Vasilis Tsiligiannis a4ed68fbe4 madwifi.sh channel fix
In the madwifi.sh there is to read "only need to change freq band and channel on the first vif". This is wrong. For example if you create a new Ad-Hoc network and an AP interface, the channel is reseted to 1, regardless of the UCI setting. So remove this wrong code.
