I think Ubuntu has a rt2x00 update in backports that should resolve your problem as well.[/quote2f6tojz8]
Thanks, I'll try that now
[quote2f6tojz8]Otherwise using the legacy rt2570 should also work.[/quote2f6tojz8]
Which download would that be?
why can't I connect to a WPA encrypted network with the rt2570 driver from the CVS[/quotetszncaib]Inability to handle AES - CCMP - encryption was a long standing problem with the legacy rt2570 driver, which is what kept WPA encryption from working when that was specified - although I believe TKIP encryption was OK. A fix that handles CCMP encryption - at least for adhoc operation - was put into CVS on 5/4/08. So if you download the latest source tarball and build, WPA with AES should now work for you.
If it does not, please compile and run with debug enabled and post the log here.
(edit) at least for WPAPSK.
