wireless trouble

Archived from groups: microsoft.public.windows.networking.wireless (More info?)

I have the following problem with my wireless network.

I have a Linksys BEFW11S4 AP/router connected to a Linksys cable
modem. I can not always connect with my Gateway M275 laptop with
Intel 2200BG wireless adaptor, but have no problem with my Gateway
450X (not sure what that uses for adaptor hardware.) The M275 has
SP2, the 450X has XP SP1

About 25% of the time, I turn my laptop on, it connects and works
fine. 75% of the time it gets hung up acquiring a new IP address.
(IP address at this point is 0.0.0.0) After trying for a while, I get
an error message saying I have limited or no connectivity. Sometimes
I can select "repair" and it will connect. Usually I get the same
"limited or no connectivinty" message. If I press repair enough times
(3-4) it will usually connect.

Once it is connected, it will normally work for as long as I care to
use it, but one time in 10 my connection will drop out after a half
hour or so.

Signal strength is excellent, router has been flashed to latest
firmware, latest Intel driver has been installed (Gateway doesn't
offer any driver updates for this hardware) WPA-PSK security enabled.

I have not had an opportunity to use this laptop with other wireless
networks yet, so I don't know if the problem is with my AP or my
laptop, but suspect it is with the laptop since the other laptop works
fine.

Any suggestions? Thanks in advance.
