[Speed] Extreme Pro 400 Mbps nightmare
What a nightmare. I added Extreme Pro to my account and of course when the boot file was sent to my modem it defaults to Performance. Call tech support and get transferred to Enterprise support. Fucking idiots. I am calling back in again... seems Comcast doesn't like my SB6183???

[Plan] Provisioned speed of "Performance Plus"?
With their latest price increase, it appears that Comcast would like me to downgrade my service once again.
They list a "Performance Plus" tier of service in my area. I don't even pretend to follow their constantly changing naming conventions any more. This one lists a speed of "up to 55 Mpbs" blah blah blah. What are the actual provisioned up and down speeds?

To get the increased speeds, most customers will simply need to re-start their modems when notified by Comcast that the new speed is available. Comcast will also notify customers who may need to upgrade their modems to receive the increased speeds. Customers who lease modems from Comcast will be able to receive upgraded modems at no additional charge. Customers who own their own modems and need to upgrade their modems to receive the increased speeds will need to purchase a new modem or can lease a new modem from Comcast. ...EDIT: Karl also has a news item up on this now: https://www.dslreports.com/shownews/Comcast-Begins-Bumping-Performance-Tier-From-50-to-70-Mbps-139061

[Signals] Signal check please
I have a TG1682G modem. I am concerned because one of my upstream channels is "missing".
I have 24 downstream channels all locked.
My downstream SNR ranges from a high of 40.95dB to a low of 38.61dB
My downstream power level ranges from a high of 3.40dBmV to a low of -0.80dBmV
All 24 channels show 256 QAM modulation.
I have 4 upstream channels.
3 out of the 4 are locked.
3 channels have a symbol rate of 5120KSym/s
The power levels for the three locked channels are: 47.00dBmV, 47.75dBmV and 46.50dBmV
The 3 locked channels have 64QAM modulation.
The channel type for the 3 locked channels is DOCSIS2.0 (ATDMA).
The upstream channel not locked is 17.30MHz has a power level of 0.0dBmV and shows QPSK modulation.
Performance seems fine, speeds are great: 195Mbps down and 12Mbps up with 16ms latency.
Suggestions?

[Firmware] cm820a
In late spring of 2015, I followed Comcast's suggestion and bought an ARRIS DOCSIS 3.0 Touchstone WideBand Cable Modem model CM820A version 1. Soon after I plugged it in and got it authorized, Comcast updated the firmware to TS090193_061815_WBM760_CM820 Firmware Build Time: Thu Jun 18 05:09:46 EDT 2015. The update removed the option to use Arris Password of the day to access "Advanced" tab data thought the modem's built in web page, but other than that didn't seem to do anything. Occasionally I've found I've need to unplug both the modem and my home network router in order to get internet access back after Comcast internet problems.
Today our home lost Comcast internet connectivity and I first thought it was just another of the frequent outages when the weather changes, but when I hound that there was no outage, I just cycled the power on both the modem and the router. When that didn't work, I checked the modem's built in web page, and found that Comcast had updated the firmware to TS0901103M2Y_071817_WBM760_CM820 Firmware Build Time: Tue Jul 18 08:17:57 EDT 2017.
I then found that when to connect to web pages with Firefox, a bar appeared on top of the window saying I need to authorize my my "new" modem using my Comcast account logon. I tried it but the process just looped around with no end so I called Comcast.
The technician I reached insisted that Comcast NEVER updates firmware in customer owned cable modems, and suggested I contact the manufacturer. I insisted that I've not only seen Comcast update customer owned cable modem's, I've read on many sites that its common practice, including on the Arris website. After saying I would call back and hopefully reach someone who might understand about Comcast updating customer modem firmware, I tried unplugging the cable modem, pressing and holding the reset button, and then while still pressing the reset button plugged the cable modem back in again. Our internet access was instantly restored without requiring anything else.

[Signals] Lost one of 4 upstream carriers following maintenance outage
Last night my Comcast service was out for about 8 minutes, starting at almost exactly 1:00am, so I suspect that was scheduled maintenance. Unlike with some past maintenance events, the modem lost all its signals at the RF level for the duration.
When it came back, all looked good except that one of the four upstream carriers, the one at the lowest frequency (16.6MHz) was gone. We've only had four for less than a year. I power-cycled the modem one more time, about an hour later to make sure it hadn't just failed to lock on the first time around.
Could this lowest upstream carrier have perhaps been converted to DOCSIS 3.1 OFDM modulation? Would doing so have netted a significant capacity increase for customers with 3.1-capable modems? I assume those are capable of bonding to both to both 3.1 and 3.0 upstreams at the same time and splitting their traffic across them as directed by the CMTS?
Maybe the OFDM carriers can be extended a little further down into the high-noise "swamp" spectrum below 12MHz? Being able to set individual subcarriers for fewer bits/Hz as noise levels increase must help.
If OFDM is being used now in the upstream, I wonder how they're dealing with that modulation's notoriously high peak-to-average-power ratio, with regard to laser-clipping concerns. I guess the cable modems just aren't allowed to transmit with as much power in this mode?

