I am also getting disconnects (error code 7:11:3:191:101) after patch and maintenance today and after couple of disconnects I have decided to scan my network traffic. When I got disconnected my scan showed that just before disconnection there were some incomplete TCP packets and packet retransmissions and those packets were coming from the same source. I cannot know if this was GW2 or Skype as i had both open at the time.
I have checked my network connection, router settings and log but they all seem to be ok.
Is there anything else i could check?
Edit: After a reboot, the disconnection problem seems to be gone
