U.S.Robotics Wireless MAXg USB Adapter Guide D'installation page 13

If you do not have a connection to your Wireless MAXg Router, you can try the following solu-
tions:
1 Ensure that your computer is close enough to your router to receive a signal and that there
is nothing interfering with the signal, such as a microwave oven or a concrete wall. If your
router broadcasts its network name, you can use your computer's wireless utility to scan for
it. (This is typically called a "site survey.") If your utility can't detect your router, it may be a
signal problem.
2. Ensure that the wireless utility is using the correct network name and security settings for
your router. Settings such as network name, security method (WPA, WEP, etc.), and security
keys must all match. If your router is using WPA encryption, each wireless card or adapter
must support WPA encryption. If you are using a Wireless PC Card, PCI adapter, or USB
adapter that does not support WPA encryption, you will not be able to connect to the Wire-
less MAXg Router and will need to use WEP encryption. Please refer to the Configuration
section of this User Guide for information on changing the security settings.
3. If you have enabled MAC filtering, is this computer permitted to connect to your router?
Please note that MAC filtering refers to specific wireless adapters. If you use MAC filtering
and you've changed wireless adapters, you will have to add the MAC address of the new
wireless adapter to the router.
You've probably noticed that you need to access your Wireless MAXg Router in order to check
some of these things. We'll do that in the next step.
If none of these work, you can try a wired connection between your computer and your router by
connecting an Ethernet cable between your computer's LAN port and a LAN port on the router.
(Ensure that the corresponding LAN port LEDs are lighted.) If a wired connection works, the prob-
lem is almost certainly with your computer's wireless connection to the router. You should then
try the previous steps again.
Step 2: Is your Wireless MAXg Router responding?
If you have a wireless or wired connection to your Wireless MAXg Router, open your Web browser
to the router's address: 192.168.2.1 (Please note that if you've modified the router's LAN IP
address, you should use the new one.)
If the Wireless MAXg Router's Web interface doesn't appear, your computer may need to re-
establish a connection to your router:
Release and renew your computer's network connection.
Windows XP, 2000, and NT users:
Press Start and select Run.
Type cmd and press ENTER.
Type ipconfig /release and press ENTER.
Type ipconfig /renew and press ENTER.
Type exit and press ENTER.
Windows Me, 98, and 95 users:
Press Start and select Run.
Enter winipcfg and press ENTER.
Click Release.
Click Renew.
Close the application.
Your computer should acquire an IP address (such as 192.168.2.5) from the router.
Try to access the router's Web address at http://192.168.2.1
If the Wireless MAXg Router's Web interface doesn't appear, the router may need to be restarted:
