Advertisements Hi! I've spent a few weeks lurking on these forums and learned a lot, so thanks for that. But I'm having a problem that no one seems to be able to figure out, and I haven't been able to find the answer yet in your threads. After years of having Time Warner Cable's "Starter Cable" tier, we finally upgraded at the end of March to "Standard Cable." (We're near Salisbury, North Carolina, which is the Charlotte metro area.) Not wanting to pay TWC to rent a set-top box or DVR, we decided to get a TiVo Roamio Plus. Our cable line is split two ways at the point of entry (used to be four, but we're not using two of our coax wall jacks, so a cable tech put in a two-way splitter a few years ago when we had a previous issue). Then we have a three-way unbalanced splitter. At first, the stronger end went to our modem, and the weaker two went to the TiVo and a tuning adapter. (I recently changed this so that the stronger signal goes to the tuning adapter.) It's been working perfectly, except we're missing exactly six channels that we're supposed to get in our package: 115 Pivot (Switched) 165 Travel (NOT Switched) 180 DLC/Discovery Fit & Health (Switched) 227 C-SPAN 3 (Switched) 468 Family Net (Switched) 806 AZTECAE (Switched) They all come up with the message, "This channel is not authorized. Contact your cable provider for more information. (V58)". The problem is consistent - it's not as if they work sometimes and not other times. As far as I'm aware, we have never gotten these channels. Here is what we've tried so far: 1) Power cycling everything about a billion times, removing and re-inserting the CableCard, then removing the tuning adapter entirely to see what happened. No difference. 2) Having TWC re-send signals to both the cable card and tuning adapter. CableCard techs say the codes for these channels are being sent and show up on the cable card (I asked them if it could be an account/authorization issue, and they said they checked). 3) Truck roll. They sent a tech with no cable cards, no tuning adapters, and very little experience with either. I felt bad for him. He checked signal levels, and they were fine (not sure how that's defined) coming into the house. While they were on the low side (-7 to -10) by the time they reached the tuning adapter, it's still within Cisco's recommendations. Just to make sure, he swapped the splitter, and then moved the tuning adapter to the stronger side (instead of the modem), so that the lowest we saw on the diagnostic screen was -7... and the channels still didn't work. 4) Swapping out the CableCard. I was optimistic about this, as we replaced a 2008 Cisco PKM802 with a 2015 Cisco PKM803. But the same six channels are missing. They're sending out a third CableCard this week, but I'm not optimistic this time. I don't understand how two cards of different models made 7 years apart just happen to block the authorization of the same small group of channels. 5) A CableCard tech sending a new "TAR file" (?) to the card. Didn't work. 6) Swapping out the tuning adapter. They're both Cisco STA1520, and it didn't work. 7) Calling TiVo. They wanted me to try unpairing and re-pairing the card a few different ways, then replacing the CableCard again, because they say it's unlikely that the TiVo is the issue. When I called TWC back, the guy I spoke with didn't think that would do any good, because we had just gone through that process a day ago when we swapped the card. 8) FINALLY escalating the issue to TWC engineers to check whether there's a problem at the headend. This was Saturday, so hopefully they'll start looking into this tomorrow. 9) Calling TWC again today when I noticed that the tuning adapter was reporting a -10 signal level again. They're sending another tech this week to check for "intermittent" signal problems (which is apparently different than what the first tech was checking for). I'm worried that this will distract them from troubleshooting at the headend ("oh, it must be a signal level issue then") but the CableCard support guy assured me it wouldn't. The TiVo signal level readings are almost always above 90%. SNR on both devices tends to show 37-40. I even got the "SNR might be too high" thing from the TiVo guy, but fortunately he didn't dwell on the idea of there being too little noise... What could we possibly be missing? I haven't spoken to anyone in billing yet, to see whether there could be a problem there. But the CableCard people say the card has the right codes... meaning they know the channels I'm supposed to have. Could it still be a problem with my account/billing codes? (We negotiated ourselves a promotional rate when we upgraded, so I'm nervous about doing something that messes that up.) And if it's a tuning adapter issue, then how is it that one of the channels we're missing (even with the tuning adapter disconnected) is NOT an SDV channel? Also, it may be worth noting that we have a TiVo Mini and want to use it with MoCA at some point. Right now, it's hooked up to an Ethernet cord that runs from our family/living room to the master bedroom... which I keep tripping over.
