Constant hanging was cured, as suggested here, by
going to WPA encryption from WEP.
However now the things sometimes disconnect from
the wireless network and don't try to reconnect,
which has to be a software error.
You have to disable and then enable the wireless,
and then they connect immediately.
I suppose I could let windows manage the card and
see if it improves.
There's none of this trouble with the Dell 1397
cards. It's not as if it's an unsolved problem in
computer science.
Apparently Intel can't write software, or doesn't
care.
