Unable to turn on Wifi on iPhone 4S iOS 7.0.3

Hey ab_VaD3R,

I found the following recommended steps for when the setting to turn on Wi-Fi on your iPhone appears "grayed out" or dim:

Follow these steps to resolve the issue:

1. Verify that airplane mode is off by tapping Settings > Airplane Mode.
2. Reset the network settings by tapping Settings > General > Reset > Reset Network Settings.
   Note: This will reset all network settings, including Bluetooth pairing records, Wi-Fi passwords, VPN, and APN settings.
3. Ensure that your device is using the latest software. To do so, connect your device to your computer and check for updates in iTunes.
4. If your issue is still unresolved, perform a software restore in iTunes.

I work in a shop that sells apple products and iphones and have had 12 - 15 costumers come in with the same problem. "I am one of them"

The problem is the new update 7.0.3

unfortunatly there is no fix for this problem until apple bring out a new update because the problem is in the coding for the 7.0.3 version and there is NO WAY TO DOWNGRADE to a older version.

so we will all have to wait !!!!! 😟

I have the same problem..it just totaly same..oh god im really2 regret update my Os.. huh..there is no other solution to overcome this problem?please somebody help us..

I have just spoke to apple customer support and they informed me it was a hardware problem which only occured after a software update. thanks for this info but still without wifi

Same problem here. Any solutions yet? Did Apple provide any assistance?

With ios 7 update on iphone 4s wifi goes grey is it hardware problem or apple fix with new update. Suggest me please.

Just adding to the list of customers having this problem. Have never had so many second thoughts about Apple brand loyalty since Mavericks and iOS 7. Maybe I'm just getting old.

none of that stuff works. delgadoh

Guys - there is no fix to this problem. Just got out of an Apple store genius bar appointment. iOS 7 kills the wifi/blutooth chip. hardware failure. If you're out of warranty or don't have apple care or can't upgrade your phone you are out of luck. They know it's a 4S problem only. You upgrade to iOS7 at own risk. Pretty big failure for apple.... IMHO

After a lot of intermittent flaky behavior (choppy settings, no networks found, settings disabled, etc.) eventually the antenna failed completely and the settings greyed out. Fortunately replaced under warranty. The Apple Genius claimed not to be aware of issues with the 4S and also suggested updating to 7.0.3 but I can certainly say that the problems happened after 7.0.3. (on a 4S that was only a week old and replaced because of other issues.) Two replacements in a month.... something in 7.0.3 makes the wifi antenna run hot and fail until it fries out.... so will remain on 7.0.2.

same problem here it occured several days ago after installing 7.0.3 by about one week. wrote to apple store but got no reply. how can we tell when we will be able to fix the problem? absolutely no functionality in terms of wifi, mail, chat, viber, maps, weather, etc...
