IPhone 4S doesn't stay connected to wifi

Question

For the last few months my iphone drops the wifi single.  Other devices in the same
room have no problem, including my iPad.  What can I do to fix this. Mon another note,
my battery life ***** also lately.

Answer 1

i have a similar problem except i've a 3GS.  i took the phone to the "Genius Bar" and the "Geniuses" there did nothing more than clean out the lint that had accumulated over the past three years.
here's the link to my thread:  https://discussions.apple.com/thread/3947285
I've done everything possible with the phone and my router at home (though, as you can tell from reading what i've done, anything related to my router at home is moot because th eissue persists anywhere i go...)  all i can think is that it's a OS issue some how.  I may try to wipe and install an older OS or jail break it to see what happens.
My bets are on what people have said to me though in passing:  this is Apple's way of making people want to move onto the iPhive (name trademarked by me!) due to frustrations with their iPhour or iPhthree (that doesn't work so well does it...).
