The correct rate scale information should be updated only in ieee80211_rx_bss_info function where beacon is parsed. Because of coding error the rate info was left untouched. If a beacon has triggered the connection the rate remined 1Mbps. This patch fixes this coding error Signed-off-by: Tomas Winkler Cc: Vladimir Koutny Signed-off-by: John W.
