Hoping to catch SomeJoe's attention... Apologize in advance if these pic's don't come out right, first post.
As I understand the documentation, this is a very noisy line... Remarkably, I'm still pulling 11.5 ish down and 1 up on speedtest.net
What if anything should I look into as far as correcting things?
2nd question on the Channels / Streams tab: I'm running a config as referanced in your section 3, router behind gateway. I have a Dlink DGL-4500 "gaming" router, capable of some limited multicast routing. Just wondering if there's anything that can be done so that I can have my cake and eat it too (see the STB's even though I have a router between my PC and the gateway)... With the capabilities of this router, I would think I should be able to get it working...
Solved! Go to Solution.

Bonded pair - no idea, how do I know?
Extra router - QoS, Dyn DNS not to mention I have much better control over what's behind it than I do with the 2Wire gateway...
Plus I get the added benifit of UV Realtime's "usage" counter by having all my pc's and other devices behind that router.

Excellent idea on the mirrior port, should have thought of that...
Anyway, I just ran pingtest.net's test and got this:
I found a phone # for level 2 support, should I go ahead and call them? Last time I tried to go thru level 1 it wasn't pretty ... Any advice on how to speak with the tech (keywords that should be used) like "premisis tech" and "I&R" or am I just going to sound too petty...

Here's a diagram showing how you can set it up so that Channels/Streams works behind another router.
2Wire RG Coax ------------ DVR/STB #1 Eth 1 ------------ STB #2 Eth 2 ------------ STB #3 Eth 3 Eth 4 ----+ | NetGear | GS-108T D-Link | Switch DGL-4500 +---------- Eth 1 Router Eth 2 -------------- WAN Eth 3 LAN 1 -------- Computer 1 Eth 4 LAN 2 -------- Computer 2 Eth 5 LAN 3 Eth 6 LAN 4 ---+ Eth 7 | Eth 8 ------------------------+
NetGear GS-108T Ethernet port 8 is set to be the mirror port for Ethernet port 1. Multicast packets coming into the NetGear switch on port 1 from the 2Wire RG are mirrored and repeated out port 8, which enters your LAN through port 4 of the D-Link. Your computers can now see the necessary multicast report packets that the STBs sent out, yet no IPTV stream comes to the NetGear switch or the D-Link thanks to IGMP snooping on the 2Wire.
To make sure this works right, it's imperative that the RG's LAN is a different IP subnet than your D-Link's LAN. You probably have already set it up this way, but if it's not, your computers will bypass your D-Link when attempting to reach the Internet. If you really want to make sure nothing can bypass the D-Link, you can also configure the NetGear switch to put port 8 in a separate VLAN with a separate PVID.

A tech will be out this Wednesday to check the line.
So I take it that your UV Realtime does not issue an IGMP join request? It "listens in" for the multicast traffic, is that right?
The reason I ask is that my D-Link 4500 GL supports Multicast (they call it "Enable Multicast Streams") it even reports the following:
IGMP Multicast memberships
Given that the router WAN port is seeing the streams, and I can enable this function, it stands to reason that I should be allowed to see the traffic. However even when I put my desktop into the DMZ (unfiltered all WAN traffic hit's that port) I don't pickup the streams. I'm guessing it's not quite as simple as turning off IGMP Snooping and letting the Multicast get turned into "broadcast" traffic on my internal swich ....
So given that I've placed the desktop into the "unrestricted group" yet I still can't see the stream, the only thing I can think of is that there is no way to disable IGMP Snooping on this router, therefore the only way to see the stream data would be for my desktop machine to issue an IGMP Join ...
Please let me know if I'm off base here. I've got a switch on order, but I figured I'd give this router a go and see if I couldn't find the magic combo ....

I apologize, I just had a chance to skim over your PDF doc and of course, you've mentioned in there that Uverse equipment is not infact issuing a standard multicast join message....
Question: So even if you have equipment that supports multicast (IE the D-Link 4500, or you get your hands on enterprise level equiment that has IGMP Snooping), you're going to get the same results I did, and until you can mirror the port over, does that sound about correct? I'll qualify that by saying that on the enterprise level switch you'd have to disable IGMP snooping thus causing the multicast streams to broadcast to all ports on the device...
It's a bit disappointing, otherwise some of us could have used various equipment to put our STB's behind other devices and layout the house wiring a bit better... oh well....

Update: Premises tech's were out (they sent two). They took my 2wire gateway and ups battery backup for it and walked down to the post in the neighbor's yard and hooked it up out there.
They came back, said they were still seeing the crosstalk on the line, and that they would need to open a ticket with the linemen to get it checked out and fixed.
I kinda felt bad telling him that when I spoke to T2 on Monday to setup the appointment I told them to create the helper ticket then.... Oh well, he says that they will be out "probably tomorrow" to fix the line and that I should be getting a follow up call sometime in the next couple of days.
Side note, they did replace the grounding block on the ATT service box on the outside of the house.
oddly, I think things got slightly worse... Power level is now highlighted in orange in UVRealtime and is at 12.6. Line capacity has increased from 99.6 to 99.9, bits in use went up to 122.9 ...
I admit these aren't huge numbers here, but the summary is that for now, they made things just slightly worse...
Guess I'll have to see what the next couple of day's brings.

Update: 3 calls to Tier 2 and a few tests with "ufix.att.com" I managed to get a T2 who listened to me...
The next set of Uverse Techs were here again this afternoon. This time he tells me that he's un-willing to open a line ticket becuase they get in trouble if they open tickets with line and there are no issues.
So instead they replaced my old original 2Wire Gateway with the new slick looking black one.
As you can see my bit loading appears better than it was with the new router, but I have taken some errors now, and "ufix.att.com" still says I have an issue with my line.
I just can't understand why it is that AT&T own internal Tech tools are reporting "Crosstalk" on the line, yet they are unwilling to fix it.
The Uverse tech out this afternoon told me that his tests did not show any bridge taps, and that all my stats look fine and that I'm in the top 10% for speed in my area ......
I'm totally perplexed....
