Very weak wifi signal after housing replacement

Check all screws, screw holes, logic board holding brackets and antenna RF cable sockets on the top half of the phone.

I have fixed this problem today at the one I have replaced.

I removed the WiFi module and losed all screws in top, lose on the motherboard and remove simtray so I could bend it a little up.

Then took a knife and scratched all the threads of the screws in top then put it all back.

Went from finding my WiFi standing 2meters away, to finding all my neighbor's WiFi and full on almost all of them!

Hi, it's possible that the new housing may be causing the issue, as they are probably not the same standard as the original.

You could try the logic board in a known working housing and see if that resolves it, if it does then it's the housing, if not, it may be logic board damage. :-)

Hi I just figured out the problem. It's because of the abscence of the thin copper panel which is located under the wifi module. Basically when you or novices replace their phone's back plate, they might not think about the panel of which it magnifies the signal to the module. However, OEM companies dont offer the parts together. Maybe because of price, workforces or profits.. There are a few solutions.. 1. Take it to the repair shop. 2. This is my recommendation, and I also solved wifi problems through this. So, you need the original plate. At the Left upper corner, you can see the two black circle shape spongee. Underneath of it, there are copper plates which I've mentioned above. Just carefully take off with knife (you can easily take off from the plate.)

Then attach it to the new plate exactly same place!!! You can see the astonishing full wifi connection after assemble it. I hope this can help alot of people!! Sorry for my poor English! (Im a Korean :) ) Any question would be my pleasure XD

I replaced both my iphone 6 and 6 plus with a green color back housing and both my wifi are very weak. I believe it is the aftermarket back housing bc prior to this replacement everything worked great. Don't sacrifice looks for functionality. Its not worth it. Changing mine back to oem once i have the time

Bennyb123 was the problem solved? if yes how?

Dudes you likely got the one small flex cable on the back of MB disconnected.There are 4 connections they make trick on you looking like connected but at least one of them is do not!Have a look into..

I have the solution to the fix. At the top left of your motherboard you see all those screw spot that kind of form into a circle. You need to make sure when you transfer those screws when you transfer your motherboard to the new housing, completely correct, and make sure your not losing any screws because if not all, most of those screws have to do with reception signal, like I always said, if it came with the screws then it was meant to be there, don't get lazy halfway through the fix. Good luck.

Check the wifi flex cable at the back of the mother board. This is either loose or needs replacement.

Thanks a lot for all your suggestion. It was very helpfull for me. My iPhone 6 is now working with full signal strength.

I changed my display earlier 3 days and wifi signal become very weak and drops. I went to repair shop and asked them for replacement. Tried many different dispaly all works good as I get full strength signal when the display is connect, but as soon as display is fited with screws the same issue happens. What to do?

This post is the first to show on google so i’ll post my issue with weak wifi after a housing replacement using non OEM. The signal was very weak despite only being a few meters away from the router, I checked all the jumpers and everything was ok, the wifi module looked good so I didn’t suspect this.

Just to be sure I removed the module to re-seat the connections and surprise surprise one of the connection plugs fell off, maybe damage during the removal of the motherboard. I placed a new one on and have full strength using a non oem housing.

Hope this helps
