Q: iOS 6.0.1 WiFi Still Greyed Out

I asked about the phone I was given at the service shop and they said it was a factory refurb from Apple. It is as new, but can consist of more or less used components. In my case (in Sweden) the warranty is the original warranty in case you have more than three month left, otherwise it's extended so you get three months warranty on the replacement phone.

Looks like brand new, works like brand new.

Got another 90 days warranty.

Fine for me!

I have been following my thread and have found some things. I am currently on holiday and my cellular data coverage is terrible, so I need wifi to do any type of data related function.

I found that the Wifi works after you Reset Network Settings in General and will continue to work until you lock the device. I don't know if auto lock or manual lock affects the bug.

Sometimes after Reset Network Settings the wifi is completely grey so I do it again and it works.

Since Apple will replace what was my NEW iPhone with a refurbished model, I will continue to wait on the replacement. My warranty expires in late January, and I truly believe that this is a software based glitch doomed to return even on a replacement device. I am hoping either a 6.1 or 6.0.2 update will fix this for me.

Good luck and good hunting. I have not had to do the freezer trick since I have been on holiday but I do have to Reser Network Settings about three or four times a day. 

So, ios6.0.1 works fine on my iphone 3gs that has been dropped and chucked around more often than not, can pick up wi-fi perfectly.  But my brand spanking new iPhone 5, cannot get a wi-fi signal to save its life!

Seriously frustrating as it took an age to get the update down.

I have an iPhone 4S and was experiencing the same wifi grey out and blue tooth issue. I tried everything in all the posts I could find. No luck until I rang apple care Australia and the tech guy there fixed over the phone. I just went to settings, general, reset, reset all settings. All works fine now. Hope this helps those who still don't have wifi.

This one works!! Thank you so much!! How come the Apple Care here in the Philippines did not come up with that temporary fix? Again, thank you!!

I'm glad it worked for you. It's working permanently for my iPhone. Big thank you to Brian at apple car Australia for that fix. He worked it out on his personal iPhone at his home in his spare time. Legend. All it did to my phone is wiped wallpaper, but I put it back on and it kept all my apps etc where they were and now my iPhone is working perfectly.

Simple fix. A lot of other apple techies told me it was hardware fault when it wasn't.

this didnt work for me, i also tried reseting my phone completely with a new installationg of the iOS instead of restoring it and gives me same results, wifi still greyed out. i wont have my phone replaced with a refurbished one, knowing it will come with the same problem. Probably switching to Android soon... ='\

"i wont have my phone replaced with a refurbished one, knowing it will come with the same problem."

Why would you make that assumption? My replacement phone works nicely, no greyed out Wi-Fi button anymore.

My experience tells me this is a two part problem though, it's both hardware and software. Replacing my phone solved the greyed out button problem, replacing my Wi-Fi router solved the connection problem. You may have to do one or both of these.

Im not assuming anything, replacing the phone in many cases did not fix the issue, i've been looking in many forums such as this one following this issue =\ nothing left to do but wait for a new update i suppose. Yes, i did replace my router as well.

If you've done the restore as new, restore all settings and reset network settings then it is a hardware fault, waiting for an update and replacing your existing resources are a waste of time and money. I called up apple on monday, sent my 7 month old scratched up iphone back and got a 1 month old replacement on friday. They put a whole new housing and battery over it so I cant even tell if it's new or not.

On another note I checked my serial number and it says a production week of 37, and it came with OS5, do you think its new or reurbished? (4s 64gb)

I dont mind either way, a one month old tested and working phone with a new battery is an upgrade from a 7 month old one.

So I had this issue with my 10 month old iPhone 4S

Went to local Apple shop and made my case

Ended up with a warranted refurb iPhone 4S with an extended warranty all free of charge

I'm experiencing the same problem! I got wifi problems since 6.0.1, everything worked fine 10 months before!

Is there any solution yet? I tried everything! Is the problem hardware of software related? It seems software because everything worked before 6.0.1?!

The nearest Genius-bar is a 400 miles roundtrip and I have only 1 month warranty left...

What should I do? I don't want a refurbished one...I just want mine to be fixed...

it's a hardware fault, you have no option but to get a refurbished one.. unless you dont want wifi.

Thank you for your reply Lukedlang.

Is there any explanation how this hardware fault comes up right after the update? Before my hardware worked fine for 10 months... My hardware works half of the day...but fails the other half...
