Hi again, I forgot to mention that those warning from mac80211 (the associated comments in the code are 'RC is busted' or 'uh huh?') seems to somehow disable completely the rate control: 'iw wlan0 link' gives 'tx bitrate:' with nothing after. Furthermore, I loose the network from time to time on reason 7. I went back to kernel 3.8.0: if there is enough traffic continuously, the link is stable but I loose it randomly when there is no traffic. I made more debug on the 3.8.0 kernel, the first warning correspond to the following test: (info->control.rates[i].idx) 15 >= (sband->n_bitrates) 12 Please tell me what test I can make to find the source of this problem.
From what I remember, that problem has been fixed. The correct code should be in 3.8.2 and in 3.9-rc1.
The firmware in all the cards that use the rtlwifi family of drivers its own rate control. The drivers do not pay any attention to any rate-setting calls from user space.
I also see reason 7 disconnects; however, with NetworkManager, the network is reconnects. If you are using ifup or similar method, it probably does not reconnect.
