Pc has no internet connection after cold boot but does on first restart. How do I fix this?

On cold boot, my PC doesn’t initialise the internet connection properly. However if I then perform a restart, the internet works fine.

I’ve been operating this way for a few months but it’s pretty irritating having to restart every time.

I’ve tried dns release/renew flush etc., updated Realtek lan drivers, verified windows files (windows 11)

Also turned off fast boot in bios and disabled lan and re-enabled it.

Does anyone have a fix please? It didn’t
