It’s been a while since I posted hardware fixes and solutions. Here’s one of the most common issue affecting the iPhone 4 – weak WiFi signal, and this solution will take less than 5 minutes.
My older post on fixing iPhone 4’s audio compiler chip issue proves to be popular and many were able to fix it themselves. Good job guys! Anyway, the above photo shows a WiFi signal within my work area. We actually have 2 WiFi routers setup, but obviously it’s not picking up the other one.
Warning: Proceed with caution. I am not responsible for any potential damage this may cause to your iPhone.
First of all, remove the back cover of your iPhone 4. As usual, check YouTube or iFixit.com for tutorials. Switch off your iPhone. Before you proceed with this repair, be sure to check that screws for mounting the logic board are not missing. The same issue can be fixed with by putting in or replacing them with the correct screws.
With a soldering gun, soldering iron, a wire and steady hands, simply make a jumper as shown in the photo above. Put on the back cover.
What do you know? Second WiFi router is now detected, and even the signal is showing full strength! Look at the time stamp, it only took 3 minutes!
Good luck and as usual, don’t forget to leave your comments below. We can also fix other hardware related issue, see here.
