I’m wondering what is the max speed per node.
I’ve seen techs pull 1200/100 with the XM2 meter at the tap, but what is the meter “sharing” the speed with?
Can two neighbors pull the same 1200mbps at once without impacting each other?

comcast.net email accounts
Did I miss a memo?
At one point, if I remember correctly, there was the ability to have up to 5 @comcast.net emails accounts.
I've been looking all over the Xfinity site of my account, and I cannot find the page that allows me to create, delete my @comcast.net email accounts.
Has Comcast stopped providing this service?

Xfinity Rewards
This was discussed within another topic recently...so I went ahead & signed up for the program. When I did this, one of my "offers" was a $50 Visa gift card, no strings. So I clicked on the offer & it asked a couple questions & then told me it had been submitted & I should receive it in 6-8 weeks. Not really expecting anything to come of this, I was surprised earlier this week when it showed up in my mailbox! :D I have no idea why/how I qualified for this, but I imagine it has to do with length of time being with Comcast & how many services I have - thought I'd share with everyone, in case others might find they have some good offers waiting. ;)
edit: the envelope the card came in had "xfinity mobile" on the front upper left corner, so maybe it's because I have XM...

how do I find out why gmail is bouncing
suddenly almost everything I sent out to a gmail account is bouncing. I sent a very important medical email tonight and it bounced. the error is implying high activity but when I check my IP, my Comcast assigned IP, Comcast smtp address, etc., all come back clean. I have no idea how to go about troubleshooting this. If I try to send to my gmail from other than comcast it goes thru. I use a different email than comcast but cant use their server because comcast is blocking port 25 and port 587 outside comcast so I can only send via comcast servers. With this and their new high prices I am that close to telling comcast to stuff it.

MB8600 modem - Does Xfinity enable / support link aggregation?
Okay, I seem to be finding / reading conflicting information on this...
I have Xfinity 1200 Mbps internet service. Current equipment is below:
Modem - Motorola MB8600 which has ports 1 and 2 that TECHNICALLY support link aggregation.
Wifi system - Orbi RBK753S AX4200 (bought a month ago when I was not planning to switch to gigabit yet). No 2.5 Gbps port ,but supports WAN aggregation using one of the LAN ports (via built in config option).
My question is as follows:
Does Xfinity's implementation actually support the MB8600 link aggregation (menaing both ports will be active and allow link aggregation to work) or will only 1 port work?
I am seeing mixed info about this online.
Someone who apparently is using link aggregation semi successfully with the MB8600 (not sure with which ISP) said his connection drops routinely and he has to reboot (hence I referred to it as semi successfully). Can't find the post now. :(

Has Comcast given up on RFoG?
While I'm currently a CenturyLink Fiber customer and have no interest in Comcast period (symmetrical speeds & cloning my ONT to another model fixed my latency issues).
But I have read here from some people that Comcast has stopped doing RFoG in favor of Node+0 for greenfields. Is that true?
If it's true, I'm guessing it's because RFoG can't easily handle DOCSIS 4.0 or FDX, hence why they reverted to Coax (assuming they did). IMHO EPON makes more sense for greenfield and RFoG overlays than Node+0, but I can still understand Coax may be more cost effective for a MSO.
Yes I know Comcast won't overbuild fiber to me, and I'm not asking for it. My home is from 1930 and is not in a HOA. And I wouldn't have interest in Comcast EPON anyways if another fiber ISP existed (EPON won't fix Comcast customer service).

[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.

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.

There is so much right about this article wrt Comcast
https://www.greenevillesun.com/news/local_news/county-committee-backs-glps-over-comcast-in-broadband-effort/article_33007091-45ba-5379-a9ab-5c9b08fce534.html
"We are here local. You know us. We are here for Greene County," Bowlin said. "Our product and our customer service will be better than Comcast."
"Comcast has no customer service by the way," committee member Robin Quillen responded.
Comcast also currently relies on a fiber-coaxial hybrid network which holds back the speed and stability of the network due to the outdated coaxial line run to many homes in the county, according to Bowlin.
"When Comcast built this network over 20 years ago it was state of the art, but that was 20 years ago. They have not done anything to upgrade it," committee member Dale Tucker said.
According to Bowlin, GLPS broadband system will be 100% fiber, which allows for faster speeds, download and upload speeds that are the same speed, added reliability, and the ability to increase speeds many times over if necessary in the future.
The information technology director for Greeneville City Schools, Beverly Miller, implored the committee to support GLPS in bringing better broadband options to the county.
"This community deserves better than what they are getting right now from Comcast. They have the ability and resources to do a far better job than they have, and they have chosen not to," Miller said.
I'm glad someone gets it.

What are your thought on these channels?
My MB8600 connectivity has always had the OFDM in the middle of the channel listing and I have always had some errors showing even a few minutes after a reboot.
This morning I rebooted my modem and afterwards, noticed that the OFDM has moved to the bottom of the list and after almost an hour, I am showing no errors. This is with a constant 6Mbps download stream across an IPSEC tunnel from security cameras at a remote location.
Speed tests have been erratic after the reboot with download speeds all over the place.
Could this be node+0 going live here and getting ready for the possible rumored upload increase?

