Ubuntu 11.10’s WiFi crashes my router
No seriously, it does. Whenever it makes a connection to the router it causes it to enter some bad state wherein it refuses to allow any connections to occur. This also has the effect of booting all other machines from the network. Apparently I’m not the only one to have this problem either.
I did manage to find a bit of a work around though:
- Set your wireless router to Mixed B/G mode only (yes I know, you lose out on N by doing this…)
- Enter the following into a terminal:
echo "options iwlagn 11n_disable=1" | tee /etc/modprobe.d/iwlagn.confg
sudo modprobe -rf iwlagn
sudo modprobe -v iwlagn
sudo service network-manager restart
- Maybe reboot?
I’ve also heard of some people getting it to work by enabling this instead of disabling it. To do so simply change the 11n_disable=1 line above to 11n_disable=0.
Hopefully they will have this annoying bug fixed soon.
Previously I was running KDE 4.3.3 on top of Fedora 11 (for the first experiment) and KDE 4.6.5 on top of Gentoo (for the second experiment).
