Windows 11 Slow Internet

My set up is below:

Tenda Nova node with ethernet connection to the PC.

Upgraded my PC recently and now it appears that windows 11 is throttling my internet speeds to 1MB download, never had this issue before on my old PC. To resolve this, i have to restart my pc or network settings and its fine for 20 mins and then it all starts again. Does anyone know what could be causing this issue? I'm on Skybroadband 400MB and was easily achieving over 100MB download on my old PC.

Check if your connected at half / full duplex

Also check if there is a updated driver for your LAN

Updated the LAN driver to latest, and also on full duplex at 1.0 gbps

Do as @Glanza said. Do you know the make and model of the network adapter used in the PC?

Its a Realtek Gaming 2.5GbE family controller.

Does it still do it with the updated drivers?

Yes, one strange thing I also notice is that speed test on my mobile slows down when my computer is on despite all wifi being disabled on computer

Believe i've located the problem to a dodgy lan cable, never had issues with the cable before on old computer and this one was very intermittent but swapped then over and no more issues.
