There really does seem to be issues with connections with 808 recently as even my wallet has been dropping active connections on a regular basis when before I always had at least 8 connections all the time. I currently just have 2 active connections even after add fresh nodes each day so there must be an issue somewhere as many people are having these problems.
My wallet currently has 12, no problems here with dropping connections. Daft as it sounds have you tried rebooting the PC and router?
