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:
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
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.confand add the line
options iwlagn 11n_disable=1
Hope this will help.