Comcast downgraded our area recently from 32 channels to 28. I was able to confirm this was NOT for D3.1. I wanted to know if the same has happened to any other areas. I am a little worried they could decide to cut it some more. I don't expect D3.1 in more area to after 2020.

[Speed] Seattle, WA DOCSIS3.1 Gigabit MB8600 Suddenly Slow?
New to the site, hopefully my post is OK. I've had the MB8600 for a while, I was on the Extreme300 package for a year or so and had no issues getting 300Mbps download. I recently upgraded to the Gigabit service when it became available in Seattle. Took me calling about 5 times after I initially upgraded via the sales department for them actually to send the correct gigabit config file to the modem (see above).
Anyway, the speed was fine, in the 700-900Mbps range for the first week or so, but for the last 4 days it has slowed dramatically to less than 100Mbps. Not sure why this would be? I tried calling tech support but they were absolutely no help. I posted signal levels below. The # of downstream channels doesn't look any different to me then when I was getting full speeds on the service, but maybe I'm missing something as I'm not an expert at this stuff.
Anything jump out to anyone from the images below as to why I'd be getting such slow speeds? Is it possible that they've been doing work on the network for the last few days and that's why? Tech support didn't offer any insight.
Modem is connected directly to my mac via Cat6 cable at the moment.
Thanks!

[Equip] Recommendations for a replacement modem/voice?
I have Internet, TV, and Voice service right now from Comcast, so unfortuantely my options for a modem are a bit more limited since I have voice service. Right now I have a Cisco DPC3941T... and I hate it.
First of all, I am not happy that it's also a router and wifi gateway, I have my own, and really don't like having this extra mess that I have little control over. The rep who gave it to me said that they had no plain modem/voice devices anymore. Furthermore, it seems to be ignoring my settings now.
As I said, I have my own router, so I have no need for the modem's built-in features. I went in and disabled all the WiFi hardware, went into my account and disabled the hotspot service, and even set the modem into bridge mode. This USED to work.... but not anymore. Now, the WiFi lights stay on and blinking even though it claims the WiFi is "off". I looked this up, and apparently the official answer is that this is a "bug" in the firmware and that they really are off... but that appears to be a lie, since it's now causing interferance with nearby audio equiptment when it didn't before. The interferance goes away if I move it further away or unplug it, and it used to be right next to the equiptment without causing interference before, back when the WiFi lights actually stayed off. Furthermore, some people have reported that it beroadcasts hidden 2.4ghz channels anyway.... and now, it's not even bothering to lie to me about it, it's even saying in it's status that the 2.4ghz band is active, even though I turned it off.
At the time, the tech who forced me to replace my own voice/modem with this gateway said I had no option but to rent from them due to the voice service, claiming that due to 911 restrictions I can't buy my own, I don't know if he was lying or not, but I recently noticed that Comast has an official page that lists "compatible" devices you can use iof you were to buy your own.
So, that's what I want to do. I am also guessing that Cisco DPC3941T they gave me is likely the lowest in terms of quality as well?
These are the ones Comcast claims would be "compatible" with my service:
https://i.imgur.com/bsCiHIA.jpg
Can anyone give me any recommendations on which ones to get? I know that obivously Comcast will still have some control as they will have to push their configuration to it for my service, but will they still be able to override my WiFi settings and force it on like they are doing now? Are any of these which do NOT offer router/WiFi features (what I would prefer) any good or better than my current modem?

[Connectivity] Daily short connection failures.
Hello
I live in Media PA, a suburb of Philadelphia. My internet setup features a Comcast Xfinity modem in the basement, which runs up two floors to a Netgear N750 router in the office, which serves as the main wi-fi source, along with wired connections to the desktop in the office, as well as to my gaming PC in my bedroom. In terms of anti-virus, I run Windows Firewall on my gaming PC, as well as Malwarebytes as an anti-virus.
With all of the components mentioned, the issue I've been having involves my internet connection (on wired devices and wireless alike) going down for a brief period of time (often not even a minute). It comes back after a while with no obvious drop in speed, but the moment when the connection goes down is enough to completely mess up things (as a gamer, I find this incredibly frustrating). When it does happen, I run a diagnostic to see what the problem it, and it is often presented to me as a DNS Server issue. This indicates to me that it's likely not my router that is the issue (though feel free to correct me if I am wrong on that one), and that it is something with the connection itself or something with the DNS server or something of that nature. This issue has been happening for well over a month at this point, and it seems to happen daily, often in the evening, though I have caught it happening in the early afternoons and in the mornings as well. If there is anything out there that can resolve this issue, that would be greatly appreciated.

