I have an early Galaxy Tab S Wifi/4G tablet and the WiFi has suddenly stopped working.
The symptoms are similar to several other posts reported in this community and other forums but I am yet to find a definitive answer as to what the cause is. My assumption is that the wireless radio on the motherboard has failed.
A few days ago, the WiFi started cycling round turning off and on continuously - it would stay on for say about 7-8 seconds and then turn off again. After about an hour it just failed completely. If you try and slide the Wi-Fi switch across in settings, it just stays grey and says 'turning on' - but never starts. Bluetooth also fails to work.
I've tried a factory reset and cleared the cache etc. The tablet has no physical damage (it is absolutely pristine) but is now rather useless.
My question - can someone confirm this is a motherboard issue? And if so, does anyone know the cost of Samsung UK fixing this? The device is out of warranty unfortunately.
