I have an Iphone 4s using IOS 6. My WiFi button is switched off and grayed out and not working. After searching the forums for answers I eventually called the tech support from Carphone Warehouse here in Ireland and they told me its a hardware/NOT SOFTWARE issue due a faulty antenna and have to have it sent to Apple for repair.
Hve been waiting for a call from Apple support but no joy as of yet.
Out of the blue, my iPhone 4 with AT&T 5G hotspot stopped working via USB, bluetooth, and wifi. After researching fixes, resetting network, resetting cellular data, everything- I turned the phone on airplane mode for 30 seconds, turned if off airplane mode, and hotspot connected as normal right away via wifi.
If you have tried everything, give airplane mode a shot.

I don't think that is necessary. There are loads of fixes in this thread and the only one that worked for me is resetting the network. Go to Settings>wifi>blue arrow next to your network, scroll down to reset network and reset network. I see this has worked for a few people and it did for me. Best of luck.

I tried every "fix" on this forum and every other forum regarding this issue. None of them worked for me. The issue is millions of people own Apple products with IOS6. Thousands of people are having wi-fi issues. There are not enough people with the issue for it to make a difference with Apple. I was a lucky one. My issue began with a new 4S. After 2 phone support calls and a trip to the genius bar (all telling me that they were not aware of any issues with wi-fi), Verizon swapped out my phone. The new 4S had the same issue. Verizon saying it was an Apple issue, Apple saying it must a Verizon issue. I even went through the expense of a new router, even though every other electronic device worked on my password protected wi-fi. I will also add that my husband has a 4 upgraded to IOS 6, and my son has a 5 which obviously came out of the box with IOS 6. No issues with wi-fi. On day 8 I decided that I could not spend hours every day working on this. I demanded another phone from Verizon. I switched to a droid. Not one connectivity issue.
There are such a small percentage of people having this wi-fi issue that it is not worth the time or money for Apple to fix it. The customers who have the Ipad 2 and 3 along with the Iphone 4S (the devices that apparently are the most prone to this IOS 6 issue are left to fend for themselves. I am extremely dissappointed because I am an Apple fan. Generally, anyone who bashes Apple is labeled an Apple hater. I am not. I truly am just a very dissappointed consumer who really wanted an Iphone and all I got was smartphone that wasn't very smart!
I hope for everyone's sake, I am wrong about not having the numbers for Apple to do something....
It's just hard for me to fathom that there seems to be no concern for this issue. I have spent days reading through all of these forums and trying everything that's been listed here. What people need to understand is that it is not an issue with our home Wi-Fi networks. Many people have several devices that all connect the same Wi-Fi network and work just fine. No matter where I go my phone does not find any available Wi-Fi networks it just says searching. If I continually reboot my phone I may get lucky and have it pick up my Wi-Fi signal. Or sometimes the Wi-Fi button is just greyed out and you can't even turn it on. I finally got it connected and I let it play Pandora for two hours straight and it stayed on Wi-Fi because the screen stays on while the phone is plugged in to charge. It seems to issue is with the phone going to sleep, once the phone goes to sleep the Wi-Fi disconnects when you Wake up the phone you normally see the Wi-Fi quickly reconnect but it's not doing that. My old android phone used to do this so what I did is I turn off the Wi-Fi sleep policy. But the iPhone does not have that option. My wife I will stay connected as long as the screen remains on. But when the phone goes to sleep for an extended period, for example overnight, when I wake up in the morning the Wi-Fi has disconnected again. Unfortunately many of Us who bought the iPhone 4S when it first came out are no longer covered under warranty so we're just stuck. I'm really disappointed because this has been an ongoing issue for so long for so many people.

It may seem like people don't care because there are actually many separate issues it seems. All the people that posted fixes of various kinds to WIFI issues, those fixes didn't work for me. My fix was to get a different wifi router than my netgear which is actually more of a workaround than a fix. But your issue sounds different than most of the others discussed.
I'm a bit surprised that more wifi fixes haven't come out yet, and that this all wasn't better tested before release. But just keep in mind that there are a lot of people with various issues, and we're all frustrated and we're all with you, it's just that what worked for one person may not work for you.
If wifi is more important to you than iOS 6, I'd downgrade your phone to iOS 5. No one likes to go back, but just weight your priorities.

