2. Try Connecting to a Different Wi-Fi Network

This will help you figure out whether the issue is with your iPhone or your home network.

• Head to a public place like a café or a friend’s house.
• Try connecting your iPhone 7 to their Wi-Fi network.

If it connects: Your home network might be the issue. Try rebooting your router/modem:

• Unplug the router and modem from power.
• Wait 30 seconds, then plug them back in.
• Wait for all lights to stabilize and try connecting again.

Also, check if other devices in your home can connect. If they can’t, it’s probably a router or ISP issue.
