This morning, I lost IPV6 on my own Arris SB 6183 modem/ openwrt router setup. Recorded message said that they have done some upgrades and to restart the modem. I did that, still no IPV6 and my IPV4 is also in a different subnet. So I called them. The tech. says you have your own modem, so I cannot help you. Nothing has changed on my side. What are my options? Does Comcast want everybody to pay rent for their modems? They are able to remotely reboot my modem, download boot file. (They killed my old modem by downloading a wrong file in the past) Yet they say they cannot help me?
I moved away from AT&T/Sonic because they forced their modem/router combo, it seems that Comcast is doing the same.

gig finally available
So, i received an email with a subject line that said 'Slide into fast Wi-Fi speeds' last night.
Nearly every time i pay my bill, i browse the change plan page just to watch its changes. in 3 years of living here, 200/10, followed by 300/10 has been the fastest offering.
Logged in just a few moments ago, and all the tiers up to 1200 are now available. The system successfully let me place the order for upgrade desiring my own equipment, self install, and i took a second Flex box as they offered it free.
On my way to the store to snag a D3.1 modem now. Ill report back later with how activation goes.

[Signals] Downstream Signal Issues
Just decided to check my XB7 modem signal levels
and results are the pictures included below
Upstream all locked
Speedtest shows normal thus far

Splitters, Moca, and the Cable Modem that needs to cooperate
I have a bit of an issue where I would like to keep using my MOCA 2.5 adapters with my Arris S33 cable modem, but with the way I have things set up, it requires me to double split to the cable modem where my "data room" is. This double split I describe is as follows:
The xfinity box outside - A 2 port Antronics splitter - one port goes to data room, one goes to living room.
Data room - would have the 2nd 2-port Antronics splitter for cable modem and Moca adapter. I have the Screenbeam/Actiontec 7250 that's has the 2.5gbps port. 7.0db loss
Living room - will have the 2nd MOCA adapter and nothing else, no additional splitter 3.5db loss
The problem: Upstream signal levels on S33 hit 50-53 when I'm double split as described above, and disconnections/packet drops occur. Without any splits, direct connection from modem to box, my upstream is in spec anywhere from 42-46, and everything is pretty much perfect.
Will Comcast tell me to pound sand or should they have to improve my signal levels to handle 7.0db of split to a cable modem? Especially since I have no interest in getting TV service and I'm fairly positive they won't give a crap about my moca setup.
I ordered Amphenol Broadband splitters that allow 5-1675mhz, one unbalanced 3 port and 2 balanced 2 port splitters to nail down what is best, as I would like to expand MOCA to a 3rd room in the future, and i want to be able to utilize Extended band D/Moca 2.5. But I've established a base case of "I'm screwed" with the 5-1002mhz splitters i was provided by Comcast unless they do something to make my upstream levels without splits in the high 30s/with split mid 40s to cable modem. Will they just shrug and say "it's fine" or will they do anything?

