Two networks connected to one ISP
Two networks connected to one ISP
Consider setting up two fully separate wireless networks. Option one involves a managed switch with VLANs per router and using modems as trunk ports. Option two uses a VLAN-supporting router, converting each wireless router into a standard access point on its own VLAN. I prefer option two with the TP-Link ER7206 Multi-WAN Professional. It offers multi-WAN capabilities, increased capacity, firewall protection, and integrated load balancing.
