Recently mac80211 was changed to send nullfunc instead of probe request for connection monitoring. These nullfunc data frames are being sent at higer rates and also as aggregated ones. This could probably delays the nullfunc_ack so the connection is getting disconnected as max retries reached. In order to improve the connectivity send the nullfunc at lower rate.
