The only drop that wasn't rewired is from the round COX connector box by the sidewalk to the COX box on the side of my house and into the attic area, but all checked out OK. They need to redo that drop as it doesn't run in a conduit and is only barely under my rock, then across my driveway and under more rock to the box on the side of my house. I used to show -1 dBmV to -3 dBmV downstream for awhile but now it varies by time of day and I never get those readings anymore. They also put a new amp/splitter up in my attic.

Looks like upstream bonding was turned off in the area; unless someone in Kenner/Metairie still has it..?? I don't think it's due to the bad weather.

Very good chance they turned it off. They most likely found a problem that needs time to correct, so they turned the upstream bonding off till they get things like they want them. Comcast did the same thing when they first started upstream bonding, they had multiple markets bonding. Then I guess they found issue's, and turned it off for everyone. Then recently over a month or so ago started turning it back on in the markets that had bonding a while back. So more then likely there was an issue/'s found, decided to turn it off because the problem might of affected customers, and being off at this point means a lot less headaches until they get things where they like it.

Sorry to bring back an older thread. But I too had bonding on both up stream and down stream. It was about 2 weeks ago that I noticed it, and just 3 days ago, I'm back to only bonding my downstream. I don't know if it was a test run or I'm having problems, yet again with my service.

Maybe issues were discovered and upstream bond was shut off.

More than likely - my upstream bonding shut off three days ago, around 6AM. I tried resetting the modem to defaults and letting it restart but no more upstream bonding. There must have been something wrong somewhere.

I did notice some pretty inconsistent upstream speeds lately though. After the initial burst of 20-24Mbps upstream the speed was reduced to cap. Then there was fluctuation between 1.0Mbps and 2.8Mbps..it wasn't stable on sustained transfers.

I'm in Metairie if that's any help as to where the bonding is going on.

I wonder how many upstream channels they had before upstream bonding vs after? I mean channels available. For instance, when ever I am on Channel ID 2, which locally is 28.8Mhz, my upload is 2-3Mbps. When it locks on Channel ID 3, which is 32.2Mhz, I get 7-8Mbps. Same symbol rate, and just about same signal levels (seems I get Channel ID 3 when above 41 Tx) but drastically different performances. And I don't mean here and there, I mean without fail. So I assume the signal requirements for the higher frequency are more strict, so less lock on to it, and thus more bandwidth is available? So I would be happy with more channels overall opened up, even if they didn't bond on them yet. However that's probably a less effective use of bandwidth, load balancing vs channel bonding I mean.

I guess my question is; Is DOCSIS 3.0 done the same way across the network? I know it's a standard so it must be similar, but is the way DOCSIS 3.0 executed different in different areas?

AFAIK, on my node, there are 4 upstream frequencies now and I am bonded to each of them. These same 4 frequencies were being pumped through the plant before upstream bonding went active, for quite some time, maybe over a year.

Speeds are still capped at 3Mbps on the upstream unfortunately. I don't know when we'll see any true upload speed increase due to the channel bonding but the burst speeds are insane...I've seen it hit 21Mbps regularly, but it always drops back down to capped speeds within seconds. Hopefully Cox will increase the upstream speed caps.

Don't hold your breath waiting for that[specially if you're in a non competitive area.

Yeah lol, unfortunately I know this all too well...but if the bandwidth is there to utilize, I don't see why it wouldn't be something to do. It seems like a waste of equipment upgrades to channel bond the upstream if you don't plan on increasing speed caps. There was more than enough upstream bandwidth available before, without channel bonding.

But if you don't raise upload speeds that allows you to load nodes even heavier before upstream congestion becomes an issue!
if upstream becomes congested, downstream speeds suffer.

Well there is probably at least a good 4 maybe more upstream channels available for use for internet in your area. I know my area has around 5 upstream channels, which I know about because of a while back having problems with load balancing. Which was causing my modem to bounce around threw all the upstream channels. So channels are there to bond, it just a matter of how many they want to setup for bonding on upstream. Because I am pretty sure when D3 first launched, more upstream channels were added, because of more downstream channels being able to bond, there is a need for more upstream channels being available.

Anything more then one is consider bonding, just because your not locked onto 4 channels doesn't mean much. The people in the LA market were just lucky the cox guys working in there area lit up all 4 channels at the launch of upstream bonding.

6120 modem, I now have two blue lights instead of the one, no speed differences, still 4 channels, etc. Why the two now?

Upstream bonding will ease congestion if it exists on the upstream channel. bonding upstream doesn't mean upload speeds will be raised but it allows for it if provider wants to give more.

Well if its both your receive, and send lights, it means your now channel bonding both ways. So if your Send light is blue that means bonding on upstream.
