Today, our driver > may be the only one having this problem (which I've never really heard > about?), but is it always going to be? honestly I have seen 5GHz problems with our driver multiple times. I always ended up disabling 5GHz support in the AP since I rarely have time to debug this. It only happens after long time of operation for me, but was like super annoying all the time. And I had similar issues with N support. I would personally be fine with a global debugfs option within cfg80211 to disable it.
