Follow all of the troubleshooting steps. You can even try restoring the device as new: iOS: How to back up your data and set up your device as a new device
If the wi-fi remains greyed out, your device needs service.
If within warranty, it should be free.
If not, it will probably cost $199 USD + tax.

Unable to connect wifi via netctl - Unregistered Authentication Agent

I have a previous post int the Newbie Corner that went unanswered, so I figured I'd try again here now that I have some new information. The post is here...
https://bbs.archlinux.org/viewtopic.php?id=197031
And here's a copy of that post so you don't have to open it in a new tab.
ORIGINAL POST:
I have continually been having issues with netctl failing to start an automatic profile for awhile now, but I have been able to manually bring up my connection once my system is up and running. Today I am running into the issue where netctl will outright fail to connect during a manual attempt. When viewing journalctl -xe the error I receive is:
WPA association/authentication failed for interface 'wlan0'
Failed to bring the network up for profile
I noticed that there is a 'fix' for this issue on the Arch Wiki which simply states to bring wlan0 down with ip link, then to start the profile with netctl again. I went ahead and gave that fix a try and got a new error.
Unregistered Authentication Agent for unix-process:1324:44567
The error goes on to provide a path to .../PolicyKit1/AuthenticationAgent,.
I have tried using NetworkManager as well, but I'd prefer not to use it as I seem to have more problems with it over netctl, and that is why I currently have it disabled. Any advice on how to proceed would be appreciated. Also, I was connected to my home wifi last night without a problem, and I have tested the wifi connection with my phone, which authenticates and connects without a problem.
EDIT:
I did a bit more digging and found some startup errors issues via dmesg with wlan0.
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
wlan0: authenticate with 00:24:b2:71:b8:27
wlan0: direct probe to 00:24:b2:71:b8:27 (try 1/3)
wlan0: direct probe to 00:24:b2:71:b8:27 (try 2/3)
wlan0: direct probe to 00:24:b2:71:b8:27 (try 3/3)
wlan0: authentication with 00:24:b2:71:b8:27 timed out
The last 5 lines of this error repeats about 7 times before stopping. I use a broadcom card and my 43xx driver loads without a problem, I've been using it for awhile now on various distros.
b43-phy0: Broadcom 4311 WLAN found (core revision 10)
EDIT:
Well after doing some research, I found this existing bug.
https://bugs.archlinux.org/task/44821
Involving wifi not working under kernel 4.0.1. I noticed a Broadcom card listed by one of the users who was having the same problem, so at this point I'm probably going to wait until I get home to test my laptop on my home wifi again, then if I run into problems I'll downgrade my kernel and see how things go.
NEW POST:
So after all of that I tried my laptop at home again, and netctl-auto connected flawlessly to my wifi at home, which has led me to believe that the problem has to do with the message...
polkitd[1087]: Unregistered Authentication Agent for unix-process:2582:96758
I had previously noted that I would downgrade my kernel, but at this point I'd hate to do that considering netctl-auto is working.
I have also tried connecting via wifi-menu, and when I try that I get the message
Interface 'wlan0' is controlled by netctl-auto
After which authentication fails. I have stopped netctl-auto via systemctl using systemctl stop [email protected] and tried again. I end up receiving the message error message from systemctl that the job failed, and viewing journalctl -xe shows the recurring Unregistered Authentication Agent from polkitd.
Any help would be appreciated.
EDIT:
The issue continues. I have enabled the netctl profile I am currently working in netctl-auto with netctl enable profile, and that has not allowed the profile to automatically start up as it would with my home wireless connection. Something I have been noticing is that upon boot, without attempting to connect with netctl, is that wlan0 is not up.
IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
I have manually brought it up and immediately receive a failed message from systemd regarding my profile in netctl. If I do not manually bring it up with ip link set dev wlan0 up, then when I try to connect with netctl start profile, netctl will not bring wlan0 up and it will leave it in it's previous state.
The odd thing is, even with wlan0 in a down state, systemd is giving me the error message...
WPA association/authentication failed for interface 'wlan0'
Which is odd because netctl shouldn't be able to pass authentication is wlan0 is still down.
I've been at this for 2 days now and am no closer to fixing this than I was yesterday. I could really use some assistance. At this point I believe I may just downgrade my kernel and hope this fixes the issue, if not then I'm silently hoping my laptop won't connect to my home wifi when I get home so I can diagnose this problem via ethernet.
EDIT:
Well here's something new. When viewing why netctl-auto fails on startup via systemctl status [email protected] I am getting the reason of
Could not create the configuration file for interface wlan0
At least now I have a bit more to work with.

