I've set up two wifi access points to give good access in a house. They are both connected via cable to the same switch and are configured with identical ssid and identical encryption type and key. APs are made by different manufacturers. No wds is used. Quite often it seems like mobile phones (Samsung) loses connection to the network. Phones are set to automatically connect to the ap with the best signal. Turning wifi off and on brings the connection up again, but it is a bit anoying... Any ideas how to fix?
