Computer connecting to router but not Internet

Starting with hardware

Telus purefiber modem (in bridge mode)

Going directly to tp-link Deco xe65 pro (2 in mesh)

Problem computer

Linux Mint software

Ryzen 5800xt

Msi b550m

Nivdia 3070

Usb Ethernet adapter, 10/100/1000/2.5/5 with a realtek chip

I recently moved and I have one computer being stubborn and not playing nice with ethernet, wifi works fine on the computer. Tried onboard and with the usb Ethernet adapter, both don't work. Ethernet Worked fine on my old shaw 1g over coax system.

Cords and usb Ethernet adapter have been tested with another laptop (running the same version of Linux), no issues. I have tried different ports, like off the router, off the modem, and off a switch. No changes.

I tried manually setting up up addresses, mac address and DNS settings in both my Deco settings and on the computer. I can now see the computer as a device in the deco app, and it says it's connected. But it has no internet access.

When I try to ping the router or Google from the computer it says something along the lines of destination host not reachable.

I don't think it is a computer issue because the computer is detecting and saying the ethernet is connected. Drivers and stuff say they are correct.

I have been fighting with this for a couple hours a day, hunting on Reddit and other forums for answers or things to check. Thought I would come here for ideas.

Everything has been updated and restarted multiple times as well. I am not well versed with networking but I like to tinker.

Thanks
