Since updating ipad2 to ios 6 my wifi range has dropped and I cannot even connect when in next room to router. I have done a full factory reset with no improvement

1. Temporarily disable the Wi-Fi security (WEP/WPA/WPA2) and test connectivity. The Wi-Fi security may be causing the problem.

2. Also try using different channel e.g. 1, 6 or 11

3. Also try updating the router software.
