Wireless LAN issue

I have a customer that has a WAP54G and uses a 3com 11a/b/g Wireless PCI
Adapter - Network adapter – PCI
(3CRDAG675) to connect to it with.

Every day she shuts her computer down at the end of the day. When she
comes in the next day she turns on her computer and it will not
reassociate with the AP until the AP is powercycled. Once the Linksys
AP is powercycled her 3com Adapter immediately recognizes and associates
with it.

I was wondering if this is a known issue and if you could give me any
pointers on how I could fix it.

I have seen such, and from some playing around I came to the
conclusion that some adapters drivers
were not disconnecting from the AP during a PC shutdown, thus leaving
the device information
in the AP buffer with the AP still thinking the device was connected.
Therefore, the AP
cant have 2 of the same devices associated so a POR of the AP is
necessary. I would have her
disconnect from the AP before shutdown and see if it resolves. If so
it is probably the same problem.
If using winXp, right click the wireless icon in the tray and select
view connections then click disconnect.
Dont disable the adapter or it will have to be reenabled on power up.
