[Signals] Are these signal strengths okay? Modem had a 6db attenuator..
I think I got the MAC address etc. out - this is from Comcast on a Arris sb6121. Does the attenuator the installer left need to be reconnected or do we have decent signal strength for trouble-free operation?
Thanks

[Speed] Side Discussion About Gigabit Pro & earlier Gigabit Deployments
Anyone know if Comcast has actually started installs? I live in the west palm beach, fl market announced for deployment this month. So far phone agents don't know anything of the service. I've been told by different agents, 2016, June and it'll be in the system tomorrow. None had even heard of the service before I inquired and they did a bit of research, so I went to out local sales office to inquire in person. There I had to show them the press release, to which they simply said its not yet available in the market. Seems like this was a pure fiber to the press release hail marry announcement to try to salvage the dead merger.

[Connectivity] Xfinity Signal Help
I'm a bit of a newbie but am having some issues after installing a new NetGear 1900ac 7100v (24x8) modem/router.
Most of the time things are fine but streaming anything over the TV (Amazon, Netflix) leads to drops and crashes. This didn't happen when I had an older, slower modem/router.
The signals I'm getting are poor I think but I'd like someone with a bit more expertise to take a peek so I can get the tech (who's coming tomorrow for the second time) to understand exactly what's going on.

[Equip] Should I get a CM600 or TC7650-E to replace a Motorola 7420?
Recently stepped up from a ultra reliable 8x4 Zoom 5345 to the 16x4 Motorola 7420. I've had it for a week or so and it is proving to be just as reliable compared to the Surfboard 6141 I've owned before.
I never knew much about downstream channels until I did some Googling and courtesy of this site I see that 24 downstream channels are available in my area. When I look at my Motorola's GUI interface I see that channels 9-24 are bonded iirc.
Couple of questions...should I step up to a 24x8 modem to take advantage of the extra 8 channels? Right now my speeds with Blast are about 233 down and 12 up. Will those extra downstream channels make a noticeable difference? I imagine not in speed but maybe extra pipes help in congestion?
Thanks in advance for any advice if it is worth it to make the change to a 24x8 modem

Just received a letter saying that my docsis 2 modem will die
Just received a letter from Xfinity informing me that the modem I own, Arris Motorola SB5120, will suffer significantly reduced speed on August 10th and will eventually lose all internet service by August 30th.
Thing is my internet plan goes up to 25 mbps and my modem supports up to 25mbps, why would it die? Is my modem really going to die within a month and I'd be forced to buy or rent a modem when I intend to stay on the 25mbps service?

[Connectivity] Arris SB8200 Activation Issues (Cisco CMTS)
I just got my new Arris SB8200 from Amazon yesterday. I am having a problem where it just keeps cycling through the downstream, upstream and internet LED indicator lights. I called Comcast twice they both said they don't even see the cable modem connecting to the system. Both times they insisted there was something wrong with the CM and to return it. So I'm doing that just to prove them wrong. I tried a number of things including not plugging in the Ethernet and power cycling the modem manually many times and let it sit for about a hour and a half cycling through. The modem is supported in our area on the Comcast device support page.
I was told in this thread (I am the Anonymous user) (http://www.dslreports.com/forum/r31304106-~time=1489503828?r=151#31304106) that it may be a problem with Cisco CMTS units (much like the Netgear D3.1 CM issues with the CM1000's). I Verified and the CMTS Mac address is indeed Cisco owned. Though I'm not sure what model I am on. There was a mention that someone named "netcool" on these forums has a fix (http://www.dslreports.com/forum/r31303566- & http://www.dslreports.com/forum/r31303256-) (I'll try PMing netcool also). Is there anyway that can be applied in our area also? Or is there a way I can call Comcast and not get level 1 support that can fix this issue?
UPDATE: My issue was resolved by the workaround the user "netcool" applied to my area's CMTS. Latest info is there are plans for a more permanent fix in the works.