I am unable to connect wifi on my phone 4s since last 2 weeks... I am living in shanghai and did not have this issue since 2 weeks... iPad works fine... Please suggest some measures... Tried the on off reset settings etc. but no luck ...
In fact after updating the software to the latest version I am having more of this... Sometimes the wifi button freezes an I can't even slide it to on / off...
Thanks

Noooo! Actually I too had d same prob wit my iPhone 4S. When I connect to my wifi network it won't get connected or it wil be grey scaled! I took it to d istore and since I had warranty they replaced my IPhone. It iPad charger has high volt than ur iPhone charger so when u connect wit it, there is a chance where large amount of current passes thru ur iPhone. So for sure it wil damage ur motherboard and its parts! Many said that iOS 6 or 6.0.1 or 6.1 was d reason for tis wifi prob! But apple never made its mistake wit it's software. If and only if u hav hardware prob u wil hav these sort of wifi prob Bluetooth prob! So best way s to replace ur iPhone!

Well, it seems the problem I listed in my previous post (unable to wireless sync with iTunes 10.2) has resolved itself. My iPhone now syncs wirelessly. Happy for small miracles!

I have an iPod touch 4th gen and it updated by itself to iOS6 without a wifi connection. When I unlocked it, it told me to connect to iTunes. So, I updated the software and when the update was finished, my wifi button was greyed out. I'm cant turn on wifi

My iPod updated by itself without a wifi connection. It told me to connect it to iTunes so I did and I updated the software and everything. After it was updated, my wifi button was greyed out and I don't know why. I sent it in to get fixed and the Apple store did NOTHING. I still have about 48 days left on my one year waranty and I don't know what to do to fix the problem. Please, does anyone know how to fix this issue without selling it or replacing it? I've tried all the troubleshooting techniques and nothing is working. Someone help.

Hi, my wifi button just greyed out a few minutes ago and I can't connect to wifi. Have followed instructions given by Apple support but it's still not working. Does anyone have a solution? Thanks

Hi, my wifi button just greyed out a few minutes ago and I can't connect to wifi. Have followed instructions given by Apple support but it's still not working. Does anyone have a solution? Thanks & Happy New Year :-)

First, you don't have a 5+ year old 3GS. The 3GS has only been around for under 4 years. In fact, 5 years ago there were NO iPhones; the original iPhone (2 generations before the 3GS) came out on June 29, 2007 - not quite 5 years ago. The 3GS was released June 19, 2009.
That aside, you can sync multiple phones to one computer - see http://support.apple.com/kb/HT1495. boogeyman is wrong. It is 100% safe to create an additional user name on her computer, log in with that name, and back up the phone. See this for details on what you want to do: http://support.apple.com/kb/HT2109

Hi Holliecollie93,
It sounds very frustrating that you are unable to use wifi with your iPhone. I do have an article that I would like you to use in order to troubleshoot this, though it sounds as if you have already done some of the steps provided -

Specifically -
Resolution
Follow these steps to resolve the issue:
Restart your iOS device.
Make sure that airplane mode is off by tapping Settings > Airplane Mode.
Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
Make sure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
If you still can't turn Wi-Fi on, please contact Apple for support and service options.
Thanks for using Apple Support Communities.

Wifi option is greyed out in my phone. Please help me to fix this

Start by working through http://support.apple.com/kb/TS1559 and if that doesn't resolve it, some have found it helps to go to Settings and set Airplane Mode ON and Do Not Disturb ON. Power down and wait 5-10 minutes and power up. Got to Settings and set Airplane Mode OFF and Do Not Disturb OFF

TS1398 the wifi bar is greyed out what does that mean?

The wifi bar is greyed out what does that mean?

If that doesn't work:
1. Backup to iTunes (NOT iCloud)—be sure to backup Apps
2. Delete all content
3. Set up as new—don't restore from backup
4. Restore from iTUNES (NOT icloud) backup
5. Then re-add your content.
