iPhone 3G Wi-Fi Not Working - Solution
I have some news for the people whose Wi-Fi is not working.
I tried many things and now have more concrete facts about this problem.
My Wi-Fi can't find any networks.
First, I thought that the problem was the Wi-Fi antenna.
On eBay there are many "Wi-Fi antennas". All the vendors tell that this antenna http://www.traderscity.com/board/userpix... handles the Wi-Fi, but it is not the right one.
I disconnected the cable mentioned above and Wi-Fi was still working. Only the GPS stopped working, so the Wi-Fi antenna must be somewhere else.
I think that this part http://www.dealextreme.com/details.dx/sk... handles the Wi-Fi and the 3G. I changed the part, but the phone was still not finding any networks so I thought that the Wi-Fi chip on the logic board may be broken.
I wanted to make another test so I installed the jailbroken app called "mywii". With this app you can open a ad hoc network with your phone. The app works, so the Wi-Fi chip is not broken.
In conclusion, the Wi-Fi antenna and chip are working fine, but phone is not finding any networks. This is very strange. I have no idea what the problem can be, but its not the antenna and not the Wi-Fi chip.
I also tried resetting network settings, as well as updating and restoring the phone, but nothing works.
