Bgscan should be enabled. At home we have two n (and 2 g) wifi networks. When powering off one ap it connects to the other (in addition to using lagg to failover from ethernet to wifi and back). Your wpa_supplicant should contain each ssid you intend to use. A wildcard can be used for open networks. It's a while since I've tested this functionality but I can test again when I get home tonight. -- Pardon the typos and autocorrect, small keyboard in use.
