Chosen Solution

Hey everyone, a few days ago I got my sisters old Iphone 4 to make it ready so that our dad can use it. While I was doing so I noticed that the battery was quite weak, so I ordered a new one and replaced it. Now I have a very weak WIFI signal. (The little problem is, that my sister can’t clearly remember whether the wifi was working before she stopped using the iphone or not… so that it could be an issue which dates back some time - however she thinks it worked just fine) Anyway, it’s the same phenomena that I have already read lots about (only 3 bars while being 50cm away from the router and no signal at all in the next room). Problem is that I only found threads with users who tried to replace their screen or tried to do some more serious repairs and in almost all cases the cause was the “wifi"screw (the long one), or the lost clip that is used to make contact when the “wifi"screw is tightened. Things is, as I said, I just replaced the battery - so that I shouldn’t have come into contact with critical areas. What I tried so far:

  1. rebooting the Iphone
  2. resetting and installing a new IOS (6.0.1)
  3. disassembling of the wifi-shield to check for that little contact everyone loses during their repair (as expected it is where it should be)
  4. cleaning the contacts
  5. using tinfoil to make contact between the long wifi screw and the frame(saw this here: http://www.beijingiphonerepair.com/fix/f… )
  6. talking to the little man in the phone, imploring him to repair it -.- However, every single one of my attempts was in vain. Help is greatly appreciated!! Seriously I am going nuts over this ; / What really is strange is that GPS and cellular data signals are working just fine. It’s really just the wifi signal.. I am about to give up on it(and probably would have done so long ago if it wouldn’t be for my old man.. cheers nico Update Ok, sorry for the long absent time - it took the part quite some time to arrive(the new speaker with the mounted antenna) I installed it right away, but nothing changed … so it was not the cellular antenna after all -.- well .. worth the try though! Any other ideas ?

The answer to your newest question is no, and I will look real hard at a answer to your problem today.

Have you considered interference? What is your router broadcasting? b?g?n?b/g/n? do you use a cordless landline on 2 Ghz or 5.4Ghz? A few settings tweaks are often all a poor wifi signal requires.

The answer to your wifi issue is 100% the battery connector is failing as like u I replaced all possible parts and found it to be this hope this helps ;)

Maybe this issue is your WLAN signal be weaken between your phone or NB, you can try to replace your WLAN or to paste “Perfecting Signals” on your WLAN Box for improve its quality of the WLAN signal. More detail info to see below link: http://utilityhome.blogspot.com/
