Title:
  wireless connection drops

Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  I'm using Ubuntu 12.10 (fully updated) and the wireless connection
  keeps dropping.  It appears to be connected in Network Manager but I'm
  unable to reach any web pages or the admin page of my router.

  Clicking on the network manager icon and selecting my network re-
  establishes the connection which is fine for about half an hour then
  it drops again.
