Hello my boyfriend just moved in and he plays on his ps4. I play on the pc and for the past few days it seems that when he logs in i get DC'ed and a 90002 code. i will have him log out and i can log in and have no problems till he logs back in.

this is a bandwidth problem?

we are both wireless.
would it be better if i was hard wired?
could it be a driver or port problem?
or is his ps4 just better ><

any help would nice thank you
