Fixed slow wifi (n mode) on Lubuntu 11.10

I followed this guide.
In particular the second method worked for me.

2- Second Method:



This method involves forcing iwlagn to not use n, the commands will disable n on the device without making it a permanant change, check first if this work for you, if you notice that the speed improved then continue to make the change permanant. If this solution didn`t work for you, then reboot your computer to revert the chnages.


sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1


If you notice that the wifi speed improved, then make the change permanent :


sudo vi /etc/modprobe.d/iwlagn-disable11n.conf


and add this line to the file:

options iwlagn 11n_disable=1


save & quit