Comcast & ACP
I have been a cable subscriber since the late 90's when @home was first cable available. I joined this forum and learned how to optimize my connection and cajole customer service for deals. Later I owned a home and even started installing networks as part of my business. So being reliant on a program fully funded by the fed and getting treated like a second class customer makes me bristle. At least they have knowledgeable phone techs now. In fact, a conversion with one tech I called after I found out that EBB customers were excluded from using the wider wifi hotspots thus not being able to use VOIP and his description of how differently the plan has been rolled out in his state. It got my guard up for how the transition would go. Sure enough it was rocky and I did get a charge! $12.26 for a pro-rated amount of days of service. I did get that reversed though.
As I posted I didn't learn about how to get EDD until Oct last year and went most of lockdown without service. I turned in my modem May 2020 as I lost my job in April. Like many Californians I still have not had my unemployment processed and my income is nil. So when I heard about the EBB and called and asked they acted ignorant. And then when I did get it and had a question I stopped in store where I got the router and customer service wouldn't help me at all. Because I was EBB. This floored me. I was making plenty of money so I didn't worry back then but comcast bills got out of hand and service reps were abysmal. I have paid way too much money and spent hours trying to get services to be treated poorly. More importantly it shouldn't be shameful to use an essential utility ever. The only way to do anything important including doctor's visits is online now. Access shouldn't have so many hurdles, fees and tiered controls. I know it is not just comcast but online the consumer is the product and they want YOU. Having any privacy and hopefully some security takes time. But now more than ever it would be nice if this company were less awful and understood its role not as a defunct monopoly raking in as many superfluous feed as possible but helping people connect to jobs, medial treatments and family support. Those things build a society and instead were are getting less options, more ads now too. I filed a complaint to the FCC and got a call from their uber elevated support. It was an interesting call but Comcast/NBC needs to be called out for their unnecessarily vague and difficult attitude in rolling the ACP.
Service was out here for 12 hours last night and a bunch of new stuff was changed/added. Sorry if I am a squeaky wheel but as someone who may be going back to work in rural network infrastructure and who grew up in a place where they still use telephone wire service I see data in the 21st century as essential as water or electricity. For many seniors it is. Lower income customers should not be bitch slapped with fees and Comcast's stance is still terrible. Just curious what other people's experience might be might be like.
On a more positive note service is very consistent and plenty fast. I don't like how you can't configure your own modem anymore I hope they let me use my own so I can forward ports. They have a UI that supposedly allows the full Arris modem menu but it doesn't work via Edge or Firefox and since the internet came up last night all sorts of different certificates and privacy statements have updated. I know many people don't have time to worry about privacy or keep tabs on latest changes but Comcast and its parent company are not only getting fully compensated for this program but they are also harvesting an ungodly about of customer data which is very profitable.
We, as consumers, are the last line of defense and I think Comcast can be a better corporate citizen. I encourage anyone who feels chagrined to share your experience with the FCC. You will get a call back from Comcast support who will trot out the party line. But I was able to be heard and expressed the particular grievances. He agreed they could have done better. Hopefully I won't have to be so financially strained but many are now. Corporations have been flooded with stimulus money and special programs it would be nice to see a rising tide float all boats.
Cheers.

Overbuilding
Comcast is pulling fiber along major streets here in Bradenton, FL. I don't know if it is a full overbuild of Spectrum or a partial overbuild. Spectrum is the primary cable co in Tampa Bay. Comcast covers Sarasota and most of the Lakewood Ranch section of Bradenton. This overbuild is all underground and all fiber. I have no idea if they are targeting business customers only or residential as well. They have done a similar overbuild in CT in the areas are served by Breezeline -Formally Atlantic Broadband in New London County. I grew up in Ledyard, CT which is in New London County. I wonder why Comcast would overbuild Spectrum?

Did I just trial LLD??
Am having ping spikes and packet loss due to congestion on the node/cmts, reached out and eventually they started messing around with the cmts/node side of things. Saw them go from 5 upstream channels to 6 back down to 4 before the actual node split happens may 26th. Last night later in the night for a few hours I noticed something interesting on pingplotter. Its like they turned something on for a few hours and then off again. Second screenshot is when I notice a difference in service flow. Last screenshot is how my morning/noon/afternoon/nights usually go depending on utilization. Im trying to reach out to the team to see if they cant keep me on the service flow or give feedback and thought I'd post here to see what ya'll think about this

Northeast speed increase finally happened?
I'm in a newly-built extension of the Williamsport PA market, and today I see that my download speed has gone up by 50% and my upload speed has doubled. I see nobody talking about this on any forum, I haven't seen any announcement from Comcast, and my account still lists the old download speed.
I looked at my modem stats and I see that it rebooted 3 hours ago (though this may be due to them cutting in a new tap for some customers up the road from me, I saw them working on it on the way home, that's why I checked everything when I got home.) I have 31, 256QAM channels and an OFDM channel for download, and 4 QAM channels for upload -- although I can't remember how many it used to be.

