Thanks for the question. I understand the Wi-Fi connection on your iPhone 4S drops unexpectedly. That definitely sounds frustrating. The following article provides some troubleshooting steps that may help to resolve your issue:
Wi-Fi disconnects, or signal strength is less than expected
- Move closer to the Wi-Fi router (access point).
- Check for sources of potential interference.
- Remove any case, stand, or other accessories from your iOS device and see if signal strength improves.
- Reset network settings by tapping Settings > General > Reset > Reset Network Settings.
Note: This will reset all network settings including: previously connected Wi-Fi networks and passwords, recently used Bluetooth accessories, VPN and APN settings.
Many thanks for your tips
I've a wireless doorbell which I've moved & I've also moved WIFI out of the way of the telephone..... Neither have made any difference
I've also reset the network settings.... Still no joy
My previous handset worked just fine, as does my partners so I think its another trip to the Apple Store for me......
Thanks for your help anyway
