CM2050V-speed capped at 50Mb download in a 500Mb plan

Here is a KB on what firmware is installed based on the ISP.  https://kb.netgear.com/000036375/What-is-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router

 

Thanks

The CM series is a modem, not a router.

 

Which ISP is the modem connected with? 

 

What FW is installed ON the modem? 

What brand and model host wifi router is connected to the CM Modem? 

 

What speeds do you see if ethernet connected directly to the back of the CM modem with a ethernet connected PC? 

 

Please post a copy and paste of the modems connection status and event log page.

I installed this device in my house, put fiber directly on it, it registered without issues.

 

But I noticed a odd issue:

 

Any download is always capped at 50Mb/s (my plan is 500Mb/s for both downloads and uploads), but UPLOADS happen at full speed (500Mb/s).

 

I tried some troubleshooting but nothing seems to work! 

 

I suspect it might have to do with firmware (I've updated it to latest firmware), but the problem is I can't find the original firmware that came with it

 

ISP told me this router is compatilble, and they advised me to contact Netgear, which I'm doing, because it might be a software fault on device's side.

 

It seems this is a secret device only ISPs have access.

 

Who's your ISP? I'm wondering if you have it backwards as xfinity's upload max for their next gen devices (which the cm2050v isn't sadly) is 300mbps (usually hits 350mbps). The max upload for the CM2050v is 40mbps.  see here: https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2024.09.18%20Full%20List%20of%20Compatible%20Devices.pdf

So I'm wondering if you have it backwards.
