This may or may not be of help however:
I haven't tried network manager, but I had heaps of trouble trying to
connect to a wireless network, and attempted all manner of stanza's
in /etc/network/interfaces without any success at all.
I finally tried wicd though I would have like to do it without that
front end.
But wicd didn't connect every time either, couldn't find the networks
available. Googled found I had to install python-urwid and then
it found the available networks and connection every time. Some bug in
the current version of wicd. That's the fix, and don't know why it
wasn't installed with the wicd packages. Maybe it was included but I
missed it.
Now I have to try to remember, because I'm not on that lappy. But in
the properties of wicd, I had to choose - preshared - network or
connection or something and add the name and also the passphrase. Any
other of the connections wouldn't connect with all the right ESSID and
passphrase. But your mileage may vary in this.
When I got this working I ticked the box: connect automatically. It
does, it works at least.
I'm using an up to date updated Debian testing - a wireless dongle with
package firmware-ralink on an Acer laptop and what else? It works with
both 32 kernel and 38 kernel, but the 38 kernel has always locked up at
various unknown times, even before I got the wireless connection
working.
Firmware-atheros didn't work, and that's what the lappy has inbuilt.
That's about it.
Anyway, hope that helps.
