The wifi used to work but has gradually deteriorated. It started to take longer to connect now it is connecting then obtaining IP address, then authenticating and then just disconnecting. The tablet states network is 'disabled, secured with WPA/WPA2 PSK'. This also happens in free wifi hotspots. It will just no longer connect. Any suggestions. Bought this on Ebay, no joy from the seller. Can I send it back to Gome as it is under 1 year. It is not the router (3Mifi) as my mobile phone works on it.
