Trouble Shooting

Operational Problems

The Wireless adapter appears to be functioning. The Activity LED is active.
However, no network PC can be found when run in Infrastructure Wireless
Network mode

•

You have only one AP, and the PC is not placed too far from it, but the PC
still has difficulties finding the AP

1. Check that the antennas are properly connected to the

AP and the station

2. Make sure that the AP is powered on and working
3. Use

Network Watcher

to find and join with the AP

Radio signal quality indicates Yellow or Red whilst in Infrastructure mode

The connected AP is too far away

1. Use Network Watcher to find an AP with a stronger

signal

2. Move your PC closer to the connected AP

•

The adapter antenna is not connected, or its signal path is blocked by metal
casing, e.g. metal filing cabinets

1. Make sure the antenna is firmly screwed in

Arrange the antenna position to get the best radio signal
quality

Transmission or reception throughput is low during network file accessing

•

Many stations are connected to the same group and heavily utilizing the
network

1. On an Infrastructure wireless network, use

Network

Watcher

to find, and connect to, a different AP with only

a few PC connections

2. In an Ad-Hoc environment, form your own wireless

group with a different wireless domain name to start a
different channel hopping pattern

Ad-Hoc stations can't join each other

Two stations started at the same time

Reboot one station

Different Domain Name (ESSID)

Change the ESSID, using the 11Mbps Wireless LAN Utility
program, to match that of the other stations on the Ad-hoc
network

OR Go to

Control Panel/Network/11Mbps Wireless LAN PCI

Card /Properties/Advanced/ESSID

, and change it there
