IPHONE 4S CANNOT ACCESS WIFI

Cannot connect to wifi grayed

My iphone 4s is also completely useless when it comes to connecting to wifi. It won't even detect connection spots.   I do not know what happened but other people with other apple products do not seem to have a problem.
Depending on location it occasionally catches it, however it has been down for WEEKS now.   I purchased my phone from the apple store in January.   It should not be acting like this regularly.
I tried resetting the network settings.   Nothing works.
I am afraid to reset it to factor settings because I feel this is an internal problem with the phone, not the software itself.
I am not in North America right now, so the only thing I can do is be inconvenienced and wait. Unless there are other suggestions?

IPhone 4 cannot access wifi from airport

Both my girlfriend and I have iPhone 4's. We cannot access wifi from my personal home airport. When we go to log into wifi and we type in the password, we receive a prompt saying, "Incorrect password for....". I am writing this on my MacBook, logged into my wifi, with the same exact password???????
I've tried everything. Resetting iPhone, MacBook, and Airport. I also tried resetting my password and resetting the network settings. I don't know what else I could possibly do. It's frustrating because my girlfriend is on a data plan and can't utilize our wifi.
Any ideas???????

My iPhone frequently cannot access wifi

Recently my iPhone 4S has become quite random when it's accessing the net via wifi. About 80% of the time it thinks there is no network and 20% it's fine. I access the same wifi networks that I have been using before. When this happens I can get access to mails etc by disabling the wifi and connecting via 3G. However this in not a very practical solution. Has anybody got any ideas? I have re-set the phone but the prolem persists.

The basics from the manual are reset, restart, and restore.
Have you tried any of these?

IPhone 3GS cannot access to 3G network after upgrading to OS 5

My iPhone 3GS cannot access the 3G network after upgrading to OS5. I have checked with my operator and shows that their 3G network is working fine. Only cannot access through the phone. When I enable 3G, there will be no service for my phone. Wifi is working fine.
Any idea how to resolve this?

Thanks, I will try this method. After restore and syn, will it automatically upgrade back to OS5?
No. If you have 5.0.1, then you will get 5.0.1 back. Restoring should still fix it though. I would prefer to have you back up to iCloud, because there are many known issues/errors when trying to restore via iTunes on iOS 5 or later.

Cannot access wifi since upgrading to ios5.1

I upgraded to IOS5.1 this morning. iphone 4S was fine, but ipad wifi did not reappear on completing the upgrade and when I enter my password, it says cannot access network. None of the details of the network are listed except for the DNS and I can't manually enter them. Anyone have any ideas or similar problems?

I'm seeing the same problem. Running iOS 5.0.1 both my original iPad and my iPad 2 were rock-solid on my WiFi network. Since upgrading to 5.1 neither device is able to connect for more than a few minutes. Device connects on a reboot or when resetting the WiFi settings but after a minute or two the network just disappears and the iPad says it's unable to connect. My iPhone 4 and 4S both work fine on the network with 5.1. This issue appears restricted to iPads.
Is Apple aware of this issue?

Microwaved iPhone 4, cannot detect WiFi.

I have microwaved my iPhone 4 for 3 seconds (hearing rumors about it charging your phone) and it turns out now it cannot detect WiFi what's so ever.

Seriously? You bought into that crap?
Guess you'll be buying a new phone.
Don't believe everything on the Internet...

Iphone 5 cannot locate wifi after restore

I just tried to restore my new iPhoe 5 from the backup of my old phone and now the nes iPhone 5 cannot locate my wifi system even though it was locating it fine just before I did the restore.

Once after a restore I noticed WiFi was off. So please excuse the obvious nature of these questions, but maybe they will help:
Is Settings > WiFi set to "On"?
Is Settings > Airplane Mode set to "Off"?

My iPhone 4S cannot access my purchased apps in my App Store.

I cannot access my previously purchased apps on my new iPhone 4S after the last update. It sure is annoying since I just got this and now I can't even get my apps from my old phone on here. Anyone know what to do??

Just by reading this forum i can tell you that myself among others are having the same exact problem. It must be an apple issue

Cannot access wifi or Bluetooth on my I phone

Cannot access wi-fi or Bluetooth wi-fi button grey out same as Bluetooth .

Is there any hope for an iPhone 4s that cannot access WiFi after iOS 8.1 ?

I bought a "very good" used unlocked 4s on eBay back on Oct 2 ... it arrived with iOS 8 installed ... AT&T folks told me not to load that SW when I went in to move my SIM from an Android phone to the iPhone ... when the saw it was already loaded they were amazed that it would even start up ... but it seemed fine until I got home and tried to set-up my WiFi ... all kinds of problems ... which led to upgrade to 8.01 and then to 8.02 ... all the while hoping to see some fixes ... but things went from not so good to terribly bad ... Bluetooth was off .. and the option to start it was greyed out ( but the little rotating gear continues to run constantly - can't stop that ) ... similarly the WiFi option was off and and was likewise greyed out and inaccessible ... then messaging was no longer accessible ... and to top it all off the phone now discharges in 2-3 hours ... even when powered off ... kind of scary ... but on Mon the 20th I was able to download iOS 8.1 to my Windows XP iTunes (took almost 6 GB to do that - downloads a huge file and then has to extract it, before installing it -- and instead of getting rid of the mess it makes, it puts the no longer needed files in the recycle bin taking up more space -- took me 6 hours to get thru all of that .... and all for naught ... still nothing works ... tried resetting networking ... resetting everything ... useless ... even drove 10 miles to a Starbucks to get a different WiFi ... but nothing works.

You should try these steps:
iOS: Wi-Fi settings grayed out or dim
Symptoms
In rare instances, the setting to turn on Wi-Fi on your iPhone, iPad, or iPod touch may appear grayed out or dim. You might see the following when you tap Settings > Wi-Fi.
If this occurs, your device won't respond when you try to turn Wi-Fi on. If you're using iOS 7.1, "Wi-Fi Not Available" might appear in Control Center.
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. If you can turn Wi-Fi on but are experiencing other issues with Wi-Fi, see how to resolve those Wi-Fi issues.
