Team, I am interested in testing adhoc network using high power n-radios from Ubiquiti. As of now I don't think IBSS mode is fully working on ath9k but please correct me if I am missing something.
Any help in this direction is appreciated. And of course I am more than willing to collect more traces for debugging this problem.
