It always tries to connect to a network I very seldom use.
Incidentally, where does it store "profiles" or indeed any information?
Is it available to the user?

Thanks, I'll study that.

I'm using an Orinoco PCMCIA Gold Card on my laptop,
and Linksys WRT54GL as an Access Point on my desktop.
I might say that this works perfectly under Windows.
Sadly, I find Linux WiFi rather a mess, to put it mildly.
There seem to be files and programs all over the place
which might or might not have some relevance.

Thanks, I tried that but unfortunately it seemed to have
a disastrous effect on NM.
Basically, my WEP key was never accepted.
(It does not accept the WEP key on my old network either,
which works perfectly with Windows.)
What is more, after failing to accept my key
NM said it could not find any wireless networks,
where previously it saw two of them.
Has anyone else had problems getting NM to accept a WEP key?
I'm pretty critical of NetworkManager at the moment.
It seems to me it tries to be too clever
(a common fault with Linux applications)
instead of being satisfied to do one thing, and do that properly,
as Ken Thompson recommended.
I'd be more than happy if NM worked well with WiFi;
I'm perfectly happy to use other programs for Bluetooth or Ethernet.
