Can I force a wifi connection retry after x minutes? The Wifi SSID in my home is the default SSID of the used router. (I have no means to change it unfortunately)
The problem is, if i travel around my city, my android phone inevitably finds a network with the same SSID but the password doesnt match. Since then the network is stuck in "Authentification failed" until i manually force a reconnect.

Is there a way to force my phone to retry connection attempts to known networks e.g. every 5 minutes?
There are numerous applications on Google play. I had similar problem a couple of months ago. I used application named WiFi reconnect as I recall.
