APPENDIX A: TROUBLESHOOTING
The USB icon does not appear in our icon tray.
• Make sure that you have installed the Utility from the attached CD .
The Utility is installed and appears in the icon tray, but no networks are found.
• If no networks are listed, you may not be within range of any network – higher gain
antennas maybe necessary.
• If you have a portable computer, move it within close range to an access point or
router and see if the network can be seen. If so, the adapter is functioning and your
first attempt may have been out of range.
Why won’t the Utility Tool funtion properly in Windows XP?
• If you are using Windows XP as your operating sytem, the “Zero Configuration”
feature/tool of Windows XP must be disabled first, then the AIR802 Wireless Utility
can be used. To disable:
Click Start >> Control Panel >> Administrative Tools >> Services. Select Disabled in the
Startup Type field of Wireless Zero Configuration Service to enable the Wireless Zero
Configuration Service. The default value of Wireless Zero Configuration Service is
Automatic.
How can I improve the signal levels even further?
• If your USB adapter is plugged directly into a computer low to the floor, you may
benefit by adding an USB Extension cable and then placing the USB adapter on the top
of a desk or table, at a higher level more in line with the wireless router or access
point.
• Wireless communications is a 2 ‐ way communications link. Often, the weak link is the
PC itself, but if after installing the USBadapter you still have weak communications it
maybe due to interference from other devices in the 2.4 GHz
band and/or your wireless router or access point may offer low RF output power and
receiver sensitivity. If this is case you may attempt to upgrade the antenna on the
router and the USB adapter or purchase a high quality router.
• You can consider alternative antennas for the USB adapter with higher gain
omnidirectional “rubber duck” options, or directional gain atennas where the RF
energy is focused towards a specific direction.