[Install] Demarc Bonding
Location: Abq, NM
So I currently have a drop coming off a pole in a back alley, going over the yard, and landing on the back of the house. The drop lands on a splitter that currently only has one line coming out, that line runs along the roof and eventually enters the building, hooking into our modem. There is no grounding anywhere between the pole and the modem, which as I understand, is not correct. I realized this after wanting to move some of this stuff around and looking into what it would take. Ideally I would like the drop to land on a demarc mounted to a garden shed that's right under the pole the line comes off of. I could than bury some coax to get to the house underground and pop up on the outside of a closet where I want to relocate the modem and my network rack to. The problem is the electrical service is on the main building, not the garden shed, so how should I do this?
-Can I run a ground wire from the main building to shed? (Its got a branch circuit run to it underground, but I don't think I can take credit for bonding with that).
-Can I drive a rod at the shed and use that or does it need to be tied to the building's grounding system?
-How long can the coax run be from this new demarc at the back of the property be to the modem?
-Who owns the bonded demarc itself, me or comcast?

Fixed wireless an 'inferior product,' Comcast CEO says
https://www.lightreading.com/cable-tech/fixed-wireless-inferior-product-comcast-ceo-says-/d/d-id/775857
On the front page may have been missed by some.
They are comparing fixed wireless 5G to DSL... Completely out of touch and being smug about it.
If Verizon and T-Mobile plays their cards right they have a chance to catch Comcast with their pants down because it seems their answer is pretend it doesn't exist.

Tech Upgrade Plan
Surprised none of you have commented on this yet. This new program looks like a way to keep us from upgrading our Gateway's until once every 3 years. I received an email about this "upgraded new service" today.
Gateway Upgrade.
Subject to the Program terms, you will be eligible to receive an upgrade to your Xfinity Gateway to a more recent Xfinity Gateway, once during a three year period. For existing eligible customers who subscribe to xFi Complete, the three year period begins March 8, 2022. For eligible customers adding xFi Complete after March 8, 2022, the three year period begins on the date xFi Complete is added to your Account. Comcast will notify you when your equipment upgrade is available. To receive the upgrade you must contact Comcast to request the upgrade through the Xfinity App or through such other means as Comcast shall determine. The Gateway upgrade is limited to a more recent Gateway leased by Comcast and will include any additional or new features included with the upgraded Gateway. The upgraded Gateway will not necessarily be an upgrade to our then most advanced Gateway. The Gateway provided as an upgrade will depend on a number of factors, including your Xfinity Internet provisioned speed, the model Gateway currently leased by you, inventory, and other factors. If your then current Gateway is Comcast’s most advanced Gateway and you are eligible for an upgrade, the Gateway will not be upgraded until the next upgraded Gateway is available. Upgraded Gateways shall be subject to availability at the time of your eligibility. Comcast may in its discretion use new or refurbished equipment in connection with your upgrade. You may not substitute the benefits of this Program for cash, a cash equivalent or any other consideration.

[Speed] Considering Switch to Xfinity
Due to recent fiber price increases, I'm interested in some of the more budget friendly plans as my house is a fairly light internet user.
I live in the KC metro area and my subdivision is about 6 years old. I have a comcast pedestal in my back yard. I have opened it up (they keep it unlocked for whatever reason) and it is coax to this pedestal and nobody is currently connected to this pedestal. In my subdivision, it appears that each comcast coax pedestal serves about 4 houses. This is the extent of what I know about Comcast's infrastructure in my neighborhood.
So my question is, is there any way to learn how good the the speeds and signal quality are in my area or how loaded this area is? I dont know anyone in this area using Xfinity so I can't go run some tests at a neighbor's house.
If I get the service I will be purchasing my own MB8611 or S33 and using my own router as I will be using the 50/10 service.
Thanks for any help!

[Speed] When did Comcast raise speed of 800Mb plan to 900Mb in Atlanta
Did a speed test to my gateway today only to discover that my plan speed had been increased from 800/20Mb to 900/20Mb. I didn't know there were any speed upgrades taking place in the southeast.

Comcasts refusal to push for FTTP/FTTH why? / Upload / Midsplit
I'm sure this is probably a duplicate topic but why the hell does Comcast have a stubborn refusal to push for FTTP/FTTH? Given the fact all the issues RF has with ingress, spectrum limitations etc. with high maintenance costs, and upstream capacity problems you'd figure they want to do away with it.
The initial investment is expensive but when it's in place I bet their support costs would drop drastically, the service quality would improve drastically, and it would last for tens of years with plenty of upgrade room. IF they did they could utterly destroy any competition and likely many wouldn't push so hard for municipal broadband options which clear they want to shut down.
Heck, They probably could even lobby for money to do but they just refuse and want to stick with dying HFC networks and DOCSIS. It's really starting to show serious limitations and to correctly deeply DOCSIS 4.0 FDX is going to require moving the node very close to users. Why not just go FTTP/FFTH at that point?

MB8600 Modem - Lost an upstream channel
MB8600 Modem - Lost an upstream channel
For some reason I can tell based on the event log reported by the modem, out of 4 upstrean channels , I only see 3 now. Midco tech checked and didn't find anything wrong. There are 4 channels seen on his test meter. The 4th channel has 40dBv but modem won't show it. Not sure if that would cause these events in the modem?. Does anyone know what would be the possible cause of these ? Thanks
