Hey all
Last year I asked around about help regarding setting up MoCA in my home with a very weird and not at all ideal network topology. Eventually I managed to get that to work by replacing the amplifiers with a rare sort that explicitly bypasses MoCA signals, the PDI-MBA-101-A. (In general amps today do not seem to bypass MoCA even if they are branded 'MoCA' in some way.)
In any case. That is all in the past. I decided I was sick of the old RNG150 boxes and DTAs and that we should move to X1. In accordance with that, they found and removed almost all hidden splitters, save one in the attic, and had all lines otherwise come straight out of one amplifier.
Now. The MoCA bridges are Actiontec ECB6200 bonded-channel models, and we were outfitted with 1 XG1v3 DVR, 1 XG2v2-P box, and 4 XiD-Ps. While those boxes work,
1) the fact that the XG1 and XG2 boxes' firmware has MoCA set to use version 1.1 rather than version 2.0 makes for a maximum speed (which I only got a few times) of 100Mbps down;
2) after some actual use of the boxes (*not* while they are being used, but after they have been - see #3 below) the maximum bandwidth decreased again, to like, 40Mbps and even worse,
3) while the boxes are in use - even if just for live TV and not anything else that would require the boxes' MoCA connection (e.g. the DVR), speedtests decrease even more, to about 25Mbps - no better than a marginal powerline-based network - and regardless of the speedtest, internet delivered over MoCa remains too spotty to use: Netflix stays on SD streams less than 1Mbps large, Plex needs to transcode to a very small stream, etc.
There is nothing in the cabling that could be causing this, to my knowledge. Unplugging all the X1 boxes and leaving the Actiontecs in yields full bonded MoCA speeds. One of the bridges is sharing a spot with my modem (the coax comes out of the wall, goes to the bridge, and then goes from the bridge to the modem) which worked without issue before: I got full 240/12 down speeds on my modem and my MoCA speeds did not suffer either. The other bridge is next to the XG1 DVR, but the passthrough function didn't work (again, it did with the first bridge and the modem) so I put a known-good MoCA-rated 2-way splitter there and had one output go to the DVR and one to the ECB6200. Again, as long as I unplugged all X1 devices, MoCA worked at full speed.
Checking the ECB6200 settings - they are at their defaults, of 1150Mhz/Band D Extended. This is reputedly the only setting that works at all. I did try using different bands but this deteriorated speeds and performance whilst actively using X1 boxes even more severely.
I can't be the only person who wants to use MoCA (particularly bonded, but really any sort) for home networking, while also using Xfinity X1 boxes. In fact, I found one person who successfully got it working at this Reddit thread - and he even managed to get 2.0 to work with the addition of an XB3 gateway (which I refuse to do) - but nothing in his thread would suggest that he ever suffered from these interference issues.
This could very well be a dealbreaker: if I can't fix this, I'll try to move back down to the old RNG150 boxes while I still can. I would love to avoid that, though. So, please, if anybody has any ideas as to how to get the ECB6200s to play nice with X1, I'm all ears.

Moving to Chicago, which gateway does Comcast give you?
I am moving to Chicago in the next couple of weeks. I am looking at Comcast Xfinity and RCN. I see Comcast talks about 3 different gateways on their site https://www.xfinity.com/support/internet/about-the-wireless-gateway/.
I am considering either Blast 75, Extreme 150 or Extreme 300 and I am wondering which gateway you get with each one.
Also, can you rent a modem only? If so, which one? If you can't rent one, what is the most poplular one people get that supports up to Extreme 300?

[Speed] Massive error?
Comcast service was out for the better part of 11 hours today. When it came back up? Wow, okay. First, my modem bound the usual 12 ds channels, and 2 us channels. This is an Arris 6183 on a 650 mHz plant deployment in rainbow lake estates in central FL. But this is the test results when testing for ipV4:
http://speedtest.xfinity.com/results/J243Z5E9RUJIGC9
IpV6 tests are within norms, speeds provisioned as expected on a grandfathered Performance+ account capped @ 25dl/5ul.
Seriously? WTF?
Was I mis-provisioned or is this a glitch in the testing algorithm?
Thoughts, comments, jibes?

