Well two days ago I updated my IPhone 3G to OS 4.0.2 and now I wish I hadn't....
OS 4.0 was bad enough but after upgrading to 4.0.2 I have now completely lost the ability to connect to Wifi networks.

Basically the wifi option in settings is totally greyed out and it states "No Wifi".

I've tried hard reboot, double hard reboot, reseting network settings.

Wifi worked fine with OS 4.0 but has now gone grey under 4.0.2.

I've had a good look through the forums and can't find anything in relation to a fix.The OS 4.0 update has killed so many peoples wifi is there a fix available yet for this?
If not looks like tonight I will be trying to roll back to OS 3 if I can and fingers crossed this fixes it.

For those who are unaware to make the 3G phone run faster under OS 4.0 make sure you have no Safarai pages open when not using the internet and have turned off the spotlight search under things where its not needed.

Thanks
Steve

    Usually a greyed-out Wi-Fi indicates a hardware failure. You should bring your phone into the Apple Store for evaluation and replacement if needed.

    I have the same issue. Please post the results of talking to your provider (if that was really hardware failure)

    I also have the same issue.
    It happens when the phone was upgraded to 4.0.1
    I sent my 3G to provider and they said that it is a hardware problem. Anyway since my iphone it is not under warranty they do not replace the phone.
    Trying to fix the problem I restore the phone twice today. In both cases the wifi works perfectly only for a few moments and then it is lost permanently.
    As a result I think that it is not a hardware problem but probably the update 4.0.1 and 4.0.2 cause the issue. With those updates apple tries to fix the antenna problem in iphone 4 as I can remember

    I've experienced the same problem 12 hours ago. I updated my 3 months old iPhone 3GS from 3.1.3 to 4.0.2 and the wi-fi sign under settings turned grayed-out. I believe it can't be a hardware problem unless the update burnt my wifi chip, coz it was all working fine before the update.

    Xm... my 3G is also 3 months old. Please check if your bluetooth is still working. Mine is also dead. Wifi and bluetooth always searching for networks and devices without any result.
    I'm thinking the downgrade...

    Try this one http://bugreport.apple.com/
    I got an email from Apple Bug Reporter that ask me to attach my device log to the bug report. Device logs can be retrieved from the iPhone Configuration Utility.

    For the history, I restored twice the iphone today and the wifi is dead. Particularly after the second restore the sign in settings for the first time turns into grey: "No Wi-Fi"
