[Bug 793328] Re: network-manager drops wifi connection and fails to reconnect

 

Same issue, start happening week or two ago. Just drops connections,
sometimes after 5 minutes, sometimes after few hours, and can't connect
until full system restart. Few times a day, it's really annoying :(

Tried with 3 different AP, and 2 wificard (my laptop's internal and an
usb wifi)

Title:
  network-manager drops wifi connection and fails to reconnect

Status in “network-manager” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: network-manager

  Using Ubuntu 11.04 (Natty) with Unity, wifi connection is reliably
  lost after some time. Network-manager fails to re-establish the
  connection; nm-applet icon spins interminably. The applet menu shows
  the access point as "connected", but no connection through to internet
  is available. Disconnect/reconnect using menu fails. Network-manager
  requests WEP pass after long delay, but still does not connect. Only
  solution is to re-start Natty.

  Same hardware, same connection - no problem with maverick, no problem
  with oneiric.
