4.2.1 iPhone 3g wi-fi greyed out

HELP!!
My iPhone was on wi-fi this am, and now the wi-fi is greyed out as not even an opyion. I did al of the resetting and still nothing. It is @ 3.5 years old - and suggestions besides sending it away or using a heat gun?

I had the same problem with my old iPhone 3GS. After I upgraded it to IOS4, it lost its WIFI ... At the top of the screen there were no bars, just an E. And the settings screen just said NO WIFI in grey letters. I tried everything I could, but couldn't fix it. So, I went to the Apple store. After trying unseccessfully to restore it for about 45 minutes, they GAVE ME A NEW iPHONE!!! God bless Apple!
Get yourself to an Apple store!

I Have had my iPhone 5s since feb and never had an issue, but just yesterday the finger print scanner stopped working... Went back in to enable and the options are greyed out.. When I click them to enable them it just says failed. Have restored and turned off loads!! Help!!!!

Try a reset, hold down the home/sleep button together until you see the apple logo and then release then wait for the phone to boot back up.

You still have a 4 digit passcode turn on right?

New iPhone 5 iCloud setting greyed out

In settings on my new iPhone 5 the iCloud option is greyed out. How do I make it available?

Thanks very much, that's great!
I wonder why the Restrictions on my old iPhone 4 don't prevent access to iCloud. Mysterious.

New iphone - restore paused, itunes greyed out

Ok, so my old iphone 5 died today - i backed everything up on to my icloud when plugged in to computer.
went straight to store, got a new phone
stayed in store until apps started downloading, genius said i could leave as everything seemed to be downloading fine.
got home, and they looked like they had paused, Initially I thought it was just because I had lost connection... So i restored everything again and the same thing has happened.
Most of my apps have paused downloading, and most of my itunes songs are greyed out???!!!!
So, I have done the whole on off, hard reset... and settings thing...
log out and back in via 'itunes & App stores' my ID is correct email
BUT when i go to try the same in 'icloud settings' it brings up my old Apple ID email address, and the fields to change your email are blanked out so the old email wont budge!!!!!!?????
everywhere else my details are my new email address - work fine to download etc.
I have contacted apple support chat people, they took my through support online - outcome 'book a phone call' only slot they have in at 2.15AM!!!!! in 10 days time??!!!!!! I had to drive over an hour to store today, and i wont be doing that again!
Please help! I will be sooooooo grateful!!!

Thanks very much, that's great!

Iphone 4s wifi stuck / greyed out at ios 6.1.3

Hey, I just upgraded to ios 6.1.3 and my iphone wifi button greyed out also my processor started hanging a lot so i tried number of methods like software restore, freezer but nothing happened instead i also upgraded to ios 7 and i tried freezer method again which ruined my iphone's audio, now its audio is very less
Can anyone please help.....?

What a a lot of people have been telling me is to turn Airplane Mode on and then reset settings and iPhone, and that should sort it.
I haven't done it myself, But you could give that a go
As for the audio, sorry I don't know about that.
Hope you sort it out soon, my wifi is having trouble also (silly phone)

Apple aware of ios7 iphone 4s wi-fi greyed out due to burn out?

Hi!
Correct me if I'm wrong. I read people having issues with their iPhone 4s because they have updated to
iOS 7 which sends to strong signals to the Wi-Fi chip and burns it. Because of that the Wi-Fi option is greyed out.
I could be wrong but is Apple aware of this? I am still running iOS 5 and don't want to upgrade because this is one of the reasons.
Do you have the same problem?

It seems many people have the same problem with Wi-Fi greyed out. This is a serious issue. Here are threads with probably the same issue if I'm not wrong.

Yes, and it goes further back than iOS 7: https://discussions.apple.com/thread/4909703
It's not the iOS. It's the hardware. It's defective. Get it serviced, as already described in other threads.
Contact Apple at getsupport.apple.com or schedule an appointment at a local Apple Store at http://concierge.apple.com/reservation/us/en/techsupport/.
If you are within warranty, you might get a free replacement.
If not, then expect to pay $199 USD + tax for an out-of-warranty replacement.

TS3988 I can't access my iCloud preferences in settings on my iPhone. It stays greyed out

I can't access my iCloud preferences in settings. The icon stays greyed out and I simply can't tap on it, any ideas what I am doing wrong?

Go to Restrictions and turn that off. When on, you are not able to get into most settings.

IPhone 5 wifi symbol greyed out/wifi will not stay connect?

