iPhone 4 WEAK Wifi - GSM-Forum

adaseb · 03-29-2012, 10:10

I tried changing the screw, the metal black bracket, I even put the logic board into another frame and the wifi works, however wifi isn't as strong as it should be.

Works on my floor where my router is but doesn't work in the basement.

Any solutions to this?

Ok, i'm not sure if i will help you, cause you probably know about this. You said you changed the screw, but are you sure there was that little metal piece on the EMI SHIELD? Here's the photos for you to check. Once i had that problem, and i lost the little piece, so instead, i adapted a little piece from a screw.

Yes I checked that part, even changed it with another one but I get the same problem.

It has to be the logic board because in the same housing another iPhone 4 had perfect wifi reception.

Nothing looks missing on the board and the board was never water damaged or anything, only dropped.

Yes the coil is still there.

The WIFI is not low, maybe 50% of what it should be.

It works on the first level of my house. But doesn't work on the 2nd level or on the basement while other iPhone 4 do.

Its not the metal clip, or the housing. It has to be something on the logic board.

Unfortunately that didn't solve my problem.

All I know is the phone was dropped very badly where it cracked the LCD screen inside. Is there any chip that I should reflow or reball that might have microcracks?
