Since I updated to the new dashboard I have had connectivity issues while playing Left 4 Dead 2. I teleport all over the place and cant pick up items. Sometimes I even get disconnected from games. None of this happened before the update. I have my Xbox wirelessly connected to my router and I tested the connection - the connection is ok. My upload speed is .47mbps and my download speed is about 4.9 mbps which is the same before I updated to the dashboard. Since l4d2 is the only online game that I have I cannot test the connection with another game. Is anyone experiencing a similar problem??
