Title: wifi fails at (re)connecting after a while Status in “network-manager” package in Ubuntu: New Bug description: CANNOT reproduce, happens occasionnaly (but forces me to reboot) sometimes, the wifi just stops. It seems to happens when I download much, and the wifi seems to disconnect. Then, its starts connecting over all the network it knows, and fails at all. I can connect on my personnal wifi with my android smartphone, but the OS cannot. Sometimes I cannot event deactivate the WIFI/network by unchecking network or WIFI in the contextual menu in network menu (top right, next to the sound) When I do services networking restart, nothing happens but a "stop: Unknown instance: " then I do a service network-manager restart. The daemon rstarts, and stops looking for all networks. But fails at finding ANY network. Then I need to restart my laptop, which is the last-resource Windows solution and is a sign of failure. What I deduce: - either cannot support a heavy load, or a high number of data sent. - "loses" somehow the driver ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: network-manager 0.9.4.0-0ubuntu4.1 ProcVersionSignature: Ubuntu 3.2.0-26.41-generic 3.2.19 Uname: Linux 3.2.0-26-generic x86_64 NonfreeKernelModules: nvidia wl ApportVersion: 2.0.1-0ubuntu10 Architecture: amd64 CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
