2 edits | Switching VDSL connection from Coax to RJ11
The U-verse tech replaced my NID, and installed a new "filter" that has coaxial output. He ran coax from there to the RG (it's maybe 2 feet away, right on the other side of the wall, so distance or wiring quality is not an issue).
In my setup, the TV works fine, but the IPTV funneling through my D-link DGL4300 seems to overload the wifi portion of it. So I wanted to try using HomePNA to it with the coax line instead.
Whoops, the coax line is in use by the VDSL. I presume to use HomePNA your VDSL needs to be connected on the RJ11 side. Is that true? Or is there some sort of splitter you're supposed to use (which can't be a good thing for the VDSL signal...).
OK, so I tried making that connection to the "unfiltered" test jack with the included green CAT3 "Data" cable. RG doesn't sync that way. I tried completely disconnecting the bauln so I'm left with a perfectly typical incoming line->protector->test jack setup and it still does not connnect.
How does the NID need to be configured to make a "straight" VDSL connection? I have no POTS so that is not an issue.

| First of all that is bad on the techs part. The connection from the NID to RG should have been done with Cat3 or Cat5e.
Someone should be able to answer it. If you don't want to do it call support up and they should be able to get a tech today or tomorrow. |

Some where in the 3800 gui there is a page with a "DSL Line Selection" drop down box, have you tried that? |

This would be the link for what wayjac is talking about.

| I figured it all out, I guess the test jack isn't connected to anything on the telco side. I connected the line to where the bauln was connected to, and it syncs up. Max capacity went from 42mbps to 49mbps.
That's impressive. I'm pretty far from the VRAD at about 2700 feet, measured in driving distance.
That freed up the coax line for HPNA, which works, and now my other wifi router isn't going crazy. Much much better.

1 edit | Good to hear. I am about 2069' from the VRAD distance (get about 62-65mbps) wise, measured to the NID. You are correct test jack does nothing at the NID.
That is bad that the tech hooked you up via coax. |

Yeah especially since he knew there was absolutely no need to. Running the CAT5 phone cord would have been just as easy. He instead passed a 6 foot coax cord through the wall and hooked it up to the RG! 
I'm probably now missing the POTS filter you're supposed to use in this configuration, but since I don't have POTS it hopefully won't matter.

said by djrobx  :... but the IPTV funneling through my D-link DGL4300 seems to overload the wifi portion of it. So I wanted to try using HomePNA to it with the coax line instead. That is your problem right there. Your DGL is not designed to handle the IGMPv3 messages being sent, nor can it do multicast filtering along with the IGMPv3 snooping the RG can do. Make sure your STBs are plugged directly into the RG and your problem should be fixed.

Or is there some sort of splitter you're supposed to use (which can't be a good thing for the VDSL signal...). HPNA would fix your problem because the STBs would be plugged into the RG. It would have the same effect as taking the Cat5 cables from your DGL and moving them to the switch on the RG. You can have both VDSL and HPNA running on your coax line, you would need a diplexer though to do it. |

| Yup. I'm using the DGL as Gigabit Switch+Access point by disabling DHCP. I'm not using the router features of it (WAN port is unconnected). Whenever you'd play something on the DVR, all of the ethernet lights would go nuts.
But I think its "router" function still saw all of the multicast stuff occurring outside of the local subnet, and it might have trying to route or firewall some of it. There were entries in its log about "spoof IP attacks".
Ultimately I came to that same conclusion as you - a direct connection to the RG would be better. Had the tech not used up the coax port for the DSL, it would have a snap since the cable box used to use the coax there, and the other end of that coax is at the RG!

| However, the HPNA interface is bridged with the Ethernet switch. So if it works putting them on the HPNA interface, then it should also work putting them on the Ethernet switch.
So, if your DVR was on the switch built into the RG, things behind the DGL still saw the activity? |

| The RG is at one end of the house (where all the wiring comes together). There is also a 5 port Gig-E switch there. The Gig-E switch goes to all the rooms in the house. In the livingroom, there's the DGL-4300. The DGL acts as a Gig-e switch for the computer (which is why I need Gig-E there), XBox 360, and PS2, and provides wifi access in the livingroom.
The U-verse tech assumed it would be OK to just plug the ethernet in there. It worked fine, but caused all of the DVR traffic to go to every machine in the network because of the lack of igmp and filtering intelligence you mentioned. 
I just wasn't sure if the RG was smart enough to stop broadcasting everything to other ports on its network if I used the HPNA. It is, so now everything is happy again. |
