I'm having kind of a weak signal on Ubuntu, about 2 bars (I have a laptop), when i go on windows it really gets quicker (5 bars). What may cause this? My wifi worked as soon as I installed Ubuntu so i did not install a network driver. According to connection informations, I am using the ath9k drivers. I can provide more informations if needed. My wifi adaptor is a Atheros® WB225 (802.11b/g/n) and my bluetooth is set off. I also use a 2,4GHz wireless mouse which I have been told may cause interference? Anyway how can i fix this problem please?

Here are my lspci and lsmod.

Try a speedtest (download and upload) is the speed the same? and does the signal have the same reach (distance away from modem)? I have that, the signal looks lower, but is the same speed/reach.

My speedtests are always good with my laptop, better than my cabled computer actually. Just wondering why i have 2 bars/5 instead of max. –  D3s7 Sep 23 '12 at 2:35

they are saying sudo apt-get install linux-backports-modules-karmic followed by sudo apt-get install linux-backports-modules-wireless-karmic-generic I don't know if it will work, but it is worth a try –  Mark Compier Sep 23 '12 at 3:44
    
Both gives a impossible to find package error. –  D3s7 Sep 23 '12 at 3:46
