Hey guys, I bought a used 3g and everything seems to work perfectly well except that it doesn't detect wifi. I've tried just about everything e.g. reseting network settings, airplane mode on and off, reseting all settings, restoring via iTunes, etc. Long story short as you can probably guess non of these things worked.

To make it clear, its not that I can't connect to a specific network, its just that the phone doesn't detect any networks (there should be atleast 4 options at my house alone from mine and my neighbors). My question is this, is there anything else I can do short of replacing the wifi antenna from inside the phone? My last resort is to try to replace it and risk breaking it, but is this worth the risk? I should have an extra one laying around from an iPhone that I took apart previously (and broke coincidentally). Some help/ reassurance/ a good tutorial would be appreciated. Thanks in advance!

P.S. no it doesn't have warranty anymore...if only.
 
what firmware you running
Settings > General > About and scroll down

are you jailbroken?

are you jailbroken?

I'm running 4.0, basically I bought the phone, tried to open up wifi so I could jailbreak it, realized it doesn't detect jailbreak, used 3g to jailbreak, saved shsh, restored/upgraded to 4.1 where wifi still didn't work, downgraded back to 4.0 and jailbreaked again.

Short answer, I'm on 4.0 & I am jailbroken, however wifi didn't work even before this. Thanks.
 
if you used Redsnowto jailbreak; go into cydia and download wififofum. You will need this to access wifi networks :mad:
minor inconvenience

Well thats impossible since I can't detect wifi. Also I used jailbreakme.com
 
give me a sec I will look at my notes to see what I did for my friend.

I just installed wififofum, it still doesn't detect any wifi networks, I guess it has to be a hardware problem. Might try to operate tomorrow.
 
sorry my response is so freaking slow. I picked up a mini the other day and I am still trying to navigate my way around.

do you recall having wifi when you loaded a GM 4.1 (non-jailbroken)?

Nope, since I bought it earlier today it defiantly hasn't detected wifi, even non jailbroken on 4.0 and non jailbroken on 4.1.
 
can you looking in the about page again and see if the MAC address is registering?
"If it says NA or 00:00:00:00:00 this article will provide the possible resolutions.

seems to be a popular issue

I have to go to work but will try to follow this thread while I am there

Thanks, that article pretty much confirmed that I'll have to repair. I'm wondering, is the wifi antenna the only thing that can be stopping it from getting a signal? I don't want to take the whole phone apart at the risk of breaking it, change the antenna, put everything back together, and then decode that it wasn't the wifi chip but some other damn part. Oh well, the say in Russian nor risk no champagne, thanks for the help, I'll let you know how it goes!
