Redundancy is a wonderful thing...

I upgraded all of my HDHRs to 20250623 (I usually wait a month or so before I apply vendor software/firmware upgrades, in case any issues are found). Everything seems to be running perfectly, and the SignalStrengthDBmV field is returning values to one decimal place for my dev units. Thanks for the ...

I'm curious how you were able to prove it was the power adapter before you even ordered a replacement...

A word of caution, though. Depending on what the purpose is for the secondary router, it might not be appropriate to enable bridge mode. For instance, if the OP is using the secondary router to isolate IOT devices from the rest of the network, enabling bridge mode would defeat the purpose. A guest ...

Could be a bad power adapter, SiliconDust sells replacements.

One of the main purposes of a router is to block unwanted incoming WAN port traffic from getting to the LAN port(s). There are various ways to loosen the restrictions and allow some or all traffic thru to the LAN ports. Having more than one router in a home network is not typical, and requires an ...

Well, the problem with the second Prime/HSC device has been resolved, yay! Now I am back to how I was before the HSC conversion began, and only had to spend a combined 7 hours talking with Spectrum CableCARD support and working with Spectrum technicians in my basement. Ironically, there was not a ...

Comparing some of the Prime webgui screens between the functional and non-functional units, I notice the UPM Address looks to have a legitimate value (0x0309F4) for the functioning unit. The non-functioning unit has a UPM Address of 0x000000. Could that be some or all of my problem?

Device ID is 13256C0B. I just initiated a channel scan on that device.

Spent 40 minutes on a phone call with Spectrum level 0.5 cable card support this morning. He claims that there is no difference between how my working device and my non-working device is set up on their end. They're rolling a truck for Thursday morning. Yay...

Fortunately, my other Prime is working ...

That was a great idea, I hadn't thought of that. I went ahead and installed a different cable, with the same end result. One thing that I did notice, however. When I looked closer at the HSC channel map, it is including channels that my Spectrum plan does not get (HBO, Showtime, Cinemax, etc.) The ...

OK, so the plot thickens. I had seen the View Channel Map link, but had never clicked on it because I assumed it would be identical to the channel map in the Prime. But when I clicked on it just now, there is 57 pages of channels, which matches the HSC channel map for the working Prime. So now I am ...

Now that one of my two Prime's is working well (after the HSC migration), I have turned my attention to my other Prime. After connecting the second HSC device to my Prime, and waiting close to 12 hours (with a power cycle or two mixed in), the webgui for the Prime looks good:

Status (on main menu ...

That seems plausible, thanks. I was able to get everything working in my SageTV environment, looks like they have not transitioned yet to MPEG4, the files are still MPEG2. Anyways, thanks for all of the assistance!

leerandall, I just timed a few channel changes within the Windows HDHomeRun app, mine are taking 4-5 seconds. I didn't measure my channel change time when I was using a tuning adapter, but it feels like it's about the same.
