Hi all!
I've just built a relatively new pc and i've had nothing but problems with my network!
My wireless wifi works perfectly fine while my ethernet loses it every single time I use it.
The reason this is a problem for me is although my wifi works fine, its very inconsistent with big spikes when I'm trying to play games. Ethernet used to work until it didnt and its just gotten to the point where i dont know what else to do.

For example, Download speeds with ethernet are around 1mbps to 125kbs (i think those are the right units). While wifi speeds are around 40mbps. While using ethernet, my game is very patchy, same as using wifi. To the point where sometimes it is unplayable.

I don't know much but my specs are:
- rtx 4080 msi gaming x trio
- ryzen 7 7800x3d
- Gigabyte b650 elite ax motherboard (which i'm using for both wifi and ethernet)

The games i play are mostly cs and valorant, in which both have issues
So far i have tried:
- a full windows reinstall
- messing around with adapter settings
- restarting and updating router and firmware

so any help is really appreciated! and feel free to ask any questions, ill try and answer as best as i can!
