Source of Reason 7 disconnects

[Larry Finger]

Emmanuel and Johannes,

I am trying to fix "Reason: 7=CLASS3_FRAME_FROM_NONASSOC_STA" disconnections for 
the Realtek drivers. When I did a search for similar examples from other 
drivers, I found some forum entries for the same disconnects happening on Intel 
7260 hardware. It appears that the problem was fixed in the 3.16 timeframe. I 
looked through the iwlwifi commits from that time, but I failed to see any 
patches that appeared to be appropriate.

Do either of you happen to remember what was needed to fix the problem? So far, 
I have determined that disabling power save helps, but it is not the complete 
solution.

Thanks,

Larry

Thanks for the reply. As far as I can tell, we don't get disconnected without 
knowing about it, but only when the solution is found will we know for sure. 
Thus far, I do not have any over-the-air captures to investigate.

Thanks again,

Larry