I had an iphone 5 that was having some battery issues, so I took it in and they replaced it with a new 5 (16 gig). I restored my backup, and when the restore was done, I couldn't turn on the wifi. The pull up setting was blacked out and in settings I couldn't move the switch to 'on'. I rebooted the phone, and that fixed the problem for a little bit. Eventually my wifi connection would either disconnect and quickly reconnect or just turn off all together. This can't be a wifi issue, since my ipad and my families apple devices are working fine. I've tried deleting my phone and using it as a new one, reseting the network settings (multiple times) and almost everything I can think of. This has been going on for a few weeks, and every time the wifi cuts out I have to either reboot the phone multiple times, or, if I get lucky, just turn it off and then on again. Its getting annoying and I don't know how to fix it without switching to a new, non apple device, which I really don't want to do. Any advice? (i have the newest software btw, updating changed nothing)

Hello emconway,
Check against the article below with the troubleshooting that you have done. You also said that you had your iPhone replaced and it still has at least a 90 day warranty on it if it was serviced by Apple, so you may need to take it back to have it looked it.

IPhone 4S wifi greyed out on iOS 7 - Apple's in-store response

I was in the Apple Store on London two days ago to complain about my new IPhone 5s having wifi outages and a battery life of about 5 hours (of standby) when a woman came in and asked why her iPhone 4S has a greyed out wifi icon since the upgrade to iOS7. She was told her hardware had failed and that she should buy a new phone, or spend hundreds of pounds having it repaired by Apple. If only I was aware then as I am now that Apple are destroying iPhone 4 phones with their new software;
http://www.nextiphonenews.com/2013/11/why-is-apple-inc-aapls-ios-7-update-destro ying-old-iphones/
I presume this is Apple's company policy to sell more units. Sadly I didn't intervene but I wish I knew now that it's a common problem and that Apple are deleting posts on here about it to cover up. This elderly woman's phone was 18months old, so even out of warranty it's with the scope of consumer law for a free replacement.
I hope posting this helps others out there who might be being told similar things.
...my 5s? Refund for me. It doesn't work at all. Worse than the iPhone 4 it replaces in every way.

Is there a technical support question in that conspiracy theory somewhere?

If you are still unable to turn Wi-Fi on, please contact Apple for support and service options.
Waiting for Apple to release the next update won't do any good.

HT6154 My iPhone 4g wi fi is greyed out. I've backed it up to my computer after having a lengthy discussion with an Apple tech person at the apple store. What should I do next?

My iPhone 4g cannot connect to wi fi. It is greyed out. I've spent the day at Apple, backing up my iPhone to my computer, resetting network, and rebooting everything many times. What is the next best step? The Apple tech at the store said that my phone no longer has a warranty and I should either get another 4G or go to a 5c. I've seen that iPhones generally have a greyed out problem and that it's not software, but a hardware issue. Help!

After taking my late 2009 15 inch macbook pro to the apple store, the genius completely erased my computer and reinstalled the Mac OS X software, but the problem still persists.
I also took it to my college tech support center, they tried to take the ram out and reinsert it and clean up the dust, but the problem still remains.
I am able to use my computer in Safeboot mode (only)
Well it could still be a software problem if you installed a third party program after the OS X wipe and install, because by booting into Safe Mode it disables certain functions of OS X and hardware. Check for updates or problems for all your third party software, include everything, including menulets, System Preference panes, hacks and so forth.
If you restored any sort of software from backup like TimeMachine, it likely was corrupted data and now is returned.
If the college tech support found a lot of dust clogging the rear exhaust vents behind the fans, then likely the heat damage done to the machine has already occured and can't be reversed. Video cards are usually first to go, which Safe Mode does disable the video card somewhat.
Run through this list of fixes, it's systematic in nature, also has a Hardware Test to see what's going on
..Step by Step to fix your Mac
Too bad this is occurring to a mere 4 year old machine, but dust will do that. Here is the culprit that Apple doesn't tell anyone about.

ITunes 'sync' for iPhone 6 now 'greyed' out?

Yesterday and today the Sync at the lower right corner of the iTunes Mark's iPhone Summary screen is greyed out. I've never run into this before. I've disconnected the phone, rebooted the phone, open and closed iTunes. As a further test I checked iTunes to write over the iphone's Contacts, Appointments and Notes.The lower right changed to Apply/Revert, I clicked Apply, The top sync info screen flashed a couple of times but did not go through the sync process.
Any suggestions?
Mark

Since I couldn't find an edit option to my initial post, here's a few more observations:
The box 'automatically sync with iPhone when connected' is checked.
I rebooted the computer with the two USB port connectors unplugged (iPod and iPhone) then reconnected them after the computer finished loading windows.
I checked 'sync with this iPhone over WiFi' and unplugged the phone. Apply/Revert appeared, I hit Apply. The top sync screen said 'starting to update files, the progress bar appeared for about 1/8" (~10 seconds) then disappeared. I unchecked sync with WiFi.
