iPhone4 losing wifi signal,
At me such problem after repair of the top button , wifi the receiver began to accept very badly a signal on distance of 3 meters from a router it absolutely dont work. Replacement wifi the module hasn't helped I think a problem in motherboard. What I can make? (Except replacement Motherboard)
this is a link to previous answer that has several links to the same problem.. see if any of the answers help. If they do then please mark up those answers and not this one. As this is the same problem I think we should merge it with the others.http://www.ifixit.com/Answers/View/53108...
Bradley's post and photos are the best at illustrating what the issue is with low WIFI, Bluetooth and I think GPS as well signals. The little linking piece under the top center of the top EMI shield comes loose and separates from the EMI shield. If it is not put properly in place or it is not put back in at all,(I wondered where it went too and looked and looked until I found Bradley's post) the WIFI, et al signals will be weak. This needs to be included in the appropriate place in the Guides that it applies too. There are many posts on weak WIFI, et al signals here. It is not a mystery once you understand Bradley's excellent post.
