I've got a problem when I try to set up a wireless connection to my university's network. I used a howto (can't say which one since i can't post urls because I'm new, but google for "vu wlan howto" and it's the first match) to try and set it up, and as far as I can tell, that all works fine.
However, when starting xsupplicant it hangs and doesn't authenticate. Together with a classmate we figured out that it may be because the university's network is provided at channel 6, while my network card tries to connect through channel 11.
However, the ipw2100 faq states that:
2.2. IPW2100 - Why won't iwconfig <interface> channel X set
This command only works within monitor mode. If you would like to use monitor mode, then set:
% iwconfig eth1 mode monitor
% iwconfig eth1 channel X
I have of course tried that, but it seems that monitor mode means that it only receives signals, and doesn't transmit any. Anyway, it doesn't work.
Is there a workaround to change to channel 6 while in managed mode? I vaguely remember reading something about being able to set the channel when loading the drivers. Could that be true, and if so, how do I do that? (I'm kinda new to this whole linux thing ;) ) Or do I just have to wait until the driver implements this feature?
Finally, some iw* commands:
# iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

I'll be at the university the next few hours, so if you need more information I can probably provide you with it fast.
Thanks for any help!
