMZ host.
TCP Port Forwards: In the first Start and End fields, define the
port range for the incoming TCP service you want to forward. In the
IP Address filed, enter the IP address of the virtual server to which
packets are forwarded. The Start/End fields on right side define
the port range for the TCP service on the virtual server.
For example, you have a virtual server 192.168.1.210 running FTP
service and you allow external access by the setting below:
Start End IP Address Start End
20 21 192.168.1.210 20 21
Wireless Broadband Router User Manual
42
UDP Port Forwards: The configuration is the same as setting TCP
Port Forwards, only that the entry applies to UDP service.
When the router gets outside TCP/UDP requests destined for the
WAN port, it determines whether the services are allowed
according to your forwarding settings. For example, if you do not
specify FTP virtual service in Forwarding table, incoming FTP
requests (identified by port number in packets) are blocked or
otherwise sent to DMZ host (if specified). On the other hand, if an
FTP forwarding entry has been set up, the FTP requests will be
able to be forwarded to the specified machine.
If you have a Web server on your network…
If you enable WAN Management (i.e., allow external access from
the WAN port, see “4.6 Filters”) and want to designate another
Web server on your local network, take either of the procedures
below to avoid port confliction:
Option 1: In Filters page, with WAN Management enabled, enter
a port number other than 80 (for example, 1234) and reserve the
number 80 for your Web server.
If any external host wants to access your Web management server
through the WAN port, it should use the address below:
http://204.71.200.143 (i.e., the WAN IP address):1234
Option 2: Have WAN Management to use the standard port
number 80 and your Web server (e.g., 192.168.1.4) to use another
port number (e.g., 8080). In this case, you need to shift the
incoming HTTP request (destined for local Web server) to port
8080 of your Web server, the forwarding entry may look like this:
Start End IP Address Start End
8080 8080 192.168.1.4 8080 8080
With the settings above, an external host trying to access your
local Web server should use the address like this:
http://204.71.200.143 (i.e., the WAN IP address):8080
4. Web Configuration
43
If you do not enter the suffix “:8080”, the external host’s packets
will contain the standard port number 80 and the router will not
forward the packets since no forwarding entry matches. As a result,
if a WAN computer tries to access the LAN’s Web server, it will turn
to access the Web service on the WAN port, i.e., the Web
Configuration Utility of the router instead.

5 Troubleshooting
I cannot access the Web-based configuration utility from the
Ethernet computer used to configure the router.
• Check that the LAN LED is on. If the LED is not on, check
that the cable for the LAN connection is securely
connected.
• Check the your computer resides on the same subnet with
the router’s LAN IP address.
• If your computer act as a DHCP client, check the your
computer has been assigned an iP address from the
DHCP server. If not, you will need to renew the IP address.
See the check/renew IP address section under ‘3.2
Setting up TCP/IP’ for instructions.
• Use the ping command to pint the router’s LAN IP address
to veify the connection.
• Make sure your browser is not configured to use a proxy
server.
• Check that the IP address you entered is correct. If the
router’s LAN IP address has been changed, you should
enter the reassigned IP address instead.
I can browse the router’s Web-based configuration but cannot
access the Internet.
• Check the WAN LED is illuminated. If not, check the
physical connection between the router and the
DSL/Cable modem is OK.
• If WAN LED is illuminated, open the WAN page of the
Web configuration utility and check the status group to
see if the router’s WAN port has successfully obtained an
IP address.
• Make sure you are use the correction method (DHCP
client, PPPoE client, PPTP client or Manual) as required
by your ISP. Also ensure you have entered correct
Wireless Broadband Router User Manual
48
settings provided by your ISP.
• For cable users, if you ISP required a fixed Ethernet card
MAC address, make sure you have cloned the network
adapter’s MAC address to the WAN port of the router.
(See the MAC Address field in WAN page.)
My wireless client cannot communicate with another Ethernet
computer.
• Ensure your wireless adapter functions properly. You may
open the Device Manager in Windows to see if the
adapter is proper installed.
• Make sure your wireless client is configured to use
Infrastructure mode. Also make sure the client uses the
same SSID and security settings (if enabled) with the AP.
• Ensure that the wireless adapter’s TCP/IP settings are
correct as required by your network administrator.
• Check that the wireless adapter’s MAC address is not in
the MAC address list if Access Control is enabled to use a
deny list. (See Wireless LAN page in Web configuration
utility.)
• If you are using a 802.11b wireless adapter, check that the
54g Mode item (in Wireless LAN page) is not configured
to use 54g Performace. On the other hand, if you are
using 802.11g adapter, check the 54g Mode item is not
configured to use 802.11b Only.
• Use the ping command to verify the wireless client’s
communication.with the router’s LAN port and with the
opposite computer. If the wireless client can successfully
ping the router’s LAN port but fails to ping the opposite
computer, then verify the TCP/IP settings of the opposite
computer.
After I retrieved my saved configuration file, the retrieved
settings do not take effect.
• After you retrieved the desired file, you must reboot the
router to have retrieved settings take effect.
