iPhone 3G Wi-Fi Not Working - 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.

I made another test:

i disconnected the connector nr. 6 and startet "mywii.

i connected my phone with my mac and it worked fine.

also a distance of 4 meters, didn't change anything. (without the antenna on connector 6.)

Then i put my phone directly near the router (with and without the antenna on connector 6) but the phone doesn't find any network.

that's because i think, that the antenna on connector 6 isn't the wifi antenna.

but why can i connect the phone by using "mywii".

and when i search for a network my phone doesn't find any.

very stange problem.

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

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....
