iPhone 3G wifi not working - solution
i have some news, for the people who's wifi is not working.
i tried many things and now have more concrete facts about this problem.
my wifi can't find any networks.
first i thought that the problem is the wifi antenna.
on ebay there are many "wifi antennas".
all the vendors tell that this antenna http://www.traderscity.com/board/userpix... handels the wifi. but its not.
i disconnected it at a phone where wifi was working.
after disconnecting wifi still worked, but gps was not working.
so the wifi antenna must be somewhere else.
i think that this part http://www.dealextreme.com/details.dx/sk... handels the wifi and the 3G.
i changed this part, but the phone was still not finding any networks.
so i thought, that the wifi chip on the logicboard maybe broken.
so i wanted to make another test and i installed the jailbroken app called "mywii".
with this app you can open a ad hoc network with your phone.
and it works.
so the wifi chip is not broken.
wifi 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 wifi chip.
i also tried to reset network settings, made a update and restore. but nothing works.
ok, lets 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 - if you bent the connector to much - the contacts could be broken and the result would be no or bad wi-fi reception.
if searched my sources a little bit and found a solution posted in a gsm forum by "MPhoneClinic" (the mobile phone clinic from melbourne/austr
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 whats defect - 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
