I am using U-Verse Realtime version 1.9.1.0. I have attached a screenshot of the Coax/HPNAscreen. I have the RG connected to a splitter via RG6 coax and from there to three remote STBs via individual RG6 coax runs.
On the attached screen shot there are four source IDs listed each having three destination IDs associated with them. Per the Users documentation for this screen I am can rename the sources to easily identifiable names. I want to do this but I have to identify the sources. The notes say to identify the individual sources I should disconnect the coax from each STB, one at a time, and see which source disappears from the list. I have removed the coax from individual STB boxes and waited the indicated five minute update time (and longer). However, the screen remains as you see in in the attached screen shot. The disconnected STB coax does not disappear from the screen. The disconnected STB does disappear from the Channels/Streams screen. I am trying to identify the coax runs with the low PHY Rate.
Am I reading the documentation wrong or am I doing something else wrong? Any ideas?

Yes, I tried closing and reopening the Realtime program several times without success. However, I did find I could get the disconnected STB to disappear by running the Extended Test in the Home Portal program. I could see the source drop to zero there and then when I relooked in the Realtime program that source had disappeared from the screen. I did this with each of the STBs to identify them. I assume the remaining one had to be the RG. Is that correct?
Also, one of the PHY rates cleared up. The coax connections were all tight at the STBs and it took a wrench to loosen them. There may have been an issue in the coax shield/braid connection to the connector or the center conductor had tarnished or something. I have had to switch a port on the splitter on two occasions to get a lost signal problem fixed a year or so ago. I may need to get a new splitter but I will loosen and retighten the fittings there too.
The new screen shot is attached. Why is there any data flowing from TV-Basement to TV-Master BR and return. I don't understand this. Do the STBs talk to each other for some reason?

HPNA/COAX distribution must be perfect -
One piece of cable - no barrel connectors.
Compression fittings on cable ends. Tight connections.
No distortion of cable profile (stapled) or sharp bends
att splitter - all ports connected to correct connections.

I have done a lot testing to see which coax run may be causing the results on the attached screen shot. It appears that the run from the splitter to the Master BR STB is the culprit. It is one piece of 30 feet of RG6 coax with compression fittings and no barrel connectors. It is the only run not installed by the U-Verse installer. He reused this run, left over from a previous cable TV installation but did put new fittings on the ends. I can remove this run at the splitter and terminate that port on the splitter. Then all remaining sources show a 112 PHY rate.
The splitter that was installed with U-Verse was a Tru Spec TSB-41G. No AT&T markings on it. It has a fourth port that is unused. I found that port is open. No signal on that port at all. I asked technical support if they needed to replace the splitter or could I just go buy a new one. Their response was that they didn't replace them and it was OK to do it on my own. I'm not sure what to think about that but I went looking for a splitter and I have not found one yet with DC blocking on all of the ports. The TSB-41G does have DC blocking. Personally I feel more comfortable with DC blocking just to avoid any voltage loops anywhere that might show up. Does anyone know if DC blocking is a requirement?
Being a purist type, I would like to see 112 PHY rates on all of the coax runs but I cannot detect any operational problems. Perhaps that coax run is on its way to old age and should be replaced.

Appreciate the update.
