This is an important step, because you can localize and isolate the problem between the router and iPhone. The easy way is to connect your iPhone with another router if you have. If your device works on other Wi-Fi routers, then the problem is very likely on your router. In this case, you can restart the router to see whether that helps.
Disconnect the power cable to your router and reconnect again. You also need to check all of the connectors and cables are working fine. Go to “Settings > Wi-Fi” and tap on the info icon next to your wireless network.
Note down the IP address against “Router”.
