Problems with Linksys WPC11 and Inspiron 1100

We have three Dell laptops: an Inspiron 3500 running Win98, an
Inspiron 5000 running Win2K, and a new Inspiron 1100 running WinXP
Pro. All three have a Linksys WPC11 talking to a Linksys wireless
access point, in turn connected to the Internet via DSL. I have had
great troubles getting the new Inspiron 1100 to reliably maintain an
Internet connection, while the other two PCs have worked flawlessly.
What happens is that the 1100's Internet connection seems to drop,
requiring a reset of the wireless access point.

When we originally got the Inspiron 1100, I attempted to load Win2K on
it, as I've never had a problem with this OS nor with the Linksys
wireless PC card on this OS. I could not get it to work, apparently
because this system doesn't have full Win2K support. I couldn't get
the Linksys Configuration Utility to work with the Linksys card and
driver under Win2K. Under WinXP, it was tricky to get the
configuration to work -- WinXP wanted to handle 64-bit WEP, while the
Wireless Access Point was using 128-bit.

Two questions. Has anyone succeeded in getting Win2K to work fully on
an Inspiron 1100? Has anyone solved the problem of getting WinXP on
an Inspiron 1100 to maintain its internet connection with a Linksys
wireless system?

Thanks for any suggestions.