New Extreme 300 upgrade -- packet loss and low upload speeds
I'm not sure what I am really looking at here. I'm new to cable and just upgraded to Extreme 300 but I am seeing packet loss and low upload bandwidth and it doesn't seem to happen all of the time just more of an on off thing for the past week. I have already had a tech out and got a new modem, but I am not sure if this is a technical issue or just congestion on Comcast's end. I have another tech scheduled to come out and I am trying to learn as much as I can to make the most of his visit.
I do not know much about the signal levels but the tech said they were fine on the first vist: [att=1] [att=2]
I ran ping plotter for a bit when it was occuring around 12:30PM today: [att=4]
And here is a speed test: [att=3]
Does this look like a congestion issue or does it appear to be a line issue? Web browsing is okay when this is happening and download speeds are usually unaffected but also can be when the upload drops below 5Mb. Real time applications and gaming really suffer though. Uploads in progress can fail completely when this is happening as well.
Any suggestions on what I can try next with this?

Utah - Gigabit plan without OFDM? only 16 channels SC-QAM?
G'day All,
just got the HFC gigabit plan offered in Utah. It's great, though I'm not quite sure it's living up to the potential it has quite yet. :)
I have one of the new Xfinity XB6 (Arris TG3482G) modems. I see my speed tests tend to peak at around 350 to 400mbps down, and 41 or so upload.
I did a quick check on the channels bonded in the modem and it shows channels 1-8 as NotLocked, and channels 9-25 as the standard 6MHz SC-QAM channels.
So it appears I have a 16x4 connection for the gigabit plan.. I'm not seeing anything about OFDM channels available or connected, is there a way to check that on the XB6?
I wonder if it's just a boot config issue that might be happening?
Attached is a screenshot of the modem info.

[Rant] My Xfinity experience now includes being lied to at the store
For a couple of years, I've been paying $39.99 for 25/5 on two separate 12-month promotional plans. A year ago, the first of these expired and I walked into the store to see what was available. I think the first year was without a term agreement but that is not the main point, here. The sales rep said I could stay at $39.99 for another year with a 12-month commitment. Until now, my internet-only Comcast service has been reliable and justifiable, price-wise, just.
[att=1]
Yesterday, the second year had come to an end and I went to the store. Until yesterday, my experience at the store had always been satisfactory and I've recommended the store over phone or chat several times. I asked for my best deal and was told I could not stay with the same promo, any longer. I had to take a different promo with a 12-month commitment. This included a basic cable tv service with local channels, which I already get OTA, and HBO, which I've never watched when it was available to me.
I hemmed and hawed in my endearing jocular fashion but the rep told me there was nothing at my previous price--she explicitly referenced "$39"-- besides that and everything else would be more. There would be additional taxes and fees. I asked how much and she said about $5. So, about $45 for what has been good internet and some tv I didn't want with no better option. I resigned myself and signed on the dotted line. This morning, I received a cheery Xfinity email showing things are not what was represented to me:
[att=2]
At first, I considered eating the $110 ETF but then I saw there is a 30-day grace period to cancel without ETF. Later today, I plan to take the equipment back to the office, cancel, and get a receipt. I'll stay connected at the non-promo price until I arrange for a different provider, ASAP.

Message in Browser
I have been using a TM722g for the past few months. I know it is a 4x4 modem, and I am getting a consistent 140mbps. I am ok with the slower speeds, because it has been insanely reliable. I swapped out my third XB3, and their all in one gateways are junk. Now it sounds like they are sending me one, and I didn't even ask for it, nor do I want it. Has anyone else had this happen to them? I am on the Blast 200 plan if it matters.

[Moving] We may have to move soon
Quick question, if we have to move and we move to a multi family apartment building, is the install process and service availability pretty much the same as a duplex provided the building is cable ready (building already has Comcast cables inside and run to the individual apartments).
Moving due to sale of building.

[Signals] Signals looking iffy on the upstream side.
My up stream has always ran a little on the high side. During the Winter it would be 47- to 50 ish. Now I have 3 channels running at 54 and one running at 53. I also noticed today, that the TV was having issues with some of the channels. I know the line from the pole to the grounding block has been changed maybe 3 years ago. The line from the grounding block to the two way splitter on the other hand is about 15 to 20 years old I think. All the connectors seem to have stared rusting and such, so I think that line has gone bad. I will test it tommrow to be sure but I have a few question.
A) Should I use standard RG6 or quad shielded?
B) Are there special F connectors for out door use? As I found indoor/outdoor cabling at home depot.
C) Whats the best way to keep water from getting in to the connectors? Ive seen rubber boots. Are they worth it?
Any other recommendations would be nice.

