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).

Jul 25, 2016 11:56 AM in response to supafishby Diana.McCall,In addition to the above, you can check for interference on your network. Download the Apple AirPort Utility from the app store. Be sure to enable WiFi scan in settings. Run it, and ignore that it cannot find an AirPort. Run the scan and look for other strong networks that may be using the same channel as yours. Pick a less-busy channel and update your router settings. The best channels are 1, 6, 11, and any of the 5 GHz channels.
