im a new ubuntu user. I have decided to dual boot ubuntu and windows because i wanted to give ubuntu a try and maybe make it as my primary os. But im currently having problems with my wireless network because it only displays 2 bars and that its very slow (especially loading 2 or more tabs) compared to my windows, which doesn't have a problem with the wireless conection. Need help on this please thanks! :)

PS. Im really liking ubuntu so far, just having this bit of a problem.

Edit. I have ubuntu 14.04

itsfoss.com has some tips which helped speedup my wireless - I would ignore the part about WICD, as it does not seem to be supported currently, and does not totally integrate into Ubuntu 14.04.

A second post which also helped advised entering the following command into a terminal:

sudo apt-get install build-essential libssl-dev linux-headers-`uname -r` linux-firmware-nonfree

Please do:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
sudo modprobe -rfv ath9k
sudo modprobe -v ath9k

In your router change encryption to just wpa2 (CCMP)(AES) not (TKIP) if you have that option (TKIP) is known to slow the connection down.

Also you have two connections with the same name and are on the same channel, you need to remove the weakest one.

In network manager change your settings to match the screenshots. DNS SERVER IPV6

Make sure your ethernet connection and tethering is disconnected by unplugging the phone and ethernet cable, then reboot the computer before testing your connection speed.

Also remember distance and what the walls and floors are made of if you have more then one floor between the computer and router affect the signal and speed.
