HHLONIX

Network hardware

Router, modem, ONT or gateway: which box can you replace?

The word 'router' is often used for every box near the internet cable. Compatibility gets much easier once you separate the provider-facing access device from the device running your home network.

When a router-only device is enough

If the provider already hands you Ethernet from an ONT, NTD, Fiber Jack or modem, an Ethernet router can often take over—subject to authentication and VLAN rules.

When a router-only device is not enough

If the wall line itself is VDSL or coax and no separate modem/connection box is present, a normal mesh router cannot terminate that signal.

Why integrated gateways are awkward

AT&T, Xfinity, Rogers and many other providers supply devices that combine access and routing. Bridge or passthrough modes let your own router take over the LAN without pretending the provider-facing function disappeared.

How to use Hlonix

Pick the service profile that matches the physical connection at your address, then pick your router. If you are unsure which access type you have, check the provider account/order details before trusting any compatibility result.
