This is an indication that your wifi chip is malfunctioning. If a software restore (as a new phone, not from backup) does not fix it, it is definitely a hardware issue. If you're still under warranty and can get to an Apple store, then set up an appointment for a genius bar and they will replace it no questions asked.

If it's not under warranty, but you feel comfortable opening it up (if it's a second or third generation iPhone) then do so and reseat all of the cables. Sometimes this can be enough to set everything back in working order. After all, the iPhone is nothing more than a very very VERY miniaturized computer, and computers can exhibit odd behavior as well when their cables and sockets aren't tightly seated.

If you feel so inclined to try and dig in and fix it yourself, iFixit has many detailed guides on disassembling the iPhones -- http://www.ifixit.com/Guide/search/iPhone -- but you may be out of luck if the chip itself is broken. That'd require replacing the logic board in most cases.

Yeah my iPhone 3GS has done exactly the same! It says "No Wifi" 'grayed' out. I dropped it in water but everything is okaay after i dried it out but after a while it was all totally fine but then i couldn't get wifi at all?
What can i do except get another because it isn't under insurance for water damage so i can't get a new one jus because the wifi isn't workin because they will see that the sticker is red in the headphones port! But it jus won't let me connect to it + will charge off my laptop but won't display my pictures on it on "my computer" like it should do. Any help guys pleaase because i really need the internet on it <3

The phone is most likely corroding from the inside, slowly taking out each component one by one. Only way to get it fix is to have it replaced and id suggest taking it down to a Apple Store to see how much it would cost for a replacement unit. :)

I have had the same problem on my iPhone 4 MC model with baseband 4.11.10 on 4.3.3 firmware.

unlocked using gevey sim

WHAT I NOTICED WAS THAT WHEN I HAVE NO WIFI MY IMEI ALSO IS LOST as in comes up blank

i have figured a way to fix this by resetting all settings..
This solution works most time but some times i have to do it couple of times and also put phone on airplane mode to get it going again

my prob now is that its quiet irritating having to reset the phone more than couple of times in a day..
I hope someone can advice on a proper fix for this problem


is this a hardware issue or a software one?

DO NOT try this. You could do more harm than good. Any plastic could soften and I don't think even AppleCare + would cover this as this would considered abuse. On top of this is this persons first post and has no credibility. I hope the admin delete his post as I believe it is meant to do harm.