Trouble Accessing Certain Websites
About two days ago my wife had some issues accessing certain websites. I blew it off to a Cache/Cookie issue. I rebooted the router to be safe. Last night she showed me it still was not working.
The website will not come up on Wired or Wi-Fi on any device. If I use my ExpressVPN they work. They also work on the phones with Cellular Data. I have checked everything I can think of and also swapped out my modem (didn’t realize it was outdated).
Tech Support was no help as you can imagine.
This is the message I receive
Access Denied

Speeds
Well I pulled the plug and dropped the Tv portion of the bill. Went with unlimited Data because of the streaming and my Son downloading files/programs for his Xbox or Play Station. I was getting some bad speeds at first. Finally figure it out. My netgear router had QoS turn on. With that off I get 946Mbps down and 23.98Mbps up.

Best 3rd party modem in 2022?
I haven't looked at modem in a long time now. For gig service without phone what modem is now the best? Are there chipsets that are giving problems?
↧
downgraded to only 3US
Overnight my service was reduced from 4US to 3US. There were a bunch of errors in the logs around 3AM. Rebooted my modem and still only have 3US. Missing the lowest channel; the one that's around 17Mhz.
Levels look good. Downstream about 5.0dBmV across the board with 42dB SNR. OFDM a little hotter at 6.0dBmV. Upstream is at 44dBmV. Never have seen any indication of signal problems before.
Here I was hoping I'd get a 5 or 6 US.... NOPE, downgraded to 3. Not the right direction.

[Connectivity] High amount of upstream packet loss
Hey everyone,
I have been having issues off and on with packet loss from my pfsense router, thru my MB8611 outbound. Stats looked fine, but I rebooted the modem - took a loooong time to sync, but came out. xfinity tool came telling me the modem is not connected/is connected. Contacted support and after spending time explaining the issue is not with my wireless signal or a specific computer, he finally ran a diagnostic and "something failed". Modem stats (that I can see) look fine, but I am sure it's something either on the other side or my 3 month old modem is having problems. I am not sure how the stats look so fine in one direction could lead to a issue with connection. After making the appointment (tomorrow), it looks like it's starting to right itself.

[Signals] 6 Upload Channels?
All up here in southern NH, I noticed that we went from 4 to 5 upstream channels this week. It shows I am bonded to 5. Where it shows the channel starting at #2 does this mean we have 6 upload channels now?

[Signals] help with signal levels and splitter recommendation..
these are my current levels, i noticed there is a power amp installed ( a ppc 5 port one ) for whatever reason im unsure of. but i want to know, if i get an atronix 3 port splitter which one to get. 2 tvs and one modem. also will getting an atronix one make current signals worse or still be ok, have some intermittent ping spikes at times, so its why im posting and asking.

Major CyberAttack
If one does happen which I hope it doesn't what will Xfinity do about getting people back online? I've heard rumors that Russia will do that and Klaus Schwab has even said it himself
Do you think it will happen or won't happen?

Next Gateway XB8 - Technicolor CGM4981COM Wi-Fi 6E
Looks like we have a new DOCSIS gateway by Technicolor on the horizon. A new listing went up today mentioning a "CGM4981COM." Not much info about it as the documents are early, but the testing reports that it is tri-band with Wi-Fi 6E.
This device has 4x4 AX on both 2.4 and 5 GHz like the current XB7, except with 4 more separate antennas for Wi-Fi 6E support.
https://fccid.io/G954981X
This gateway hasn't been tested for DFS support yet. Not sure why, but I also see it hasn't been really tested for 6 GHz either, like another ISP device that apparently is Wi-Fi 6E.
The label on the bottom is oddly shaped, so I would expect the device to be a little strange as well.

I’m wondering if anyone has a time frame of when this will be implemented. I’m assuming either later this year maybe hearing an announcement at the expo this week or sometime early next year.
