Answer to: Very poor Wifi Range (advanced)I had this problem too and I figured this out and fixed my wifi signal...take a look at the speaker of the iPhone. You will noticed a bunch of little hooks located on the north side of the speaker. Make sure that those little hooks go under the frame(that's the metal under where the battery is seated, then screw the speaker down and make sure no hooks lift. Also take a look at the wifi antenna, there is a piece where an abnormally long screw goes, make sure there is a metal clip there! If you don't see that piece than you lost it while you we're fixing the iPhone. That metal piece is required for good signal.
