Ethernet detects but lacks internet access
Ethernet detects but lacks internet access
I've had a stable connection for about a week, but it's now experiencing the same problems again. I'm using the router and have reset both the modem and router.
It's unusual to rely on your router as a DNS server, though not incorrect. This setup is common. Are you connected to a VPN? If not, proceed with the steps below.
In the Control Panel, go to Network and Internet → Network Connections. Right-click your connected adapter → Properties. Double-click 'Internet protocol version (TCP/IPv4)'. Choose to automatically obtain DNS or enter your preferred servers (e.g., 8.8.8.8, 8.8.4.4).
Routers often inherit DNS configurations from the modem (when auto-enabled) or rely on settings entered via their web interface. As long as the router is connected to a functional DNS, clients will adopt whatever it uses—whether provided by your ISP or managed by a third party like Google, Cloudflare, Quad9, etc. What type of internet connection are you employing? Does it need support for IPv6?
The router is using its own IP as the DNS server for the host, not the ISP's or any other provider. This won't function unless the router also acts as a DNS resolver and DHCP server, which isn't typical. If the router is set up to handle DNS, it should work even if it's malfunctioning. Avoid relying on restricted services like Google DNS unless you're certain they'll be available.
To modify the DNS server, update your DNS configuration file or use your router's settings interface. For DCHP, adjust the port and port range in your network settings to enable it.
