Hello all, am having difficulty with my iPad 2, 64gb Wi-Fi, version 4.3.3. It started with the machine having difficulty seeing a WiFi signal (although I was in the same room with the router) then will only give me a "No Wi-Fi". It will not allow me to turn WiFi on or off (although Airplane mode is functional) and Bluetooth keeps searching even when right next to my MacBook (with Bluetooth turned on). So far I have re-booted the iPad, re-booted the router and modem, "Reset Network Settings" on the iPad, "Reset All Settings" on the iPad, and restored the iPad through iTunes. No joy. Before I reformat the iPad, has anyone seen this before and any suggestions? Thanks.
