Interesting regarding X1 boxes being stream boxes. I had no idea.

Back to the actual problem.

Jason/Ned - can you show me where I can view these logs that show the connection issues? I'd love to call Comcast and highlight this problem to get it fixed. If they are backend logs that only SD folks can see, can I get a technician from SD to work with a Comcast Cable Card specialist? I'd be happy to arrange. While I can appreciate the issues may dry up at some point, simply telling your customer that reasoning isn't a good customer experience. I'd be out of a job if I told my users this logic. In these scenarios with multiple companies pointing fingers (I have plenty), I get both of them on the hook until it's resolved.

I'm just asking to continue this journey so we can resolve and my TV viewing will be perfect like it was before.

Thanks!

Jason/Ned/Nick - please - I'd love to close this out. I literally cannot watch/trust Live TV or my DVR anymore. Can I get answers to my previous post so I can close this out?

I don't believe the timeouts are logged anywhere user-facing.

There's nothing to be gained pursuing it with Comcast. There are no CableCARD specialists, just the same old CSRs everyone deals with. At best, they know how to do a basic setup of a card, validating it and authorizing it for the channels. Anything beyond that they're going to roll a truck, and the tech there isn't going to know anything about CableCARDs either. They'll measure signal levels, maybe replace the card again, and pronounce everything fine, and send you a bill for $75 for their trouble, and nothing will have changed. The only people who might actually be able to do anything about it are headend engineers, and there are about 8 layers of people between them and customers and you simply cannot talk to them, and we can't either.

I do have a couple of connections at Comcast that I can try to tap, understanding the difficulties. Would you be willing to share these logs if I can make this happen and talk to them?

I can't just simply dismiss this though because it is impacting our DVR'ing and Live TV watching. These issues are basically rending the system faulty and unreliable. If we can't get past this, I'll be left with no choice to abandon this system which I have supported and love for so many years now. I just don't want that happening.

And I personally don't feel these timeout issues are my problem. I'd be having problems on every channel if that was the case.

I have seen similar issue....

At my house.... I have a prime with Comcast service... From what i remember fire stick would not play any hd channels and would stutter on sd channels usually after commercial. I bought a couple nvidia shield devices and only use them at my house and have never seen a stuttering problem ever again.

At my moms house.... I just installed an extend two tuner and it is connected through her wowway cable services and all the clean qam channels appear to work but will begin to stutter intermittently. All of the clear qam channels are sd not hd and all of the devices are the small fire tv 4k square boxes.

The fire tvs never have issues streaming from youtube or Amazon Prime or anything else I've thrown at them.... Only stuttering from video transmitted from hdhomerun devices


Perhaps leads me to believe the hdhomerun is not generating a proper video stream that the codec and decoder in a fire tv can handle

The problem is that the HDHomeRun doesn't generate the video stream, it just relays whatever data is sent from the cable TV provider. That makes problems like this very hard for us to get a tackle on, because not only can it be unique to a specific playback device, but it can be unique to a specific cable provider. For example, I haven't been able to replicate this issue using Comcast on my PRIME when using a Fire TV 4k stick, but we know it is an actual issue for others.

The HDHomeRun sends a cp_valid_req APDU to the CableCARD once per minute. Most of the time, the CableCARD responds within the allotted time. Occasionally it doesn't, usually 10, 20, or 30 minutes apart. We don't have any kind of access to the inner workings of the CableCARD or cable provider system to know what it might be doing to have issues at those times.

Jason, I'm seeing others that are having network issues with Wemo "Smart" mini switches. I have a TON of Wemos and it was part of the "upgrade" in my move. Do you believe from what you saw from others this could be related? So far, I have shut down all my minis to see if I can see a visible effect.

I have some Wemo wall switches I cannot turn off.

Yes, it could be related.

After a few days of testing the issue seems to be GONE. So it is related. I am going to give it a full week before I declare victory.

I highly suggest you put out a bulletin to your users about the Wemo mini plug. It seems the fix is disabling UPNP on your router which I believe will have no effect on what I use in my home networking, but I can see whereas others will not be able to do this. I have not done this yet. After my full week, I will plug in the devices and disable UPNP to see if I'm good.

Also suggesting you add steps for a network trace for your difficult situations like me.

I appreciate you and the team staying with me on this one.

Just following up. I've had no to little issue since disconnecting the Wemo Smart Mini Plugs from network. My Wemo wall switches remain online and do not seem to affect network traffic. I've looked through Belkin's forums and there doesn't seem to be a solution that works to make the plugs not so talkative on the network. Turning off UPNP doesn't help.

I'm in the process of migrating only the minis to TP-Link (Kasa).

More to come...but again, highly suggest some sort of bulletin or added to the standard questions you ask for people with issues.

Just to close this out, no more issues. Wemo Smart Plugs were the culprit.
