On Ubuntu, my internet speeds (which would normally be good) is very crappy and I can't find help anywhere. Please help! I have an HP Pavilion g7 1310-us and the type of wireless receiver I have is a Broadcom 802.11 a/b/g/n.

got this thing solved for me (well, I didn't myself, got the solution here) in a terminal, write:

echo "options iwlagn 11n_disable=1" | sudo tee /etc/modprobe.d/iwlagn.conf
sudo modprobe -rfv iwlagn
sudo modprobe iwlagn

hope this helps.


try the following commands

sudo ifconfig wlan0 down
sudo rmmod -f iwlagn
sudo modprobe iwlagn 11n_disable=1
sudo ifconfig wlan0 up

Try browsing again and if there is an improvement, make this change permanent by
loading this kernel module at boot with the 11n_disable option enabled. This would be done by modifying your /etc/modules file by the following:

echo "iwlagn 11_ndisable=1" | sudo tee -a /etc/modules

If that does not work then-

create an 'options' file:

gksu gedit /etc/modprobe.d/options.conf
and add the line

options iwlagn 11n_disable=1

Hope this will help.

When I put the first line in I got:" tee: etc/modprobe.d/iwlagn.conf: No such file or directory" – Excalisnake Apr 14 '12 at 14:07

Anyway I added "wl" in /etc/initram-fs/modules and executed update-initramfs -u. Seems that fixed the issue – user55370 Apr 17 '12 at 18:50
