iOS 7 Bug Causes Wi-Fi Issues For Some iPhone 4S Users

Share:

It appears a widespread iOS 7 bug is affecting some iPhone 4S users. According to this Apple Support Communities thread (54 pages; 106K views), frustrated users are unable to use Wi-Fi on their iPhone 4S after upgrading to iOS 7.0.3, as the option is greyed out. Other iOS devices seem to be affected but primarily it is the iPhone 4S that is suffering the most.

iPhoneinCanada reader Trent shares his story:

Something about the iOS 7 upgrade / OS / bluetooth is causing the wifi chip in the 4s to die. Some are speculating heat issues where one can (temporarily) remedy it by putting the phone into the freezer. Others have not had success with it.

My wife’s 4s developed this problem after we tried connecting it to our new car via bluetooth and now the phone can’t use wifi and it approaching her data limit after 1 week. A visit to the Apple Store tonight resulted in them saying it’s a defective chip and there is nothing that can (or will) do.

The issue with no Wi-Fi means users with small data plans face going over their allotments and paying overages. Also, iCloud backups only automatically initiate when iOS devices are plugged in and connected to Wi-Fi. So, as you can see this is a problem for many people.

Some users have had mixed success with the following fix:

1. Turn off Airplane mode (if on)
2. Turn cellular data off
3. Reset Network Settings via General, Reset, Reset Network Settings

Anyone else out there suffering Wi-Fi issues with iOS 7.0.3?
