GoKawiilFixing double NAT: bridge mode vs access point mode for home routers
When a home network has both an ISP-supplied gateway and a personal router or mesh system, leaving both in default settings can create double NAT, since the ISP gateway keeps routing traffic even when connected to another router. The fix is to either put the ISP gateway into bridge mode so it stops routing, or switch the personal router into access point mode so it only extends Wi-Fi while the gateway keeps routing.
GoKawiil's interpretation of the reporting above, not reported fact.
Double NAT can cause connectivity problems for gaming, VPNs and some smart-home devices, so understanding this distinction helps users troubleshoot flaky home networks. The choice also matters because access point mode disables many advanced router features like VPN and QoS, meaning users who bought a router for those capabilities should use bridge mode instead.
- Running an ISP gateway and personal router together in default settings can cause double NAT issues.
- Bridge mode disables the ISP gateway's routing function, letting your own router take over.
- Access point mode keeps the ISP gateway as the router but disables extra features on your own router.
