Frequently Asked Questions

Why does my ASUS router keep showing WAN disconnected?
Recurring WAN disconnection usually indicates a failing ethernet cable, loose connections, ISP service instability, or outdated router firmware. Try replacing cables and updating firmware first.
Can I use WiFi when WAN status shows disconnected?
You can connect to your router's WiFi network, but you won't have internet access since the router cannot reach your ISP. Local network features like file sharing between devices will still work.
How do I know if the problem is my router or ISP?
Connect a device directly to your modem with an ethernet cable, bypassing the router. If internet works directly but not through the router, the issue is with your router. If neither works, contact your ISP.
What WAN connection type should I use for my ASUS router?
Most residential connections use DHCP (automatic IP). Some DSL connections require PPPoE with username/password. Contact your ISP for the correct connection type and any required credentials.
