New iPhone 13 network drop issue

Hi Abhipriya_1009,

Additional information regarding the nature of your concern will be needed to provide specific steps that are applicable. For instance, is this affecting a single Wi-Fi network, multiple Wi-Fi networks, or your cellular network?

If this is affecting multiple Wi-Fi networks, If your iPhone or iPad won't connect to a Wi-Fi network may help as it focuses on the iPhone having issues connecting.

1. Make sure your router is turned on and you're within range

If you're too far from your Wi-Fi router, you won't get a signal, so make sure you're within range of it.

2. Make sure Wi-Fi is turned on and you can see your network

Go to Settings > Wi-Fi and make sure Wi-Fi is turned on. Tap the name of your Wi-Fi network to join. A blue tick beside a network name means that you're connected.

If you see Auto Join disabled under Settings > Wi-Fi > [Your Network], tap the More Info button and then tap Auto-Join.

3. If asked, enter your Wi-Fi password

If asked, enter the password for your Wi-Fi network. Get help if you don't know your password.

Even if you enter the correct password, you may see an "unable to join the network" message or an "incorrect password" message. Restart all of your devices, then try to enter your password again.

4. Check for issues with your Wi-Fi network

If iOS or iPadOS detects an issue with your Wi-Fi connection, you may see a Wi-Fi recommendation under the name of the Wi-Fi network you're connected to. For example, you may see the alert "No Internet Connection". To get more information, tap the Wi-Fi network.

5. Check your cables and connections

If you still can't connect to your network or get online, make sure your router is connected to the modem and turned on.

6. Restart

Restart your iOS or iPadOS device.

Restart your router and cable or DSL modem by unplugging the device and then plugging it back in.

After you've restarted each device, see if you've fixed the issue.

7. Reset your network settings

If you're using iOS or iPadOS 15 or later, tap Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings.

If you're using iOS or iPadOS 14 or earlier, tap Settings > General > Reset > Reset Network Settings.

This will also reset Wi-Fi networks and passwords, mobile data settings, and VPN and APN settings that you've used before.

If the issue relates to cellular networks, If you see No Service, Searching, or SOS on your iPhone or iPad might contain a solution even if you aren't seeing those error messages since it troubleshoots the connection to the network itself.

If only a single Wi-Fi network then working with the network administrator or your internet service provider or router manufacturer would be appropriate as they'd be more well-versed with their network.

Regards.
