iPhone keeps disconnecting from WiFi

It seems that my 6S running iOS 11 will frequently disconnect from my home WiFi. When I go into the first settings page to see what's up, it will show that no WiFi is connected I then have to go into the next page to see the list of Networks and then have to choose my home network. Eventually, when the phone is sleeping, it will disconnect from WiFi. Anyone have any ideas?


Thanks in advance.

You've probably tried this but if you haven't go into the WiFi settings and find your connected router. Tap on the littie i next to the router's name. First make sure that Auto-Join is turned on. If it is make sure that configure IP and DNS are set to Auto, unless you use a static IP and DNS. After checking all that, I would then tap on Forget This Network at the top of the page. I would then restart the phone and at the same time, reboot the wireless router. Once both are fully rebooted, go back into the Settings>Wi-Fi and tap on your router. You will need to reenter your router password and then join. Again, after you have rejoined that you tap on the little i again and make sure Auto-Join is turned on and configure IP and DNS are set to auto.


If all else fails, you may need to see if your router has a firmware update available.
