Using your own router in the United States
US broadband is not one topology. AT&T Fiber keeps its supplied gateway and uses IP Passthrough; Xfinity can bridge a leased gateway or use a compatible customer-owned modem; GFiber can hand Ethernet directly to your router; Spectrum keeps a cable modem in front; Fios internet-only can use an ONT Ethernet handoff with caveats.
The biggest US distinction: router vs modem
Cable providers such as Xfinity and Spectrum still need a modem or gateway to terminate the provider network. Replacing the Wi-Fi router does not mean the coax-facing modem disappears.
Fiber can still require provider equipment
GFiber explicitly supports connecting your router to its Fiber Jack. AT&T Fiber is different: the supplied gateway remains part of the supported access path and IP Passthrough is the documented way to hand the WAN address to your router.
TV and support can change the answer
A third-party router may work for internet while provider TV or legacy coax/MoCA features still depend on provider equipment. Hlonix lowers confidence where the best available guidance is provider-hosted community material rather than a direct support article.
