Recently, the wireless started to do a tantrum, disconnecting frequently accompanied with a nice ABRT:
Package: kernel
Latest Crash: Sun January 30, 2011 22:03:52
Command: not_applicable
Reason: WARNING: at net / wireless / core.c: 633 wdev_cleanup_work +0 x52/0xbd [cfg80211] ()
On the web it seems the problem is not so rare, but despite this, the bug has not yet been eliminated, at least through the repository.
The most annoying thing is that apparently when the problem occurs, the only solution right now seems to reboot.
With these simple steps you can instead restore functionality (but not stability) of the wireless :
# # remove the module from the kernel driver
$ sudo modprobe-r iwlagn
# # reload the driver module in kernel
$ sudo modprobe iwlagn
The next steps may not be necessary
# # enable the wireless card
$ sudo ifconfig wlan0 up
# # searches for networks
$ sudo iwlist wlan0 scan
# # restart network manager
$ sudo service NetworkManager restart
# # check the status of network manager
$ nmcli-nm p
Here The bugtracking, and here its proposed solution, waiting for the 2.6.37 kernel, hoping that it is more stable from this point of view .