The XI Gigabit DOCSIS 3.1 is now available in my area. I am tempted to sign up. Early reports said unlimited data with a 3-year agreement. The Comcast website says nothing but the typical disclaimer about the data usage plan. I don't want to sign a 3-year agreement for a plan with a data cap. Does anyone know if the XI Gigabit service is subject to the data usage nonsense?

[Connectivity] Bufferbloat spikes during upload testing. T3 Timeout's
Hey guys, Been experiencing some slightly strange issues with my Xfinity internet recently.
I'm in Bellevue Washington and I was using an Arris SB6183 Modem, now I am using a Xfinity supplied standard gateway w/ bridge mode turned on for my ASUS RT-AC66U.
Basically, few weeks ago, friends started telling me my voice sounded laggy or robotic at times when I spoke in online voice chat.
This would be random, no real observed pattern, only happens for a few seconds to a few minutes at a time.
Noticed strangely that my speeds were all fine, and that I could hear others perfectly fine. I was usually in game as well, and I did not experience a lag spike.
Was able to finally catch on two separate occasions some bufferbloat spikes on upload testing.
Fast forward a week. One day the internet on my modem goes out. Lights everywhere are still fine. Reboot the router, get no internet connection, says I need to contact ISP for DHCP error.
I reboot the modem and the internet is restored.
The next week I started experiencing slightly more frequent lag spikes, now my lag spikes are much more measurable, was also getting packet loss as well.
Then the speed one day just dropped off to crap. Terrible speeds.
Comcast techs were able to come out and identify a large amount of line noise, they said there was a lot of line noise in the "Upload SNR"?
Line maintenance came out and replaced the line going from my house to the main telephone pole. Still had issues, had the rest of my wires replaced yesterday.
Still the same issue on that modem.
Swap out to a Comcast modem and the speeds went back to what I was supposed to have before.
HOWEVER. I'm noticing... slight delay or a slight delay in loading of web pages. Seems slower than before. Been testing all my speeds and what not, speeds are fine.
However, I've been noticing some bufferbloat spikes, especially on upload. (I remember I've had this problem since I got my service I believe).
I turned on my QoS like usual, limited it slightly and it made the bufferbloat slightly better. However whenever I do the test, right at the start of the upload test there will be a HUGE spike in bufferbloat (which immediately goes down).
I've been monitoring my Comcast Modem logs and its shown 3 of these errors: [Docsis][969]: No Ranging Response received - T3 time-out
(I've had this Comcast modem since yesterday at 3, its been around 27 hours.
I still have the logs saved for my Arris SB6183, and my Arris had quite a few T-3 Timeouts and No ranging response received errors as well.
What do you guys think the problem is? It still seems like there could possibly be something wrong with my upstream... however my modem stats look fine. Its just the logs showing errors.
I've had comcast techs look at my power levels and what not, they were all normal/ good (Arris).
I've done some research and it seems like im definitely not alone with this issue, especially on some Arris Modems.
Do you guys think its my modem that could possibly be faulty? Or some kind of issue on Comcast's end? or both?
Here's some of the logs I've gotten from my old Arris Modem:
These are most of the ones I've seen. The Timing Sync Failure is spammed completely all across the logs. Most of the logs are those.
And there were quite a lot of T4 timeouts on the 23rd.

[Equip] Actiontec ECB6200 bonded MoCA bridges with X1 boxes - help!
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.

[Equip] Modem with 5 - 1002 MHz spectrum analyzer
So I'm not sure if diplex filters on modems would prevent it seeing any upstreams it's not locked to, however do you guys know of any modem that'll do a full band capture in the 5-1002 MHz range?
I think I should be able to capture upstream bursts from other modems on the node too, though obviously only those either on the same line extender or further down the line.
Don't care whether it can actually tune to 8 channels or 32 + OFDM, don't care whether it supports 6 MHz or 8 MHz QAMs, purely for use as a ghetto spectrum analyzer, and it must capture from 5 MHz rather than just the 3.0 downstream from 108 MHZ onwards.
Thanks all :)
