Ethernet not working… can't reach DHCP server?

I recently moved and got a new router. Everything was fine for about a week, but now when I turn on my PC, I get the ‘no internet access’ symbol and a message saying ‘can’t reach DHCP server.’ I’m using Windows 11. Any ideas on how to fix this?

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

You’ve not given much detail. Did you try rebooting the router? Are there any specific error messages?

What troubleshooting steps have you taken, and what were the results?

Yeah, I rebooted the router, power-cycled it, and checked the modem. The issue isn’t with the router because I connected the ethernet to my old computer in the same room, and it worked fine.

I tried setting a static IP and DNS, but still no luck.

Whenever I try to flush DNS or renew, I get errors or it fails in the command prompt.

The DHCP server is part of your modem/router. If it can’t be reached, it could be due to a loose cable, a damaged cable, or a router that needs a power cycle.

I’ve already checked all of that.