I understand your frustration, especially when Apple wont let you purchase additional coverage unless done when you got your iPhone. I had the 'netgear' issue with IOS6 and iPhone 4S that worked fine elsewhere but couldnt connect to wifi. I switched to my previous Netgear router and also tried back leveling firmware which allowed joining the wifi but it wouldnt stay connected and often I couldnt get back on. All I can suggest, if you havent tried it, to change your security setup. I had been using WEP since day 1 of wireless at home and now all of a sudden I am told to switch to WPA for better security. Well I dont think security with WEP is risky but what I did do is to go to WPA2-AES with a 10 digit phrase/key and this fixed my problem. So if you have WEP try this. I found out using WPA2 is much easier than WEP - no more keying in a 13 hex character passphrase. Changing all the other devices on my network was easy with WPA2. Like you they all worked fine. I was also told by Apple, theres no going back to IOS5. I had the IOS6.01 update on. I went through a complete restore of my phone with Apple and quickly discovered things dont all go back to what they were when the restore is done. I wouldnt recommend that option. Forutnately for me I am not a huge DATA user so I managed to stay under 2GB until I went to WPA2.
Since I upgraded iPhone and iPad to IOS6, the biggest problem I am having is with Bluetooth. My headsets don't work with the iPhone and everytime I need to use my iPhone as a hotspot for my iPad, I have to reset the network settings on both devices. I also have occasional issues with texting from my iPad when connected to the wifi. Not sure what is going on, but I never had these problems before the upgrade.

Glad you finally got around to changing it as recommended and glad it solved it for you. I will tell you WEP is not a secure encryption. I know you keep saying/thinking it is but its a known fact that is is about as usless as having no encryption. You can google and read more info about it if you are still in doubt. Most anyone familiar with network security will tell you to avoid using WEP for wireless connectivity. Anyway glad you got all your stuff switched over as now you have a working iOS device AND a more secure wireless network.
<<<<<<<In fact, researchers in the computer science department of a German university recently demonstrated the capability to compromise a WEP-protected network very quickly. After spending less than a minute intercepting data (fewer than 100,000 packets in all) they were able to compromise a WEP key in just three seconds, and they did it using a system equipped with a mere 1.7 GHz Pentium M CPU, which is less powerful than the processor found in today's entry-level notebooks.>>>>>>
And thats a OLD article too.(2007) WPA2 is the current recommended.

It doesn't seem to have anything to do with that in my case and many others I have been reading. What people aren't understating is that no matter where I go, what type of router/AP is in use nor what type of encryption I use, my phone does not find ANY wifi hotspots. It just keeps spinning like it's searching. If I reboot or reset network settings enough times I might get lucky and it'll find all the nearby routers and connect to mine as it normally should. Anywho, Apple replaced my phone and it's working now. I did not upgrade to 6.0.1. It's odd the phone came with 6.0 installed. The description on my receipt says "customer lost wifi capabilities during iOS 6 upgrade". So it's a software problem. That and the fact that I didn't even have to finish explaining my issue before the Apple Store tech said they'd replace the phone confirms this for me. Hope this helps someone. Oh, and if you think your phone is out of warranty, try anyway. I went to the Apple website and it said my phone was OOW and wanted me to pay $20 for tech support. But I decided to go the Genius Bar anyway and it paid off. So I'm back on wifi and staying with iOS 6.0
Same issue.. wifi switch greyed out. Yesterdya took back and restored the phone and the process took an hour. After that wifi started to work but this morning gone again.. honestly this is such a shame. I notice people in different threads have been complaining for few months and no response from apple. My 4S ran out of warranty last month so I doubt if apple store will help.
This IOS6 has been nothing but bad news.
I will be switching to samsung for my next phone and tablet soon.
Posted this on another thread and will post here as well.
Just got a new iPad 4. Got it home from the store and it would not connect to my Netgear WGT624 v3 router. I knew there was nothing wrong with the router because my iPad 1 was connected just fine, as was my Android phone. Tried everything. Updated firmware on Netgear; tinkered with security settings on Netgear, changing TKIP security to AES (somebody suggested that on some forum) and then when that didn't work, dropping security altogether. Rebooting router; rebooting iPad. Disconnecting iPad 1 on the theory that maybe my router didn't like 2 iPads connected at one. Nothing worked -- it would not connect
Called Apple telephone support today. First person was clueless; got kicked up to more senior person. He tried to insist it must be my router (although my iPad 1 was connected just fine). He had me redownload IOS 6, which of course (as I could have predicted) did nothing.
So the new solution is that I take my iPad 4 back and they give me a new unit. I agreed to that, although I doubt it will solve the problem. From everything I have read, it is a software problem, not a hardware problem.
I briefly considered buying a new router, but decided I didn't want to go to the time and expense when there is no guarantee that will solve the problem, especially given there are widespread reports of router connection problems with IOS 6 . (And someone on this post mentioned they got a new router and it did not solve the problem)
Apple is beginning to remind me of Microsoft -- absolutely refusing to accept responsibility for their junky software. If I have the same problem with the replacement iPad 4, I will stick with my iPad 1. At the moment, I have a very expensive paperweight since an iPad that won't connect to the Internet through home WiFi is useless.
