I have a Ethernet ran into my computer and for some reason in games (smite and over watch). I randomly get disconnected, however my internet is fine, I am in skype calls whilst it happens. I have no idea what it is, however I know it is not the cable (cat7 cable, dont ask why). And I do not believe it is the router because it is a netgear N600 ( I think) and the modem is a SB6121. Not sure the specific models but they seem to be decent gear for internet.
