Comment 8 for bug 344022

To be more specific, my working Intrepid install on eeepc 901 has a "stock" Ubuntu with intrepid-proposed and "Proprietary drivers for devices (restricted)" enabled in Synaptic Software Sources.

I show the Adam McDaniel <email address hidden> as the maintainer of the installed driver:
apt-cache policy rt2860-dkms
rt2860-dkms:
  Installed: 1.7.1.1
  Candidate: 1.7.1.1
  Version table:
 *** 1.7.1.1 0

In my working configuration I have the following installed:

  Version table:

I'm currently on 2.6.27-14-generic

I've been using this (with periodic updates) for months with no problems against a D-Link DIR-655 Hardware Version A3 Firmware Version 1.20.

The Jaunty Live CD Beta fails on the same hardware.
