Netgear Nighthawk CM 2050V Cable Modem
I have a Nighthawk CM 2050V cable Modem and my ISP is Xfinity/Comcast. This unit was purchased in Dec 2021 and therefore out of warranty. I am running Window 11 Home 23H.
The issue that I am experiencing is with my download/upload speeds. I am paying for 800 down/ 20-25 upload and currently, I am seeing 450-475 down and 11-12 upload. Xfinity claims that the reason for this discrepancy is due to the modem operating intermittently therefore unable to operate at the paid level. And their suggestion-naturally, is that I go with their modem. Up until 6 weeks ago this modem was running speeds consistently 800--850 down and 22-26 upload.
I have entered the Modem gateway and there is no indication of a problem- it does indicate the cable is good and i see the latest Comcast firmware update. The status lights on the Cable Modem are indicating as they should per the user manual.
Can anyone offer detail that I need to look at within the gateway settings that might offer a glimpse as to why I am not seeing the speeds that I once operated at? Thank you for reading this. I need to address this issue with Xfinity again, but I know that I need info to back up my claim.😁😁
