IPad 2 keeps dropping wifi since 8.1.2 just did factory reset to new still dropping

Question

MY ipad 2 drops the wifi signal 10 feet from the router starting immediately after 8.1.2 update. My iPhone 6 that I have not updated will get 2 bars wifi signal in the same spot my iPad used to get 2 bars and now has none since I updated to 8.1.2. I spoke to Apple and first we did everything on the list to help with this such as forget network, reset iPad and now I just did a factory reset and restored my iPad as new and it is exactly the same. Other devices not updated work fine. What's next? I hope there is a software update coming to fix this, we can't use the iPad effectively in the space it comes in because that room is very cold and not a social space...

Answer 1

It is not the router because we've had about 7 different devices work fine from much further away. My iPhone and mothers iPad, kindle, Apple TV, iPod and home computer work fine. My mothers iPad nor the other devices mentioned are not up to date with the 8.1.2 and all get two bars where mine used to also get two bars until I did the 8.1.2 update. It has to be related to the software as it worked great until the software download was complete and from that second on it drops the wifi when I walk further then ten feet from the router. It was instantly different after the update, I wish I could get the old IOS back somehow. I then have to walk back close to the router, go to settings select our wifi then sit in this room to use it...
