ISP Claims CM2000 Can't Handle 2.5gb?

Hey All, 

 

I'm new here, but not new to Netgear products. I love them... I hate my ISP Astound (RCN). I'm hoping for a little help or guidance here. 

 

My ISP is claiming that the Netgear Nighthawk CM2000 cannot handle speeds over 1GB according to the MAC address...

As we know, and was confirmed by Netgear Tech support via the Serial Number that it can indeed handle my ISP's 1.5GB internet plan I pay for. Netgear states it can handle up to 2.5GB. (According to speedtest, I'm only getting about 800MBS at best)

 

My question is why would an ISP argue with me and insist that according to the MAC address of the unit, that the CM2000 can only handle a 1GB connection? P.S. I've also previously gotten close to my actual speeds I paid for previously this winter, but not even close now. 

 

Could there be a legitimate issue I have somewhere on my end or with the Modem, or is this likely some ISP BS? 

 

Any help, thoughts, or guidance is welcome and appreciated!

    Supported speeds is up to the ISP and there CMTS vendors. 
    Yes, the CM2000 has a 2.5Gb WAN port in back and can handle up to that. 

     

    Are you speed testing with a wired PC connected to the back of the CM modem? 
    Also does this PC have a 2.5Gb or higher speed ethernet adapter installed? 

    What's the brand and model# of the host router when it's connected? Also this router should have a 2.5Gb or higher speed WAN and LAN ports to see anything past 900Mbps.

      Thanks for your reply! I've previously gotten these speeds with my current Modem and router setup with the same ISP. When speaking with them, they claim they cannot provide the 1.5gb I pay for because the Modem does not support it. When doing the speedtest, I'm on a desktop PC hardwired into my router, which is hardwired into the CM 2000 Modem. So naturally, I would expect a small drop, but not from what should be a 1.5gb to 750-800mbs. 

       

      And the fact my ISP claims MY equipment (the CM 2000) does not support the speed is what has me fuming. 

       

      As for your technical questions here are some answers: 

      • PC does have a 2.5 GB ethernet port cable is connected into. I've confirmed I'm on the ethernet connection and not the wifi. I have a ASUS ROG Strix Z690-E Motherboard. 

      As for my Router:

      • ASUS GT-AX6000 ROG Rapture Wireless Router. (Which claims to also support 2.5GB)

       

      I wish I even saw at least 900 MBS at this point... Let me know if you have any other thoughts FURRYe38
