5.2 Troubleshooting
A. If the utility cannot be opened or it reports that the adapter is not found, uninstall
the driver and utility and try installing again. You can also verify if the driver is installed
properly in the Device Manager.
To access the Device Manager, right-click on My Computer on your desktop, select
Properties. Go to the Device Manager tab. (For Windows 2000/XP, go to the
Hardware tab first then click on the Device Manager button).
Expand Network adapters and you should see IEEE 802.11g USB Wireless LAN. If
there is no yellow question mark or exclamation mark, the driver is installed properly.
B. If you do not see your wireless router/access point in the Available Network list,
reset your wireless router/access point and click on Refresh.
C. If WEP is ON, it means that the wireless router/access point has encryption
enabled. Be sure to set the identical encryption settings on the USB adapter’s utility
as well.
D. If the adapter has adequate signal strength and link quality, but cannot access the
Internet, verify that you are able to obtain an IP address from your wireless
router/access point.

For Windows 98SE/ME
Step 1 Go to Start, Run, type winipcfg and click OK.
Step 2 Select the adapter from the drop-down menu and click Release.
Step 3 After the IP address is released, click Renew. You should get an IP address
like 192.168.x.y (where x and y are unique numbers assigned by your wireless
router/access point). If you don’t get an IP address, reset the wireless router/access
point and then try Renew again.
For Windows 2000/XP
Step 1 Go to Start, Run, type cmd and click OK.
Step 2 At the command prompt, type ipconfig/release and press Enter.
Step 3 After the IP address is released, type ipconfig/renew and press Enter. You
should get an IP address like 192.168.x.y (where x and y are unique numbers
assigned by your wireless router/access point). If you don’t get an IP address, reset
the wireless router/access point and then try ipconfig/renew again.
E. You must have USB 2.0 compatible hardware and install the latest USB 2.0 driver
from Microsoft in order to reach the data transfer rate of 54 Mbps. If your hardware is
not USB 2.0 compatible or you don’t have the latest USB 2.0 driver installed, you will
not reach 54 Mbps.
