Here in Northern NJ Comcast is a quite reliable broadband provider... but in the almost 18 years we've had their service the download speed has risen to 225 Mbps, while the upload speed has remained at around 5 Mbps. In practice this doesn't seem to matter much. I assume they could potentially add additional upstream frequencies but I doubt they get many complaints about it, or that very many of their customers are even aware of the asymmetry.

Switch to their business class offering if you need the upstream. I'm also in northern NJ and on 200/20 tier. There's no technical limitation on that bandwidth restriction so long as you have a docsis 3 modem or later that can bond multiple upstream channels. However, there was a technical issue I had some months ago with a faulty Arris modem provisioning file that disabled upstream bonding across most of their models. It took an email to the CEO to sort it out (after a Reddit and DSLReports post on the matter).

  How did you figure out the root cause? Usually you can't fetch those files yourself.

    I bought 3 different Arris modems and they all bonded upstream until activated on the network through comcast's walled garden. Once activation was run the upstream sync light changed to show it was no longer bonding upstream. If a deactivated one was plugged in, again it would bond. Previously I had been on a 50/10 tier and when the new business class tiers were released they blamed my trusted old SB6121s for being too old, so I bought 2 newer ones in the SB series and had same issues. After writing the CEO and CC'ing all the techs I spoke to and including links to the threads they gave me a direct engineering contact that confirmed the issue. For the trouble they credited me out 2 months of service.
