On certain wireless routers, I was getting the dreaded "wlan0: deauthenticating from … by local choice", resulting in constant disconnects (every 30 seconds or less). I tried a whole bunch of options (disabling 11n, disabling hw scanning etc) and the only thing that eventually worked was disabling ipv6.
sudo gedit /etc/sysctl.conf #Add these lines at the end: net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1 #Save the file. sudo sysctl -p
Worked rightaway without reboot.
