This is simple way to fix iPad problem, cannot connect to Wifi Access Point. First, create separate Wifi network names to identify each band. This can be done easily by appending one or more characters to the current network name. for example: Add an NA to the 802.11n network name and a G1 to the 802.11b/g network name. Ensure that both networks use the same security type (WPA, WPA2, WEP and so on). Update the Wifi router firmware if it’s not up to date. If the issue persists, reset the iPad network settings using Settings -> General -> Reset -> Reset Network Settings.
