I have a new Gateway CX200x with an Intel Pro/Wireless 2200BG built-in
adapter. I can connect to any three of the wireless routers I have at
work here. The problem that exists is I cannot obtain an IP, nor if I
assign one manually can I connect to anything, pinging will time out.
Two of the routers are setup with encryption, one is not. If I take
the notebook home and connect to my wireless router at home, it
connects and obtains an IP address immediately. I've deleted entries
in both the DNS and DHCP servers at work in relation to this notebook,
it didn't help at all. Other unusual circumstances... if I connect the
notebook in the office wirelessly, but it doesn't obtain an IP, and
then connect a Cat-5 cable to the 10/100 port, which does obtain an IP,
then the wireless adapter will also obtain an IP address shortly
thereafter, and a different IP from the Cat-5 connection. I have to
assume that one or more files are corrupted that the wireless is using.
Or maybe somehow a file is looking for my wireless router at home?
I've unistalled and re-installed the adapter since, but nothing has
changed. I even un-installed Norton Security that came with the
notebook thinking that was the problem. I ran the WinSock Fix located
at, http://www.spychecker.com/program/winsockxpfix.html that I had read
about it in this forum... that did nothing. I made sure that Windows
Firewall was turned off, and that I had no other software firewalls
that may have been installed. If the wireless adapter didn't work at
home, I'd assume it was a hardware issue... but it works fine there...
and within the last week it worked fine in the office... now it
connects... and fails to obtain an IP. Any help would be greatly
appreciated. Thank you.

P.S. I must say that all notebooks in the office here have no trouble
connecting wirelessly. I'm also running XP PRO SP2 Tablet PC.
