Public bug reported:
Binary package hint: linux-image
I have an Edimax EW-7711UAN wireless adapter which should be supported
by the rt2870sta driver. In maverick the adapter is recognised and an
interface is created, however no traffic passes over the interface and
no access points can be seen.
The system is running a basic maverick i386 install with no updates
(since no network connection), except for linux-image-2.6.35-25-generic
since this contained the rt2870 module and I was hoping there might
already be a fix for this.
