This comprehensive guide will walk you through a variety of troubleshooting steps, from the simplest solutions to more advanced solutions.

Common symptoms of Wi-Fi problems
Before we learn the solutions, let’s identify some common symptoms that may indicate Wi-Fi problems on your iPhone:

Basic troubleshooting
1. Check your Wi-Fi network
The first step in solving Wi-Fi problems is to make sure the Wi-Fi network is working correctly. Try the following:
- Make sure your router is plugged in and turned on.
- Check if other devices can connect to the same Wi-Fi network.

2. Reboot your iPhone
Rebooting your iPhone can resolve many temporary glitches, including Wi-Fi problems. To reboot:
