We moved to our new headquarters and have Comcast's Metro Ethernet installed.  

We noticed that we weren't getting our rated speeds in the server room, and plugging a laptop into the Comcast device directly, setting Flow Control to off, and the port negotiation to 100 Full Duplex, the laptop pulls a full 100/100 connection.  

We tried that same setup in the server room with the feed coming up from the Comcast equipment, and again, the line is delivering 100/100.  The minute we connect it to the Cisco 7200 VXR, speeds plummet to 1.5 Mbps on both the up and downstream.  

Our Cisco guy on-site says he's used the 7200 VXR with connections much faster than ours, so he's not sure why we're having such a hard time.  In every case, latency is phenomenal, often registering under 10ms to just about anywhere within three states, and not more than 25-30 to New York.  

Anyone have any suggestions?
