Hello NETGEAR Community,

 

We understand Comcast/Xfinity has recently issued a statement regarding your CM2050V cable modem may not achieve the full upstream speeds due to their proactive measures to address intermittent connectivity issues. Here's what we know: Comcast deployed a new CM2050V firmware around September ~ October time frame last year (2023) that provided the higher upstream speeds recently deployed by Comcast in some areas. However, Comcast has reverted the firmware update, impacting individuals who initially experienced enhanced upstream speeds, causing them to return to the speeds they had before September 2023. 

 

So, in summary:

  • For people who live in the areas where Comcast has yet to deploy the new services with higher upstream speeds, there is no impact.
  • People who received the recent increase in upstream speeds are now back to the speeds they had before September 2023.
  • Releasing a fixed firmware that restores the function that supports increased upload speeds on Xfinity is our highest priority.
     

We will provide an update once the firmware becomes available.

 

We appreciate your patience and understanding.
