SSID & Channel
Here is where you may modify the SSID and
Channel of your Wireless-G Broadband Router.
• SSID (Service Set ID, or Network Name):
Enter the name you wish to give your Wireless-G
Broadband Router (ex. “JOHN” or “IOGEAR”).
Every Wireless Clients (PC card, USB and PCI
adaptors) in your network must be configured to
accept with the same SSID.
• Channel
It can be left as Default, unless you plan on using
multiple access points. When multiple Wireless
Networks presenting, please ensure they are not
using the same channel, preferably at least 5
channels apart to each other.
• Accept Broadcast SSID
By broadcasting SSID, all wireless devices at
surrounding area can see your wireless router and
easy to associate with it. However, it is a good
security practice not to broadcast SSID, just
configure SSID info to those client devices you want
them to access you network.
Configuration Utility
It allows you to configure the setting of network
authentication and data encryption.
• Network Authentication:
You can specify the authentication type.
- “Both” allows wireless client devices access
your router no matter with shared key or not.
- “Share Key” only allows devices with same
WEP (Wired Equivalent Privacy) key to
access your wireless router.
- “802.1X” and “WPA” require you to type in
Radius server IP and server key. Please
check with your Network Administrator for
related information.
- “WPA-PSK” needs a pre-shared key to be set
on your wireless router and all wireless client
devices.
35
Authentication & Encryption
Configuration Utility
• Encryption:
- WEP Configuration
36
Configuration Utility
Click the drop-down menu to select WEP to enable
the WEP function and select 64 bits or 128 bits. The
128 bits gives a higher level of security. The
selection must be the same between all connected
network devices. For 64-bit WEP key, it should be
five ASCII characters (a-z and 0-9, for example:
gear56) or ten hexadecimal digits in length (a
through f, and 0 through 9, for example:
2af30bc9d5); for 128 bit WEP key, the length will be
13 characters for ASCII or 26 digits for Hexadecimal.
WEP keys 1-4 enable you to create an encryption
scheme for wireless LAN transmissions.
37
Configuration Utility
WPA and WPA-PSK configuration
Wi-Fi Protected Access (WPA) is a sub-set of the
forthcoming IEEE 802.11i security standard. WPA
addresses those known weakness of WEP and
provides stronger security to wireless network.
IOGEAR Wireless-G Broadband Router supports
three authentication modes:
• 802.11x (need RADIUS server to authenticate
the clients, using WEP keying)
• WPA (same 802.1x, but with TKIP keying
support); WPA-PSK (Pre-Shared Key, no
RADIUS server needed)
- WPA-PSK
38
- WPA
Configuration Utility
There are two ways to configure WPA Pre-Shared Key:
1. PassPhrase Mode: Input a phrase into the field.
The Wireless-G Broadband Router will automati-
cally generate a Pre-Shared Key based on the
phrase you enter. The phrase can be within 8 to 63
characters (we recommend at least 12 characters
to achieve a sufficient level of security).
2. Hex mode: Input 64 hexadecimal digits. Please
write down the key you enter. You will need to enter
same key to your wireless client side.
WPA Group Rekey Interval
This router could change the group key periodically.
Enter the period you want into the WPA Group Rekey
Interval field.
Encryption Type
The current version only supports TKIP encryption.
AES encryption will be available soon.
39
Configuration Utility
RADIUS Server IP
Please enter the IP address of RADIUS server
RADIUS Server Port
This field specifies the port on which RADIUS server
is listening.
RADIUS Server Key
This field carries the shared secret for RADIUS
authentication. Some information need to be
encrypted in a RADIUS packet, this key is used to
encrypt and decrypt this information (such as
password).
Reconfirm RADIUS Server Key
Make sure RADIUS Server Key is correct.
WPA Group Rekey Interval
It is the same as WPA-PSK configuration
Encryption Type
It is the same WPA-PSK configuration
Note:
To complete the WPA operation, you also need to enable the
WPA client at the wireless client site (the computer running
wireless client’s devices, such as the GWP511 Cardbus card
GWP512 Cardbus Card or GWU513 USB adaptor).
Microsoft provides a free WPA upgrade for Windows XP
Service Pack 1 (SP1) and later or Windows Server 2003. For
any OS other than Win XP, there is client software available
from third-party suppliers such as Funk Software’s Odyssey
(www.funk.com). IOGEAR’s GWP512 Wireless-G Network PC
Card has it built-in.
The WPA client for Windows XP can be found in the Microsoft
Knowledge Base Article 815485 (http://support.microsoft.com/
default.aspx?scid=kb;en-us;815485) or downloaded directly
from Microsoft http://www.microsoft.com/downloads/
details.aspx?FamilyID=009d8425-ce2b-47a4-abec-
274845dc9e91&displaylang=en
40
Configuration Utility
After installed, the Windows WPA Client will update the
wireless network configuration dialog boxes to support new
WPA options.
1. Click Connect To>Wireless Network Connection
to bring up the dialogue window of Wireless
Network Connection Status. Click the
Properties box to bring up next dialogue window.
2. In the Wireless Network Connection Properties
window, under Wireless Networks tab, please
check the box of “Use Windows to configure my
wireless network settings” to turn on the
Wireless Zero Configuration service. Select the
wireless access point you want to associate to,
then click Configure box at the right side to bring
up next dialogue window.
3. Set up your WPA configuration by selecting the
Network Authentication mode and Data
encryption, and input same Network key as you
input at the Wireless-G Broadband Gateway.
Then, you are served by a more secured wireless
network
41
Configuration Utility
Here you can configure Wireless radio settings.
Please note that these settings are for advanced users
or network administrators. If you are unfamiliar with
how to configure these parameters, we recommend
that you keep them at their default value.
• Mode: The Wireless-G Broadband Router can be set
at three wireless modes: Auto, 802.11g only and
802.11b only. If both 802.11g and 802.11b clients
presenting at your network, please select “Auto”
mode (This is default mode). “802.11g only” mode
only supports 802.11g clients, and gives better
performance to whole network. However, all 802.11b
clients will not be able to use your network at this
mode setting. In some situation, 802.11b clients with
old drivers cannot work with Auto mode; “802.11b
only” mode can accommodate this problem, but
decrease the performance of 802.11g devices.
42
Configuration Utility
Radio Setting
• Beacon Period: Beacons are packets sent by the
router to synchronize a wireless network. The value
of beacon interval is depending on the environment
where the router is operating. Specify a Beacon
interval value between 1 and 1000(units: ms). The
default value is set to 100 milliseconds, i.e., ten
beacons per second.
• RTS Threshold: The RTS threshold is the packet size
at which packet transmission is governed by the
RTS/CTS transaction. Each station can have a
different RTS threshold. If you encounter inconsistent
data flow, only minor modifications are recom-
mended. The default value for RTS Threshold is set
to 2347.
• Fragment Threshold: This value should remain at its
default setting of 2346. If you experience a high
packet error rate, you may modify slightly your
“Fragmentation” value within the value range of 800
to 2346. Setting the Fragmentation value too low may
result in poor performance.
• DTIM Period: Enter a value between 1 and 255 for
the Delivery Traffic Indication Message (DTIM). A
DTIM is a countdown informing clients of the next
window for listening to broadcast and multicast
messages. When the router has buffered broadcast
or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its
clients hear the beacons and awaken to receive
the broadcast and multicast messages. The default
value for DTIM interval is set to 1.
