Wifi and GPS not working after I disassembled it.

It all has to do with the top IEM connector cover plate (the one above all the connections). Either that was not put back on right or there is something wrong with that. Clean the connections and make sure its assembled right. That is the location of the WiFi antenna. Hope that helps.

i wanna share how i fixed mine with tin foil!!

take off the wifi cover,

take some tin foil, or (aluminium foil) if your from the US

Fold the tin foil so you have a tiny square so its about 1.5mm - 2mm thick

stab a hole in the middle of the square with a needle, cutt around the needle so the square is very small, then all you do is place the long screw in the top of the wifi cover and before screwing it down to the iphone place the DIY tinfoil washer or the screw behind the wifi cover , Viola!! worked for me hope it helps out anyone else :)

There has to be more involved with this rather than simply screwing in a screw at the top of the EMI for this to be resolved. It would be nice to hear from the OP in regards to results...

I, too, disassembled my phone and noticed that I don't have the silver grommet on the plate where the longer screw goes in, so I'm assuming it came off without my knowledge in the teardown/reassembly process. I ordered a new part to see if this would be a fix.

I don't understand why all of the parts dealers, this site included, are identifying the part attached to the speaker as the WIFI antenna if this top location is actually for wifi then. Seems like a new one would fix this issue, but it does not.

Your link doesn't show two screws, Jeremy. It just shows the assumed location of a gold connector and a "likely" 2.4 GHz connector pad...Tells me nothing.

Not trying to be a troll, just frustrated by the lack of completeness on repair sites. Seems like the OPs never bother posting results after someone marks the issue as answered, too...

Had the same issue and fixed it with the pics from the site above. Turns out the metal spacer/washer on the EMI cover fell off on when I swapped my LCD. Same washer for the long bolt they are talking about above. Put that back in with the help of the pics above and now back in business.

hi i have no wifi on my iphone 4 i have had a look under the emi cover and looking at the image at the top of this page, i dont see a gold connector to the antenna. does anyone have any clear pictures on the screws and washers.

Hi Ellis, can u send a picture of what you did??

thank you

i did what ellis goward said and it work, theirs a metal piece in the edge on the cover were the long screws goes, and my was missing.

I think I have the same problem with my iPhone 4s, poor wifi after screen replacement. Is the solution the same as for the iPhone 4? Do the EMI shield and the wifi antenna look alike?

Hi can someone help me. I have No wifi at all. I have replaced the EMI shield but I am still getting nothing. The wifi won't even turn on to start searching. Is this the only connection for the wifi?
