Step 2: Click on Printers and Scanners from the left menu. Then, click on your printer name from the right pane.

Fix 3: Disable Wi-Fi Isolation or Segregation on Router

AP Isolation is a great way to prevent unwanted hacking of your wirelessly connected devices. But this also means that it can prevent wireless devices connected to the same Wi-Fi from communicating with each other.

Step 1: Open your web browser and enter the IP address for your router.

You can find the IP address by going to System Settings > Wi-Fi > Details and you will see the router IP address.

Step 2: Sign in to the admin panel of the router and find the option of AP isolation.

Step 3: If the setting is enabled, disable it and restart your router.

Once done, connect your printer again to the network and check if the problem is solved.

Step 2: Click Printers & Scanners from the left sidebar. Then, select your printer from the right pane.
