So I have been encountering these lag spikes and disconnection errors. I honestly hadn’t paid attention to the error numbers because my lag spikes and disconnects were occurring only once a week if that. Now it is every day. A google search brought me here. But it’s worse for me. The second I get this error every machine on my network drops off momentarily. I called my ISP because I figured they may be having trouble. I replaced the router and hooked direct into the modem. Same issue. A technician came out and was unable to find any noise in the line. Modem and router tested properly. But still. My ENTIRE connection will disconnect sometimes with this error 7. Kind of odd.
