You know you have this problem when the Wifi button is grayed out or you repeatedly receive the “Unable to Connect” message over and over again, particular after you’ve upgraded your iPhone 4S to iOS 7. Good ole updates causing you nothing, but headaches, but fear not! Here are a few solutions to Fix iPhone 4S Wifi Problems After iOS 7 Update.

Fix iPhone 4S Wifi Problems After iOS 7 Update

1. Restart Network Settings

Keep in mind – doing this will reset all recorded data like Bluetooth pairing records, Wifi passwords, VPN as well as APN settings.
Touch ‘Settings’.
Select ‘General’.
Scroll down to ‘Reset’ and select it.
Tap ‘Reset Network Settings’.
You may also have to restart your iPhone.

2. Reset All Settings

All of your preferences will be removed, but you may be able to solve the Wifi problem. Here’s how to do it:
Touch ‘Settings’.
Select ‘General’.
Scroll down to ‘Reset’ and select it.
Tap ‘Reset All Settings’.

3. Upgrade Your Software

You may have already upgraded to iOS 7, but there may be a new update available to you. You can do this in iTunes or by going to Settings -> General.

4. Put Your iPhone 4S in the Freezer or Fridge

No joking here. This has actually worked for some and here’s why: the Wifi chip produces heat and many suspect the iOS 7 upgrade causes the Wifi chip to overheat, thus knocking out its effectiveness. By placing your device in the freezer or fridge for a few minutes this cools down the Wifi radio chip temporarily solving your Wifi issues when you take it out of the cold. NOTE: Putting your iPhone 4S in the freezer or fridge may cause potential damage to your device.

5. Downgrade Your Software

As many suspect – the reason why your Wifi is spotty or grayed out on your iPhone 4S is due to the iOS 7 upgrade. By downgrading your software – or not doing the upgrade in the first place – your Wifi receiving abilities should be fine.


If you’re still experiencing this issue a trip to the Apple Store may be in the cards. A Genius or two should be able to diagnose the root cause if the above tips don’t work for you when it comes to your iPhone 4S Wifi Problems After iOS 7 Update.