[Speed] Comcast Speed Test Low Results?
Comcast speed test has always returned low latency values and high download speeds (ie 15 ms, 229 Mbps).
For the past week or so it's been 60 ms and 60 Mbps.
By comparison all other speed test sites including dsl reports speed test results are low ping and high download speed.
Are there issues with Comcast in Foxboro, MA?

[Plan] Side Discussion on DOCSIS 3.1 Gigabit service
Mod Note: This topic started as "XI Gigabit DOCSIS 3.1 - data cap with 3-year agreement?" It has become a general discussion of this deployment, hence the title change. uid://455626
If you actually have had this service installed, the stickied report topic is here. > https://www.dslreports.com/forum/r30960001-Speed-Report-DOCSIS-3-1-Gigabit-Service-Here If you report, please include info requested in the first post and keep that topic strictly on topic. Thanks, sortofageek
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?

[Signals] Packet Loss - Signals look fine & Arris SurfBoard SB8200 modem
Exactly 3 weeks ago on June 8, 2017, I replaced my Arris SB6190 DOCSIS 3.0 modem with the Arris DOCSIS 3.1 SB8200 modem, I have been having timeouts browsing the internet as many connections will timeout and require that I reload before it will work properly including posting here where I hit the Post Now! button, it just will say waiting for connection in the browser for 1+ minute until I hit Post Now! again before it will post. Even with speedtests, I was getting 50Mbps down/11Mbps up most of the time and about 5% of the time, it will be somewhere in the 140Mbps down/11Mbps up range. This is on a BlastPro 200Mbps/10Mbps connection here in Comcast San Francisco, California. I have already resetted the modem to factory defaults and have tried directly connected via Gigabit Ethernet using CAT6 cable to a computer with the same results. I had confirmed with netcool within 2 hours on the same day I began using the modem and he said it was provisioned correctly and the signal levels look good. The SB6190 did not have the same issues but the speedtests were 80% in the 180Mbps down/11Mbps range but that was when it was running on 24 channels down/4 channels up. Now it's 32 channels down/4 channels up and 1 DOCSIS 3.1 down channel. And we all know the SB6190 has other known issues that the SB8200 does not have. Even on this side, as I have posted status pages before, the signal all looks good even though it reports a T3 timeout about once every 2 days per the error logs.
So on June 15, 2017 - I wrote on the Comcast Direct part of the Comcast/XFinity forums here on DSLReports.com describing the problem and the response was:
"Hello {first name} looking at the signal on your modem I confirmed there is a high amount of resets and highT3 timeouts count which can be related to a RF problem can you please confirm connections from the back of the modem as far back as you can. Thank you"
All the connections look fine to me as there is the underground cable from the underground tap which is in the private street in the back of the house to the grounding block at the back right corner of the house and then cable from the grounding block going up the roof and then down to the left front outside wall of my living room going into the coupler and then the cable directly to the modem. The coupler and cable directly to the modem was professionally installed by a Comcast Business Internet contractor in February 2016 before I switched to Comcast Residential High Speed Internet. Everything before the coupler back to the tap is atleast 10 years old if not longer.
I wrote back and basically the Comcast representative did not respond until 4 days ago saying there has been a huge increase in T3 timeouts and they like to send a technician to check the signal which was scheduled for yesterday at 1PM-3PM.
The technician arrived yesterday near the end of the appointment time window at 2:50PM and first checked the signal from the modem which looked good but was on the telephone with his manager who said there were 100s of resets during the past 3 days while it only shows 2 in my error log so they checked the signal again at the outside of the living room wall and then at the grounding block where the underground cable from the underground tap comes in and they all look good and then we went to the underground tap which feeds 3 houses, mines and my neighbors and basically, instead of the wires deep, it was all on top of the solid dirt and it appears one of the ports on the tap is broken so what was done was the following:
The cable from the grounding block in the rear right corner of the house going up the roof and down the left front outside wall of the house was replaced with a new one and the old one was removed while the coupler was also replaced. I do not have a photo of what it looked like on the grounding block side before the cable was replaced. He had a fellow co-worker came over who agreed that the broken port on the tap could cause ingress even though the signal looks fine. So what is being done is that Comcast Construction will fix the tap as soon as today while they will run a new underground cable from the tap to the grounding block, the later which will take about 7 business days. Now a question, is there a such thing as a defective grounding block since I thought if it is old, it might not pass all the frequencies.

