Iphone 3G "No Wifi" Greyed Out Wifi Settings Option
« on: July 02, 2014, 06:54:32 AM »
My iPhone 3G has no Wifi. It says in Settings (where I should be able to enable Wifi) 'No Wifi' in grey color.
I don't even get to open the Wifi section.
Is there an alternative way to fix the problem rather than replace the Wifi hardware ?

Have you tried to see if the setting is greyed out on the stock version of IOS and try a restore anyway as it may fix your issue.

Could you go to settings -> General -> About
and then could you post the Modem firmware here.

You could try putting it in the fridge for a few hours a well

What iOS version is this?  If you do have a baseband version though, and are on stock iOS, I would say this is a hardware issue :(

Putting the iPhone in the fridge is not a permanent or good solution. It may work, for like 5 minutes or maybe even a day, but it is bad for the hardware.

I'm currently using WD7.
The Wifi problem happened when I was using stock ios 4.2.1 as well, so it must be a hardware issue.

Yes, I would think so, unless you do not have a baseband version.  Also, you did make sure to set up as a new device when restoring to whited00r right?  Otherwise, it could have been a odd backup related bug when you restored to whited00r that the issue transferred over.  I highly doubt that though :(

Of course I set it as a new iPhone.
Changing a hardware for iPhone 3g is a waste of money as there is many devices cost as much as the money, so I think I'd better get a new phone in the future then.

Well then, it seems you are out of luck and have some broken hardware on the phone :( 

Yes, replacing the hardware is not worth it, especially in this case as it is the motherboard that would need to be swapped out (pretty sure, unless it is just an antenna... Greyed out is normally chip failure).
