Q: Iphone 5S won't connect to any wifi, won't connect via 3G/4G

Iphone 5S, purchased from Apple Store about 1.5 years ago.  OS 9.3.2

 

Suddenly won't connect to home wifi.

 

Has the blue tick next to wifi name.  Looks like it's connected.

 

Have turned it and router off/on.  Have reset network settings.  Have done that thing where you turn phone off by holding down home key and off key.

 

Phone also not working on 4G data plan.  So the only thing that works is the telephone.  Discovered when I went out that it won't connect to other networks.

 

Been through the support pages and haven't yet tried tinkering with the router, because I'm in Spain and not sure what I'm doing.  Tried making genius bar appointment but nearest appt is in 4 days time.

MacBook Pro with Retina display, OS X Mavericks (10.9.5)

    Below is a User Tip about Wi-Fi issues. Suggest starting from the top and working down. Maybe one of them will help.

     

    1) Perform a Forced Restart:  Hold down the Home and Wake/Sleep buttons at the same time for about 15-20 seconds until the Apple logo appears. Allow device to restart.

    2) Reset Network Settings:  Settings > General > Reset > Reset Network Settings. Rejoin the Network again.

    3) Reboot Router/Modem:  Unplug from power for 2 minutes and plug again. Update Router Firmware (check manufacturer’s support website for a newer FW). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (20 MHz recommended for the 2.4 band).

    4) Change to Google's DNS:  Settings > Wi-Fi > Click on the Network, Delete all numbers under DNS and enter 8.8.8.8 or alternatively 8.8.4.4

    5) Disable device prioritization on the router if this feature is available. Also disable any VPN apps and test Wi-Fi again.

    6) Determine if other Wi-Fi devices on network are working well (other iOS devices, Macs, PCs).

    7) Try device at another Network, i.e., neighbors’, public coffee house, etc.

    8) Backup and Restore the Device using iTunes (ask for additional for details if desired).

    9) Go to an Apple Store for hardware evaluation.
