I currently have a bridged connection with my laptop and xbox. I am able to connect to Xbox live, no MTU errors. ISP says no ports are blocked. I, however, get kicked off xbox live frequently and cannot connect to Black Ops II Multiplayer, as it says "Servers are down", which i know are not. I tried using an alternate MAC as well and still the same issue occurs. No connectivity to multiplayer. I will be in this hotel for months for work so i need to get Xbox live back and running, please help.
