When I tried out some of the reliable solutions, one of them succeeded in fixing the WiFi problem on my iOS 12 device. Hence, my run with the latest iOS iteration has returned to the fast lane.

Check Your W-Fi Router

At times, Wi-Fi Router could also be the culprit behind the network issues. So, give it a fresh start.

Try turning off your WiFi router and then unplug it from the power source. Now, grab a cup of coffee and wait for about 10 minutes. Then plug it back in and reconnect it to the power source.

Note: Try connecting to another Wi-Fi network, if it’s available for you. If you don’t hit any roadblock while using other networks, your WiFi connection will be at fault. Hence, I would suggest you talk to your network provider.

Give the WiFi Network and Your Device a Fresh Start

Disconnect your device from the Wi-Fi, reboot it and then reconnect to the network.

Step #1. Launch Settings app → Tap on Wi-Fi.
