Hey.

Sometimes i have micro cuts in my PC of internet (only in the pc, bc in the ps4 when this micro cuts happens it works fine)

I have the PC with Ethernet, tried 4-5 things of internet and no one works.

any idea what can it be?

Ive changed the ethernet aswell.

Try swap ps4 and pc ethernet cable. Maybe 2nd one was bad too.

Did it, I think it was my drivers. reinstall them and i didnt lost internet for 3h when b4 it was every 20mins
