I had a similar experience with my WPC54GS card. I have Win2K Pro on my
laptop, befw11s4 router/access point, static IPs, no broadcast, channel
11, wep 128 bit encryption.
It appeared as though it was getting an internet connection right at
startup, but lost it once all of the startup apps/services finished
starting. I uninstalled the drivers, removed the adapter and rebooted.
I installed the Linksys drivers and then rebooted. I shut down,
installed the adapter and booted.
I had to then edit the default profile to use my static IP and
gateway/DNS IPs as well as the WEP 128 bit encryption settings. The
Wireless Network Monitor/configuration utility provided by LinkSys is
goofy, I had to put in the IPs a few times before they actually saved.
I also changed the fragmentation and RTS thresholds to 2304 (through
device manager, advanced network adapter properties) to match the
setting on the access point. Finally seems to be working properly.
I don't know what the problem actually was, but that's what I did
before I got it all to work. I had a work-around up to now -- when the
access point was found but no internet, I went into device manager and
changed the channel to a different, random channel. Applying this
seemed to reset the adapter and allow it to connect successfully.
Hope this helps, sorry if it doesn't.
Good Luck,
Tym.
