2.5Gbps Plan - Arris S33 limitations on upload speeds

Less a question, but more a heads up. 

Spent about a month with Comcast on this.  Upgraded to the 2.5Gbps down/300Mbps up internet plan.   Purchased the Xfinity approved Arris S33 modem.  Was able to get 2.5Gbps down, but upload was stuck at 40Mbps up. 

After spending time with his internal documentation, Tech found out that S33 doesn't support 300 upload >>yet<<.    There were a few more Arris modems on list (suspecting all the approved ones).

Tech estimated support would be avaialble Jan/Feb 2025 since the Internet plan is so new.  Just a heads up if anyone is struggling with that.  

I got setup with a Comcast Modem as a temporary fix (and getting max speeds up/down).
