This is on Ubuntu 12.04.1 live USB, 32bit, kernel 3.2.0-29-generic-pae.
I've reloaded the module with swenc=1 and debug=5 options (modprobe
rtl8192cu swenc=1 debug=5), hopefully that will provide more usefull
info.
** Description changed:
The networks around are visible, but when trying to connect, the NM
repeatedly asks for the password. Connecting to an open network fails as
well.
