isolcpus=7

Note that if you have ~10 ms latency this is not likely to be fixed by isolcpus

Did you install the Realtek DKMS driver?

If you did, what are the current results of the ping test?

I use Ryzen 7 3700X CPU, never had to do isolcpu, it just works. Same on Ryzen 5 3600.

Not that i know of from reading here, but i have never used isolation, ever, i have access to plenty of PC's and laptops so if any show bad latency i run 3D printers from it! :)

also, in step 32 there is an extra : that gets an error if you are cut/pasting the commands.
