At initial set up I connect to my home network. This works absolutely fine. When I set the tablet to connect to my tethering hotspot on my S4 that is when problems occur. It connects initially but then shows disabled. The same now happens with the home network. The home network is via a HH5 which has both 2.4GHz & 5GHz. enabled. Telling the device to forget each of the AP's and reconnecting them does not work. Other devices (W7 PC's, the telly & another S4 ) can connect to my tethering hotspot without any problem.
