One fix (commit a9b89e2) has already been applied, and it helped, but the maximum RX speed would still drop to 1 Mbps. As in the previous fix, the initial gain was determined to be the problem; however, the problem arises from a setting of the gain when scans are started. Driver rtl8192de also has the same code structure - this one is fixed as well. Reported-and-Tested-by: Ivan Pesin Signed-off-by: Larry Finger Cc: Stable Signed-off-by: John W.
