AFAIK, it is still in testing stages in select areas;

It's still a mystery. Keep your eye out on retail available routers, they may be available sooner. YMMV. I wanted it *yesterday* too, just like we want everything else in life these days....

Re: WiFi 6

I called 1800comcast and asked if  I could upgrade my XB6 and the rep said it wasn't available yet.  She also tried to tell me it was only for 2.5GB service.  I think she is uninformed.

Re: WiFi 6

I have friends within Comcast and I've been trying to get my hands on the XB-7 modem myself here in Michigan. From everything I know, its not in mass-market yet, its getting rolled out in stages in different areas. They said that it will be sometime in the 1st quarter of 2020 (By March at the latest). I also heard from my friend and also a rep at the local Xfinity store that they should be getting some in about the 3rd week of January!

Re: WiFi 6

Man I can’t help but wait this should put us in the same bracket or close to fiber for gaming hoping we get symmetrical upload speeds now and low latency for gaming man it’s about time Comcast because playing call of duty you can’t compete with fiber players

Don't hold your breath on that part. DOCSIS 3.1 / plant infrastructure currently is not capable of it.

Re: WiFi 6

Are you serious so what’s the reason of having 2000mbps with 40upload? Not going to work
Expert

Re: WiFi 6

@Cj3290  No sir, I'm not kidding. I cant speak for Comcast as I am not an employee. But I do know RF and DOCSIS, and I can state this;

 

The current upstream / return path bandwidth spectrum allocation on DOCSIS is physically limited. It's the nature of the beast. This is why there isn't as much flexibility with offering faster upload speeds compared to the download.

 

Here is an informative article about the future for the upstream bandwidth capability for DOCSIS based systems;

http://www.multichannel.com/news/distribution/comcast-eyes-upstream-expansion-it-pulls-fiber-deeper/...

They do offer a 2 gigabit (with symmetrical speeds) FTTH (Fiber To The Home) service in some areas.

 

You can do some research on Google on "full duplex", "OFDM", and "mid split".

Re: WiFi 6

I will do that if that’s the case I will be let down at least give us 300 to 500 upload but we will see in the coming weeks or months

As stated, it's not possible at this time. Comcast does not yet offer DOCSIS 3.1 / OFDM for the upstream.

 

With the current allocated frequency spectum, there are a max of 4 upstream channels.

 

A current single 64 QAM modulated, 6.4 MHz-wide, 5.120 MSym/sec upstream channel supports a raw data rate of approximately 30.72 Mbps and a real-world throughput of approximately 27 Mbps.  27 Mbps x4 channels = 108.

100 Mbps or so is possible as long as no one else on a 300 or more customer node is not using bandwidth. Not happening. It is a shared medium. 200 or more will never be possible even with 4 channels.

Re: WiFi 6

Ya but we should atleast see a 100mbps upload on gigabit internet
New Poster

Re: WiFi 6

Exactly that’s how I feel especially if this new modem support 2.5 gig speeds if they don’t have the upload to go with it it will be a failure compared to other companies with fiber I’m a Comcast guy I want them to win because I can’t get fiber in my area lol

You probably misheard. One port is 2.5 gig the others 1 gig.

Please re-visit my post. Physics are physics.... Sorry that I couldn't tell you what it is that you want to hear. The future is coming. Just not quite yet.

Wouldn't the XB7 offer better wifi performance with WiFi7?

Sure, but that can't change the physical limitations with the ISP's upload capability / capacity now can it @RobertWy ... ?? Re-read this thread. I don't think that you are *getting it*....

I read it but I'm not sure why Comcast would provide the XB7 if it can't do what it seems to do?

You still don't get it. A gateway device can't change physics / network / DOCSIS metrics. Were talking UPLOAD capability physics here. I give up.....

OK, I get it.  I understand that the XB7 is limited to what the infrastructure can support.
