No Internet or File Sharing With Dell 1150 Wireless

Archived from groups: alt.internet.wireless,alt.sys.pc-clone.dell (More info?)

I used to be able to get to the 'net but I took some bad advice in trying
to get file and printer sharing to work and now I'm dead in the water.
Actually, I can no longer even get dialup to work.

I have a Dell Inspiron 4000 running Win 98 SE (not what came with it) and
have a Dell 1150 wireless card. My "home base" is a Compaq Presario also
running Win 98 SE. The wireless router is a Dell 1184 and I have a no-
name cable modem courtesy of RoadRunner. I have 'net access through the
router and cable modem working just fine on the desktop unit and the 'Net
USED to get through to the laptop as well. I have never had file sharing
work at all in spite of checking and rechecking EVERYTHING a zillion
times (this ordeal started Christmas Day, in fact). I'm about to try to
sell the 1184 and 1150 on eBay and start over with someone else's gear.

The bad advice (from the Knowledge Base) was to reinstall Win 98 with the
1150 in place and the router active, etc, on the theory that Win would
detect everything and install all of the right stuff. WRONG. I have since
uninstalled and reinstalled the 1150 drivers, removed and replaced the
card in the Device Driver and Network setups, etc etc ad nauseum, no
dice. I have a perfect signal to the 1150 showing in the Client Manager
on the laptop but have a warning, "Modem status cannot be displayed". In
Network Neighborhood the desktop computer shows, but Explorer gives me a
"not accessible" message when I double click on it. It crashes if I try
to right click. I've tried Dell's driver updates (downloaded here, saved
to CD and moved over).

With the dialup I can get a modem connection, but it shows "Talking to
the server..." without ever getting through. Connecting the cable modem
direct to the laptop, no dice.

Anyone have any idea what the heck is going on here?
