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?

[NEWS] Comcast line tech: Speed increases coming March 1
https://www.reddit.com/r/Comcast/comments/su328q/speed_increases/
Comcast line tech said he has heard from co-workers in multiple regions that speed increases (including upload) are coming March 1st.
He says in the comments that the NE region is getting the new tiers that the other regions got last year.

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.

Pick a Date - When to Cancel
Ok, silly question, but now that Comcast does not refund for mid-period cancellation, which date is crucial? For example, my billing date is the 6th for coverage from the next 16th to the following 15th with autopayment scheduled for the 27th. My guess is if the service is cut off by the 16th, the final bill, already generated on the 6th, can be ignored. But is that how Comcast plays it?
New service has been established. Trying to avoid any surprises that they claim once the bill has been generated I'm stuck paying it.

Upload speed issues yet again and a 6th upstream channel appears
It seems Comcast is good at lying.
I've been having upload speed issues on and off for months. Tired to get it resolved but never fully was able to. The supervisor swore up and down there is no congestion.
Today, I look and suddenly there is a 6th upstream channel. That paints a VERY different picture.
Oh and one of the upstream channels is back to 32-QAM again. I swear i hate this company and don't have time to deal with their bullshit being ill currently.

[CDV] Calls Being Sent Directly to Voicemail.
I find myself in an unusual situation. Hoping someone can point me in the right direction.
I am a Verizon FiOS customer.
I'm not sure when the problem started, but if I try to call telephone numbers that are controlled by Comcast, my calls are being sent directly to the Comcast subscriber's voicemails as opposed to ringing their telephones.
If I call the same telephone numbers using my Verizon Wireless mobile phone, the calls ring through as expected. If I call the same telephone numbers from other Verizon telephone numbers, the calls ring though as expected.
I had a friend who also a FiOS subscriber make test calls to the same telephone numbers, and they rang through as expected.
So, it looks like Comcast is processing my telephone number in some unusual manner.
Now, how do I reach out to Comcast to have them open a trouble ticket when I'm not a Comcast customer? 🤔

Xb7 wifi issue
Today, after months of working normally, my 2.4 Ghz wifi devices won't connect today. Did anything change for anyone else or is this probably an issue with my xb7 gateway? The 5Ghz devices still work normally. I have separate SSIDs and the 2.4 side still shows up, but connections do not complete. I've tried all the obvious things (sending a reset signal, power cycling, turning the radio off and on in software) with no change. The password still shows as the same.

Gig Extra Consistent 350-400 download
Upgraded to Gig Extra few weeks ago, getting 350-400 download. Occasionally will test at 500. Waiting on second tech visit. First tech replaced all fittings in home & to pole, removed a multi splitter/amp and put one 2 way splitter feeding the modem & TV. He said there were 'issues' in our area, that only a couple of local techs and one supervisor know about which is preventing some customers getting plan speed. He didn't say what those issues are. Dunnellon Florida head end, we are in Inglis/south Levy County, Gig Extra has only been available here about a month. I'm not smart enough to copy/paste a nice table to put here with signal levels. All SNRs seem what they should be, except downstream on channel 2/363MHz, is 35.8.

Modem restarts every 2.22 days, what do you think?
Hey DSLR!
Been a while since I made a post, but I do still lurk frequently :)
I have the weirdest issue going on to share with you and get some input on. I am working with Xfinity on this as well, so mostly would like some input if anyone has ever seen anything like this before so I might be able to share with them while we figure this out. I'll share back when I figure out what's going on.
Basically, I have a really decent connection (consistent 40-41dBSNR downstream, no uncorrecteds, mid-high 30's dBmV upstream) but my S33 modem happens to restart. In fact, every 2.20 to 2.26 days to be exact. I know this number to that level of accuracy because I updated an old modem poller I wrote for the MB8600 a while back. Get this though: I had that poller working on the MB8611, and was rebooting too. Though, I didn't have the uptime tracking on it, so I can't know if it was the 2.2 day reboot lifespan. I'd have to dig a little deeper into WAN availability logs to actually know that part for sure. In any case, it rebooted a lot too.
You'd think it wouldn't be that weird, but I've had the modem run for the 2.20-2.26 lifetime, and then power cycle as if a docsDevReset/similar was issued, about 4 or 5 times in a row now. Probably more, but I only recently starting logging it formally. If I restart the modem by the way, this virtual "clock" resets. I did that because I was actually engineering the reboot time so it wouldn't happen in the middle of my work day ("if I reboot this myself at X PM, then it'll restart automatically at 2AM in 2 days!") -- that's how predictable this thing is.
Whatever is triggering the reset, it's based on device uptime, not DOCSIS connection uptime. I say this because several minutes of a completely disconnected feed (and a powered modem throughout) in the middle of one of my 2.2 day cycles didn't affect this timer, or clock, let's say. Furthermore, I see nothing in the logs. If I power cycle the modem, the same event log footprint shows up. If I have Xfinity issue a "test device reset" to me, I see the same logs; the S33 doesn't report a technician reset in the event logs; they look the same.
I had a truck roll yesterday, and the technician told me basically everything looked great. He looked at the signals on my end and we even cross-referenced his event logs with the Grafana pages I have (and the corresponding restarts), and we both decided nothing was really going wrong with the line. Radio wise, the signal is great. He just did your usual preventative stuff like reterminating connectors, removing a MoCA filter, checking drop feed losses, what have you. He even moved my feed "upstream" on the tap so my upstream would be lower just in case transient noise was causing the modem to resync somehow. I really appreciated his attention to detail here.
I have a failover with another provider so it's not a big deal necessarily, but I do find it kinda annoying and would like Xfinity to address the problem in case my modem keeps trying to update to a new device firmware version, or something, and it keeps failing.
What do you think?

Has Comcast suspended data usage meter?
I wonder if it’s just my experience, Bay Area or more areas nationwide. I haven’t gotten data usage since December.
In my area AT&T Fiber is pretty competitive though it’s limited to single family homes or brand new MDUs.
Though I saw in my previous apartment rental complex last year Comcast deploying fiber deeper to my neighborhood to increase upload capacity. In my current place I noticed going from 5 to 6 US channels.

[Equip] Does this explain why my speeds are so slow?
Xfinity did some upgrading in the area. When the lights came back on, they really bumped the speed on the old DOCSIS 3.0 modem, pretty much to the limit it could handle. I got excited and on a lark found I was eligible for up to 1Gb service. (W00t!) For $10 more than what I was already paying for, I could get 600Mb/20Mb and started the checkout procedure. I failed the modem check before you purchase, it was just too outdated. I found a great deal at local store for an Arris SB8200.
The walled garden is no more, you have to use the Xfinity App from a smart phone to get the modem up and installed. That took 5 minutes, no biggie. I got all excited again and boosted up to the 600Mb/20mb plan. I check out my cart, get my confirmation e-mail and the SB8200 reboots. Once back online I did a direct wired speed test via gigabit Ethernet and a brand new CAT6e cable aaaaannnnnnndddd.....
My upstream is dead on fast @20Mb, the download, not so much. The best it pulls is 50% of my 600Mb speed tier. I go nosing in the modem's event log and find these lines you see above.
*Thinking* it's a provisioning problem, I give Xfinity a call. They can't figure it out, had to authorize overrides, but ultimately had a great cozy chat with 2 lvl-3 techs and appointments for two truck rolls. One for the plant management, the other for a house tech to come investigate the stuff around/in the house.
Color me stupid, but am I off the mark by thinking this is a provisioning problem? The two techs attempted to re-provision twice, and it wouldn't stick. I'm not convinced a truck roll will do it. What say you all?
