I have a strange problem.
My WiiU loses connection to my router every time i turn it off and back on.
The only way to get the connection back is to go the router settings and change anything. The channel, password or type, anything that relates to the wireless.
Once i do this, i can test the same connection settings and it connects fine.
All my other devices have no problems with my router. The WiiU has sufficient signal and runs fine once i do this.
