[CATV] channels droppingI'm a new Whole Home DVR subscriber and the past few days i've been noticing that channels are randomly giving a message saying that this channel is not currently broadcasting please check back later. I've mostly seen it on the HD weather channel, BTNHD and also a few SD channels. I've done the whole unplug and plug back in but the same thing happens. I talked to tech support today but they were about as helpful as talking to my front door, they told me to call a toll free #.
Anyone have any idea's as to what is causing these channels to randomly drop? |

Sounds like the boxes are losing 2-way communication and You are then losing Switched channels. Likely a tech visit is all that will fix it if a reboot doesn't help. Do you have Cox Internet? Can you post your TX/Upstream Signal level from » 192.168.100.1 |

Can you post your TX/Upstream Signal level from »192.168.100.1 not all cox areas use SDV it sounds more like a signal issue. |

Posting signals from the modem is apples and oranges. It matters what each unit is receiving, not what the modem is getting.
If you have the Cisco host/clients, press and hold the power button on the front of the unit until the green power led begins to blink, then release the power button and press it again within a second. You should be presented with a diagnostic screen. Then using the remote, use the page up button (not the up button) until you get to a page labeled "DOCSIS DIAGNOSTICS". Look at the values in the upstream and downstream...also the correctable and uncorrectable frames.
Also, on that very first page, make sure you note when the unit booted last, as it starts the counter for the correctables/uncorrectables at that point. |

When you get the "Channel is not Broadcasting" error that is a SDV error message. I asked for modem TX because a house is usually config'd for the modem to have the lowest Transmit power. So if it was really high it could point to the possible issue. |

So if it was really high it could point to the possible issue. The problem is that there is a pattern of installers not knowing the proper way to install for whole home. Mine wasn't done correctly in the least and I suffered for over a year because of it until a senior tech noticed it and corrected. My modem signals were usually about -1db, but all the clients and host were running around -8db on the downstream. It's something that needs to be looked at separate from the internet/modem connection. And upstream transmit power is not nearly as important to WHDVR as the downstream. |

so how do those numbers look that I posted the other day? This morning it was really bad, HD was going back and forth between a great picture, colored "snow" and a black screen.
I unplugged the box and plugged it back in and that solved that problem |