Windows Auto tuning Question?
Hi everybody! Got a Question for those in the know. I got Comcast new 1 gigabyte down and 35 megabits per second up. I am trying to get buffer bloat as low as possible. I have been messing around in Windows 10 Netsh or Net Shell commands. When i do a speed test without messing around in the windows auto tuning command at www.speedtest.com i get roughly 980 to 940 mbps down and 40 to 42 mbps up. When i go into www.dslreports.com i get the same but get an F on bufferbloat on www.dslreports.com
Here is the weird thing. When i turn windows auto tuning to disabled instead of normal this is what i get. On www.speedtest.com i get 980 to 940 mbps down and 40 to 42 mbps up, but when i goto www.dslreports.com i get 399 to 410 mbps and 40 to 42 up and i get and A+ on buffer bloat test. If i reset winoows auto tuning back to normal instead of disabled on www.dslreports.com i get my speed back at 980 to 940 mbps down and 40 to 42 up but get and F on bluffer bloat. My question is why does my speed diminish to 400 mbps down on www.dslrports.com but on www.speedtest.com show 980 to 940 down?
I do not have qos settings turned on in my router just default settings.
Just wondering if anyone can enlighten me on why my speed on dslreports drops the speed to 400 mbps down with windows 10 netsh int tcp set global autotuninglevel=disabled but www.speedtest.com speed shows 980 to 940 down?
Help:-)

[IPv6] Comcast apparently not using IPv6 for modems in all areas?
Noticed the above recently at a site we installed (apologies for the graphic, but I only have CLI VPN access to the site at the moment). The IPv6 address is a link-local (fe80::)... apparently they don't have IPv6 rolled out for the modems in this area? The site is part of a "bulk agreement" of many different homes, but is still just regular residential service.. Modem is Zoom 5345

[Plan] Any Comcast Internet Essentials customers here?
I know that if you are, you might not want to admit it. Anyways, I have the service, and while it's mostly pretty stable, and I think not subject to a usage cap, it is slow. 12Mbit/sec down, 1Mbit/sec up.
Downloading a bunch of Linux ISOs, takes 2-3 hours for a group of them.
It was slow enough, that instead of cancelling my FIOS 50/50 plan, I boosted it to 75/75. (I have both.)
I am using an Asus AC68R router, flashed with Shibby Tomato firmware 140-MultiWAN. I use(d) the multi-Wan feature, to do weighted round-robin load-balancing between the connections, although now that I've boosted my speed on my FIOS connection, I may just use the Comcast connection for fail-over.

[Equip] MB8600 Slow Speeds
Just replaced my old SB6120 with a MB8600 and am getting much slower speeds. Running Ookla speed test was only giving me between 30-60Mbps (tried each port). I'm on the Blast Pro 200 tier (Redmond, WA), so the number should be around 200Mbps.
The MB8600 lists the configuration file as: d11_m_mb8600_blastpro_c01.cm. I'm guessing this is the right one, although I don't know for sure.
The SB6120 was able to get 130Mbps.
An Xfinity tech came out the other day, did some tweaks to the cable lines, which didn't improve anything. He suggested we try an Xfinity cable modem, the DPC3941T instead, which oddly enough was able to get around 200Mbps.
I recently tried several other modems (Arris SB8200, Arris SB6183 & Netgear CM400), all with very similar results (30-60Mbps).
Anybody have any ideas on what could be going on?

[Equip] YA SB6121 Blast 150 Thread
I have an old SB6121 that I would like to use even if it bottlenecks my performance. I have ordered 150mbps blast service.
Is comcast still activating these modems for this service? Is it correct that the maximum speed to be expected would be about 120-130mbps? I am fine with that if that is the case, but I just want to make sure. Thank you
