Some 5GHz wifi interfaces, especially in Tri-band routers, can't use channel 36. In these cases, the default configuration for 5GHz interfaces, once enabled, doesn't work. This patch selects the first non-disabled channel for 5GHz interfaces. Signed-off-by: Davide Fioravanti <pantanastyle@gmail.com>
