I have just installed ubuntu on the mentioned notebook but only Channel 1-11 are enabled by default. I cannot find how to change country code to EU to use channel 1-13.
Waiting your reply
i just installed ubuntu 10.04 on my computer, and tried to airodump, but noticed that its stuck on 11th channel, when i specified only channel 6 during scan, it gave me hosts from channel 6 and 11, but then i ran aireplay-ng and it runs on 11th channel as well, even when i put my card into monitor mode with a specific channel option. btw my chipset is AR9285 with ath9k driver.
I have been setting up my Mythbuntu box for a few weeks now and had been struggling with the Channel setup. But after some time reading up about SQL i used this script which i modified from the mythtv wiki for a freesat install.
