Hello @Dominic21 ,

Thanks for reaching out! 

Here are some troubleshooting steps to help resolve this issue:

1. Check your Windows Network Profile:
When connecting to a network for the first time, Windows prompts you to select a network profile (Public or Private). If "Public" is selected, Windows Explorer will not search for other devices on the local network. You can also refer to this link: What should I do if I cannot access printer/internal server after changing the router

2. Verify IP addresses are in the same subnet:
Ensure that both your laptop and the printer are obtaining IP addresses from the router and that their IP addresses are within the same subnet (the router's LAN IP range). You can check this by following the instructions here: How to find IP address on your devices

3. Test network communication with Ping:
Ping the IP address of the printer to verify if your laptop can communicate with it. Follow this instruction: How to use the Ping command

4. Check connection settings:
• Verify that your laptop is connected to the router's main network, not the guest network
• Ensure that the "Device Isolation" feature is disabled on your router
• Confirm that the firewall settings on your printer allow access from the local network

5. Check router security features:
Some security features on the router may block local network access. Temporarily disable features like "Real-Time Protection", "Intrusion Prevention", or "Antivirus" to determine if they are blocking access.

6. Remove other network devices:
If you have other internet devices like Access Points or range extenders, try removing them temporarily to see if they're causing interference.
