ISP has stayed the same, XFinity. I just changed from using a netgear modem/router combo to using the xfinity advanced gateway. No pattern noticed, can be in instances, just sitting in a zone, whatever. I did put the gateway in bridge mode and that seemed to clear up the problem, I was able to queue for Palace of the Dead and get through level 41 to 50 before we wiped to the boss. Has anyone else used the XFi gateway in bridge only mode with any luck? I want to know before I go buy a new router for WiFi if this will work.
