The mailing list for NetworkManager is networkmanager-list at gnome.org,
the website is http://www.gnome.org/projects/NetworkManager/

I believe this list is about the kernel part of wireless support.  If
you track the issue to the kernel, then please post here.  Don't forget
the kernel messages and more details about the kernel.

If you want a basic connection with WEP, you can try to use iwconfig.
Please make sure to set the channel, the AP (BSSID) and the ESSID.

You can also run wpa_supplicant from the command line.  wpa_supplicant
would find the AP for you.

Here's the same rt2570 device using the ifconfig commands. I was
trying to get NetworkManager running on it in case it was doing
something that I wasn't doing manually. Some is not quite right with
the WEP exchange.

It would be interesting to look at the iwconfig output at this point.

I think I've located what the problem is. NetworkManager was hanging
around as a deamon and changing my encryption settings improperly
probably because of the NULL gobject problem. I fixed my system to not
run NM, rebooted and now I can connect.

d80211 selects ARC4. ECB is selected too if you have Linville's last update.

I think I've located what the problem is. NetworkManager was hanging
around as a deamon and changing my encryption settings improperly
(turning off WEP) probably because of the NULL gobject problem. I
fixed my system to not run NM, rebooted and now I can connect. I'll
just get rid of NM since it is not needed for my application. Turning
off encryption gave me enough clues to blame NM.
