You might ask your IT group if the modifications they rolled down the
network to your computer actually disabled access to all wireless
networks except those which match their own parameters. This might be
one of their ways of keeping tighter control on (a) what the machine
is used for and (b) what is allowed to intentionally or
unintentionally find its way onto the machine.

Sounds like a good lead. Perhaps it's some restriction your IT setup
(via update) in the Group Policy ? One can appreciate that there
would be reasons for restrictions.

Doesn't sound like a typical driver/hardware problem. Not across two
different wireless adapters. Have you tried installing another (not
the netgear) adapter - a USB one, say?

--------------------------------------------------

Jeff L, on another current thread, mentions approaching problems by
asking the question in reverse, so the question here might be:

How do you set up an xp machine so that it could only connect to one
wireless network and that additional wireless network adapters could
not be installed ? And prevent the user from changing that setting?


Very clear, well informed problem description by the way.