[Signals] Do correctables/uncorrectables accumulate for ALL channel traffic?
Could someone confirm that DOCSIS 3.0 cable modems always tally up correctable & uncorrectable errors for *all* downstream traffic on a channel, whether or not the errored frames are addressed to itself, or to another user on the same node?
Some channels on my local Comcast system have become rather noisy lately, with errors coming in bursts. The modem may go an hour or so without accumulating any, then log several hundred in one minute, but I've seen little or no service impact while this was happening. Often as not the error bursts happen while my connection is nearly idle.
I suspect an ingress issue, since the worst-affected frequencies happen to coincide with local over-the-air TV. 555MHz = RF 28, WQXT-CD (virtual 22), and 591MHz = RF 34, WCWJ-DT Jacksonville (virtual 17), both of which are quite strong here.
Most of the plant is aerial, so maybe a loose fitting somewhere is shifting around when the wind blows?
All our HSI downstreams used to be in 609 - 747 MHz, at the top of the spectrum, and I'd go weeks sometimes without logging a single error, but a few months ago these were shifted down by about 100MHz, now spanning 519MHz to 657MHz , perhaps to make room for DOCSIS 3.1 OFDM above.
Now the remaining 600 MHz channels are still mostly clean, but 519-597 much less so, possibly from TV and other noise getting in. Last night power-cycled the modem several times, hoping to get back on the top of the band, but the CMTS wasn't having it... I guess it's trying to load-balance, and the lower carriers had fewer assigned users (might staying offline longer help? Do channel assignments commonly get cached for a while at the CMTS? Ours is a "CADANT" (now Arris?), according to its 00:01:5C MAC OUI).
With little service impact so far, unless it gets a lot worse this isn't worth calling in a trouble report on. I'm mostly just curious.

[Equip] Seeking best latency improvement - DOCSIS 3.1 modem or IQRouter?
I have 100Mbps service with Xfinity and am considering upgrading to a DOCSIS 3.1 cable modem or IQRouter home router. The reason being is I work from home and heavily depend on VoIP and VPN services having minimal latency. I currently have a Zoom 5341J modem and TP-Link TL-WDR3500 router. Due to the expense, I'm hoping to upgrade one device (versus both) that would have the most impact in reducing latency, specifically as it relates to Ethernet connections (wifi is not a primary concern). Currently, my ratings on dslreports speed test is -- Overall: B, BufferBloat: C, Quality: A.
Thoughts and feedback are appreciated, thanks.

[WiFi] Extra Hotspots with Comcast Supplied Modem-Router
I'm using a Comcast supplied Modem-router ARRIS TG1682G, Hardware revision 11.0.
I've disabled the Public Hotspot feature (at https://customer.xfinity.com/#/settings/security/hotspot ), yet I still see several separate hotspots coming from my modem-router when using a WiFi analyzer. I've confirmed they come from my modem-router because they disappear when I unplug it, and also because they share the same exact MAC address, minus the first two characters. This happens for both the 2.4GHz and 5GHz radios (which are both running at the same time servicing different clients).
2.4GHz: http://i.imgur.com/lF5a64F.png
The top hotspot beginning with f8: is the one clients actually connect to, with the other 3 mysteriously coming from my modem-router (as well as having different encryption options).
5GHz: http://i.imgur.com/ILjMG3w.png
Same as with the 2.4GHz radio, clients connect to the hotspot beginning with f8:. There's 1 less "extra" hotspot than the 2.4GHz radio, and the other hotspots again have different encryption options.
Everything looks normal in the modem-router's settings (Gateway > Connection > Wi-Fi). It only shows the 2 hotspots that I connect to, the 2.4GHz and 5GHz, both MAC addresses beginning with f8:, as you would expect.
What are these extra hotspots? No other router I've used has had them before, but I haven't been able to find other people complaining about this, which leads me to believe it's probably normal. What function do they serve? Are they causing any interference with the hotspots I'm connected to?
