Wasn't one of the big things for 6.0.2 improved wifi? My wifi is worse since the update:
-my wifi turns off when I lock the screen for a long period of time, so no notifications get pushed during that time. Whenever I unlock my iPad, I get all my mail and other notifications pushed.

-it causes problems with my wifi at home. I don't know why, but there is a direct correlation between my iPad mini and the lag on my pc gaming. When I play my games, the ping is around 80 ms (wifi on my iPad is completely off). When I turn my wifi on, I get bumped up to 180 ms. I've done this several times, always yielding the same results.

Are these issues coming up for anyone else?

I was thinking about restoring my iPad to see if it will change anything, but I want to know if its just the 6.0.2 upgrade otherwise I won't even bother.
