Dear Concern,
I am using iPhone 5s and recently I have updated my OS and got iOS 10.0.1. But I am experiencing slower Wi-Fi speed and my apps not working properly. My other device (Laptop and others smart phone) running smoothly as before.
Please provide feedback. Thank you....Adrian
iPhone 5s, iOS 10
Below is a User Tip about Wi-Fi issues. Suggest starting from the top and working down.
1) Restart you device. If a normal restart does not help, hold down these buttons at the same time for at least ten seconds, until the Apple logo appears: a) the Sleep/Wake button and the Volume down button (iPhone 7 and iPhone 7 Plus) or b) the Sleep/Wake button and the Home button (all other models)
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). Channels 1, 6 or 11 are 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. Try restoring as New first and testing it. If ok try restoring the backup (the backup could be corrupted).

9) Go to an Apple store for hardware evaluation. The Wi-Fi chip or the antenna could be defective.
