Upload Speed

What is the upload speed expected if I signup for the 1000 Mbps plan?  What is the max upload speed offered by Xfinity?

35 to 40 Mbps up.

Re: Upload Speed

Thanks for your prompt response.  That explains why I am seeing less than 20 upload with my 600 Mbps plan.

 

Wonder when Xfinity is going to catch up with competition (AT&T)

Re: Upload Speed

While they are competitors, they are also using different technologies.  Anyway, here's some recent news on this:

Apples to oranges. 

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 speed and other types of tech.
