I have a client with a big house,
Almost every room has an airport extreme/ airport Express with the same SSID and automatic channel.
when you go from room to room, the iPhone automatically changes from one AP to the one with better signal.
But, I am facing a strange problem, almost every morning, this client goes into his kitchen (where 4G signal is not available and his mobile goes to 3G which almost dosent work), and the iPhone cannot find any Wifi SSDi, the airport express is one meter away and has the green status LED, so, he turn off and on the wifi, and not WIFI appears..... I cannot find a way to resolve a use, can someone point me to the right direction?, he was all the iPhone/airport updates
