No operation.

Verify the access point configuration.
Review access point firmware revisions and update firmware 
if necessary.
Make sure that there are no duplicate IP addresses on the 
network. Unplug the access point and ping the assigned 
address to make sure that no other device responds to that 
address.

Access point powers up, but 
does not associate with wireless 
clients.

Confirm that the service area on the access point matches that 
on the clients.
Verify that the clients are operating correctly.
Make sure that security settings on the access point match 
those on the clients.
Make sure that the access point antennas are positioned 
properly.
Check the range and move clients closer if necessary.

Mobile users do not have 
roaming access to the access 
point.

Make sure that all access points and wireless devices in the 
ESS in which mobile users can roam are configured to the 
same WEP setting, SSID, and authentication settings.

Slow or erratic performance.

Try changing the wireless channel on the access point.
Check the access point antennas, connectors, and cabling for 
loose connections.
Check the wired network topology and configuration 
for malfunctions.

Running on a computer 
connected to the wired LAN, 
the 3Com Device Manager 
cannot find an access point.

The 3Com Device Manager cannot discover devices across 
routers. Make sure that the computer is connected on the same 
segment as the access point.

After you specify an IP address 
for an access point, the 3Com 
Device Manager continues to 
point to the old IP address 
when you select the access 
point in the Wireless Network 
Tree.

In the 3Com Device Manager window click the Refresh 
button to refresh the Wireless Network Tree. Then click the 
access point in the Wireless Network Tree and click 
Properties. The IP address you specified is now listed. If you 
want to continue configuring the access point, 
click Configure.
