Chosen Solution
Hello, 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.
Ok, let’s try to sort it out a little bit. You wrote about “mywi” - did you actually connect with the iPhone ? (especially - what distance did you have between the device you connected with the iPhone? - and of course - did you try to connect with the router - while you’re standing beside the router?) The first link didn’t work - the second one isn’t the Wi-Fi antenna The Wi-Fi antenna looks like that: the connector is number 6 - so check the connection and of course check the contacts. Also, if you bent the connector to much, it could be broken and the result would be no or bad Wi-Fi reception. Update I searched my sources a little bit and found a solution posted in a gsm forum by “MPhoneClinic” (the mobile phone clinic from melbourne/australia) I searched for a larger picture of the PCB and marked the part that you have to change
So, the good thing is - you know what’s defective. The bad thing is - where to get the part and depending on the tools/skills you have, how to replace it. But maybe you will find a good repair shop in your area who is able to fix it for you.
Hi! i was having this problem in my 3g and solved it by doing the following.. install bootlace, install idroid, boot in idroid, turn on the wifi - power off idroid boot on ios 4.x.. wifi working.. i tryed everithing else except for the hardware solution and nothing worked (except for the freezer thing.. that worked for some minutes).. i have wifi working for 3 days now..
The following clever little fix worked for me. I think what happens is the heat liquefies a broken solder point enough to reestablish contact. (I used the hair dryer option): http://www.google.com/url?sa=t&source=we…

The light bulb theory apple releases software updates that have hidden agenda to phase out older models forces us to upgrade to newer products. I’ve had 7 different 3 gs with the same problem that worked fine prior to os 3 series but after any is higher then that series wifi did not work I find that a bit odd Update I meant 3 g model iPhones not “3gs
i have the same problem in my wi-fi my iphone 3gs is not searching any wi-fi network i have checked it on 2 or 3 wi-fi connections but it is not searching any of them plz help me if someone can…
i doubt anyone can answer this but… my iphone 3gs was restored to the whited00r 3.1.3 firmware and now the 3g dosnt work help please
it might look crazy, but I put my iPhone 3g in the freezer for 30 minutes and the Wi-Fi is working, I had tried everything from re setting all that staff no work.
well, If you want to have some minutes of wifi put your iphone into the fridge (cooler) near your frozen things… and in 10-15 min you take it away… you will get maybe 5 min of correct working of the wifi….
