Hi everyone! Today I asked my ISP to set up my fiber connection at home (IP address 192.168.17.1). Everything seems fine, it's working perfectly. The only issue is printer sharing. Since the house has two floors, the fiber was installed on the ground floor for convenience. The ISP provided SFP cables and an ONU, giving internet access from outside the house.

The ISP box includes SFP ports that are already set up, plus two extra LAN ports (LAN1 and LAN2). LAN1 connects upstairs to a newer router (10.0.0.1 or 192.168.17.3), which shares with two PCs and also adds Wi-Fi coverage. The other port goes to an older router (10.0.0.2 or 192.168.17.4) – this provides Wi-Fi on the first floor and Ethernet for the computer downstairs.

The problem is my printer is on the second floor and uses Wi-Fi to connect to the upstairs router (10.0.0.1). The computer in the basement can’t reach the printer because it’s linked through Wi-Fi to the other LAN port (LAN1). I need everyone to be able to print from anywhere without extra costs or complications.

Could there be a solution without bridging both networks together? I’m not sure how to proceed and would appreciate any advice! Thanks ahead of time!

The way you entered it should let everyone view each other clearly. It seems the two routers have firewalls active and are preventing traffic. The easiest test would be to turn off both firewalls or switch them to bridge mode if that's an option.

You've shared a simple diagram and are looking for ways to improve network visibility and file sharing between two Windows 10 PCs. It sounds like you're aiming for seamless communication across devices in the same network. The setup involves configuring subnet masks and possibly bridging networks. Make sure you understand how your current settings (255.255.255.0) affect connectivity, and consider consulting a network guide or ISP support if needed.

Needed to switch to the upstairs router in Bridge mode after losing the direct fiber link. Now fiber connects only to the downstairs router, which then splits it through the LAN port to the upstairs unit. It’s not ideal, but it works! Thanks!
