This will not happen. Straight out. Why because all major broadband companies still have and operate earlier tech in the Nodes and Headends. If you don't know what that is, google it. Hence, the 3.0 which is relatively fully operational in XFINITY, Verizon, ATT, spectrum and Cox will be coherent in the next 5 to 6 years. But hey. Maybe your area is using different tech from all of us around the 🇺🇸. I do work for one of those companiesWink and worked at Verizon for 4 years in their NY headend. 👍

I work for xfinity as a cable tech. These will work on xfinity. Only downside is it's refurbished. If Mac address of refurbished unit is still tied to an account, it will be an issue to add modem to your account.

Working in cable you still see the occasional docsis 2 modem in the homes... Doubt they will ban docsis 3 anytime soon. Also 16 channels should be good for up to 500mbps download if you pay for higher speed you should really look for more channel bonding or docsis3.1 if anyone is curious

Quote from jasesun23 :
I ended up just buying it. I'll hook this new/refub one up since it is slightly better 16/4 vs the sb6141 which is 8x4, and it is on Xfinitys approved list in my area. It won't have any effect on my speed since both modems can handle 50 down with ease. If this one goes in a year or two I'll figure it out from there.
I looked and see I bought a refurb CM500 from Tiger Direct back in Dec 2020 for $35 so this is a good deal. It replaced an Ubee DDCM3513 that was included for free in my teleworker plan at no cost. Many years later when the power supply went out on it I thought Comcast would replace the power supply for free since it was their modem but they took it off their list of equipment probably since it was end of life and tried to charge me for a power supply. They also said the service did not include a free modem. The Ubee went EOL reportedly back in 2012 so I was using it with my under 50 mbps service for 8 years past EOL without an issue. I had no improvement in speed when switching from Ubee with just 4x4 to the CM500 with 16x4 but I have something like 20 mbps down and 5 mbps upstream grandfathered service.

I may order another CM500 for this price. I'll make my current CM500 the backup unit and make this one the in use one to make sure it works during the 90 day warranty. Equipment does die. One of my Roku units recently started have HDMI output issues and after that my very old and reliable Asus router died. I had spares for both.

I really hate to spend $100 for a better cable modem that supports speeds I am unlikely to ever want to pay more for and that with one lightening strike or bad brown out could be destroyed. A recent brown out appears to have induced flickering in two LED ceiling lights in my kitchen. I buy Home Depot's store brand LEDs when I can for their 3 year in store swap out warranty. This will be the 3rd time I replaced one of them for no extra charge.

I suspect that trying to get Comcast to allow me to swap back my Ubee may not be possible. Since no Ubee is in their supported list I could not say it was a supported Ubee model. I wonder if I could say any supported model since it did have whatever provisioning in it that Comcast last provided.

1many cable ISPs remove modems as they go forward. Some Docsis 3.0 modems are already being removed from supported modems lists.

I used a Zoom 5341J modem when it was on the approved list but now it is no longer on the list but my modem still works with Xfinity.

Why would you buy a 3.0 modem when 3.1 has been available for years?

I have 1.2 gigabit and was told this will not work by the pimple faced chad at xfinity store. Can anyone confirm?
You need a DOCSIS 3.1 modem - this is DOCSIS 3.0
Comcast also has an approved list, you can't just use any modem.

I hooked mine up last night and in 24 hours it lost connection twice. The line connection lights kept going red. Also noticed it was super hot!

Swapped back to my old Linksys and no issues. Too bad because I was able to utilize the 400mbps connection but can't rely on it.

Anyone else having issues? Maybe I got a bad one? I guess it was returned for a reason...

Although I was able to activate the modem using the xfinity app and connect to the internet using the wifi router, the xfinity app shows the modem is offline. Anyone seeing this?

Check this out: https://www.reddit.com/r/Comcast/...ow_end_of/ [reddit.com]

FOR NEW ACCOUNTS Comcast no longer supports Motorola SB6121 (DOCSIS 3.0, 4x4, capable of up to 343Mbps). And for that reason on ebay it goes for about $10 shipped.
I did see this joke till today. A LOT of Misinformation is posted on the website for both comcast, spectrum, and att. ALL this information is to get customers to purchase a newer device or rent their own. I don't want to play tug of war with anyone and their superior I.Q and reading skills. I work for 2 isp's 1 in the head end of 1 and the other as a Supervisor for Maintenance. We encourage people to use specific devices to " guarantee certain functionality. While I believe you in every way. There as 1000 of customers still using tech from 2010 for modems.... yes 2010. Even if a modem is refurbished it doesnt mean its good. Its just looked at. When one of those POS modems that we give out comes from the warehouse, ALL OF THESE are thrown from 1 bin to another..... really that/s how it is. The field techs throw that in their vans as well so by the time it gets to your corner of the house...... guess what.... you just a crap modem with a life span of a few weeks/months, or 1 year if lucky. The only thing is guaranteed is that, the item is "NEW TO YOU" which is the funny and disgraceful part of our job.

MY OPINION, if your company provides a free modem, get it..... why? if you live ina place with frequent storms, your $hit is probably gonna get hit soon enough. IF YOU OWN IT? money out of your pocket to replace it, IF the company owns it, Go to the nearest store and get a replacement AT NO CHARGE.

And to be honest 9 of 10 times most of you guys call customer service for wifi coverage.... the speed is guaranteed to the wire(lan), not over wifi, if the tech that went to your home to do the installation is a TRASH tech, you will NEVER get the speeds you pay for.

Now...if you get a good tech, and hes getting the speeds at the modem consistently, now it all depends now how you are distributing wifi over the home. If people expect to get FULL SPEEDS using the company equipment and you have a big house....surprise surprise, the wifi will not cover enough to give you the 2k speeds your expecting.

A lot of details are to be considered when internet is being talked about. The most important one is always going to be placement.

Good day my people
