Let's eliminate a couple of common causes for most issues first. Here are three recommendations:

  1. Disable IPv6 on your AT&T provided router/gateway - IPv6 is enabled by default and can cause a slow network and other communication issues
  2. Change the Ethernet port configuration for each port on your AT&T provided router/gateway from Auto-detect to 100BaseT/Full Duplex - This will eliminate auto-negotiation incompatibilities
  3. Use Google DNS (8.8.8.8 and 8.8.4.4) on your devices but retain DHCP

You state the issue is with packet loss from a "streaming server."

  1. Can I assume you are referring to video streaming?
  2. Are you streaming from one server to another or from one server to a PC?
  3. Is the packet loss only associated with the Raleigh server?

As you can tell by my questions I am looking for more technical information on how this is set up.

I wont be able to check those until this weekend but doubt if it has anything to do. Seem like you are screw if you have routing/performance issue. All tech can do swap modem and you are on your own. 

This is radio streaming of 64kps only.   My gateway ip 172.2.200.1 (i think) have very high latency which i think its next hop to the router.

I am sending stream to the server from Raleigh and its breaking/timing out. same server works with zero issue from another uverse location in ATL.

True, unless there is an issue between your server and the first hop in your neighborhood, latency and packet loss problems are impossible to resolve. The primary reason is that it is the Internet and not just under the control of one company. Secondarily is that your connection is shared with others in your neighborhood.

 

Your experience could get worse in the future as IPv6 becomes more pervasive. IPv6 has a lot more control information within each packet that will determine the importance of a packet reaching its destination and if there is congestion, a packet with low importance will be discarded and sender will have to retransmit. Packet discard occurs today with IPv4 but it is random and  in-discriminatory.

 

172.2.200.1 is listed as being located in North Raleigh and my pinging results from the other side of 540 ranges between 22 and 30 milliseconds.

I  just disable IPV6 and change the LAN port to 100BaseT/Full Duplex. I will report back if that helps or not

where do you update DNS? i cant find it

 

port 3 is where my system plugs in.. see high discards.  how do i reset this counters under LAN statistics?

Please replace the Ethernet cable in port 3 with a new store bought Cat6 or high quality Cat5 cable.
