Hi, Mike -
If it was an O/S or Driver update that is causing the problem I would expect
to see a flood of people with the same wireless cards having the same
problem start on the same day that the update was posted.
If the wireless was working from multiple access points and on wireless
computers at your site, and then suddenly stopped on all at once without the
SSID Broadcast being disabled or other configurations changing, then you MAY
have an interference problem.
To figure this one out you need to do some troubleshooting.
First, just try switching the access points and laptops to a different
channel. You may have to try more than one alternative channel, I have seen
things like microwave ovens and refrigerators take out 3 or 4 channels.
You can try to verify if the laptops are still working on wireless and if
the access points are still working as well. You could take one of the
laptops to a known good wireless network elsewhere and check to see if it
can see the wireless there. Possibly take one of the access points and a
laptop home or some other place and see if the laptop can see the access
point there. If they work fine somewhere else then you are probably
experiencing interference where they don't work.
Another thing you might try is to set both laptops to talk to each other
instead of to the access points and see if they can see any signal.
Hope this helps,
