Configuring dual Wi-Fi systems to combine internet access from a single modem.
Configuring dual Wi-Fi systems to combine internet access from a single modem.
If you’re open to exploring networking concepts, I’d consider a more hands-on prosumer approach that includes vlans. UNIDO offers a customizable solution or you could purchase a PFSense device as your firewall/router. From there, you’d need access points that support vlans, enabling multiple SSIDs with distinct subnets and facilitating communication between them. This setup would effectively isolate your network. There are numerous YouTube tutorials on this topic, but mastering it usually requires some learning or prior experience. It’s manageable and doesn’t cost a fortune—any old PC from around 2010 can serve as a PFSense firewall, and UniFi APs start at about $100 each. You might only need one, but having two would improve coverage.
You can repurpose old or extra Wi-Fi routers using Steve Gibson's "3 dumb routers" technique. Simply set up DHCP on each device so they each get a unique IP address range. For more details, check out the 2016 episode of Security Now and search online for a summary. LIGISTX also offers reliable guidance.
Technically inaccurate. If routers can block DHCP, disable it. Managing three DHCP servers will become difficult. Using one router with the modem and others via LAN ports on the back is a possible workaround. On most consumer devices, connecting a router to another's WAN isn't reliable. I've primarily used Mikrotik since around 2014. I favor their products. It seems you're planning a wireless bridge between your home and a guest house—this thread might help with setup.
