HDHomerun Prime missing stations

I am missing just a few stations

SD- 45,49,53,55, 300 thru 309

HD- 1028, 1029,1037,1040,1044,1046,1056,1059, 1300, 1301

I have called for support, but nothing seems to get fixed.

The ST is connected

Authentication    success
Downstream    success
Upstream    success
Operational Status    ready

The cablecard seems to be correct:

Card Manufacturer    Motorola
Card Authentication    success
Card Validation    success
3DES encryption    supported
OOB Frequency    104.203 MHz
OOB Lock    2.048 Mbps
Signal Strength    60% (-24.5 dBmV)
Signal Quality    70% (22.8 dB)
Channel List    tuning-resolver

When I go to a station that works, I get the following:

Virtual Channel    51 CARTOON
Frequency    553.750 MHz
Program Number    6
Authorization    subscribed
CCI Protection    unrestricted
Modulation Lock    qam256
PCR Lock    locked
Signal Strength    69% (-18.6 dBmV)
Signal Quality    81% (32.4 dB)
Symbol Quality    100%
Streaming Rate    2.948 Mbps

When I go to a non-working station, I get the following:

Virtual Channel    53 Syfy DS
Frequency    523.750 MHz
Program Number    10
Authorization    unspecified
CCI Protection    none
Modulation Lock    none
PCR Lock    none
Signal Strength    68% (-19.5 dBmV)
Signal Quality    none
Symbol Quality    none
Streaming Rate    none
Resource Lock    192.168.0.15

Does anyone have any ideas on what is going on?

Your Signal Strength is the issue,  it needs to be greater than -10dBmV, closer to 0 or above would be better.

You need to figure out why or get a tech out to investigate.  Could be too many splitters, a bad splitter, an loose connector, a corroded connecter, a bad piece of cable, or a bad drop cable from the pedestal or pole.

What is the Signal Strength and Power as reported by the Tuning Adapter?

Signal strength from your cable modem would be helpful also.

My signals are not great, but here they are:

I am not sure how to get the Tuning Adapter MTR-700 or Cable modem Cisco DPC3825 signal strength

How many splitters, and what kind, (2-way, 3-way, 4-way) between the main line and the HomerunPrime?

Has a Cox tech been out to check your signals?

Couple of years back I had a low signal issue that made on-demand not work.

Tech came out and repaired issue. Sounds like I might need them to come out again.

Wall to 3 way spliter

One to cable box

One to cable modem

One to two way spliter

From two way spliter

One to TA

One to HomerunPrime

Your Cable Modem Signals are also very Low.  Definitely schedule a Cox Tech to come out, unless you are capable of trouble shooting the cable lines and replacing the splitters.

If you could run a single cable from the drop to the cable modem bypassing all splitters, then check your Cable Modem Signals, the Signal level should be approx 7 to 10dBmV.  No negative numbers.

You may end up needing a Signal Amp.  But that should only be the last resort, after Cox has replaced all the cables and splitters and attempted to rebalanced from their end.

Thank you very much for your help.

I don't have any option, but to use splters, but I will use the single cable drop for testing.

I am going to replace some of the internal coax and splitters and see if that helps.

Any suggestions on what type of spliter I should use?

You can just go to a Cox Store and ask for new splitters, I would stay away from anything from a retailer like HomeDepot or Walmart. Commscope are good,  But if you are going to have a Cox tech out, don't bother.

Well, I replaced the splitter going from the TA and the HDHomerun and that helped a bit.

Yes, I recieved a bad splitter. I did not realized these go bad.

Getting 100% on the signal now, but I am still missing stations.

Does not-suscribe mean that the cable card does not have all the programing?

Have you rescanned channels using the HD HomeRun Set-Up since improving the Signals? This is most likely the issue.

Even an Authorization: not-subscribed should still list the Signal Levels and Frequency, See below, I do not subscribe to Cinemax or Starz. This could still be a signal Issue, or It could be the Tuning Adapter does not have all the channel mapping.  Have you Rebooted the TA since improving the Signals?  You may need to call Cox 877-820-8202 and ask for a Hit to be sent to the CC and TA, and perhaps ask to have everything Re-Paired.

Yea, i did multiple scans but still got the same issue.

I ended up calling Cox and they did a hit on the TA and some, according the the rep,  "magic" to the cable card.

and..................finally.................everything works!

Again thanks for your help.

Getting the signal to 100% was the key, but Cox still had to do a hit to the TA afterward to get everything working.
