This sounds silly again. But this is also a common reason why your iPhone may not be able to connect to WiFi. Make sure your WiFi signal is strong and your iPhone is well within router’s range. If you are within WiFi range, you will see the name of your WiFi in Settings > WiFi. Tap the name of your WiFi network to join this network. When prompted enter your WiFi password. Once you’re connected, a blue tick mark appears beside your network name.

Reason 3: Cable not connected to Modem

Well, this may not be obvious but it does happen sometimes. Your router cable may have been disconnected from the modem. There’s no way you can get WiFi signal if your modem and router are not connected. So make sure that you check all cables and connections between router and modem.
