Netgear Nighthawk C7800 Low Speeds on Lan and Wifi
Hi Community, I have been getting slow speeds on my C7800 from the get go. I just moved thinking that my previous place was the issue with my slow speeds but I am getting the same issues at my ne...
I have an R7800 so there may be some details that are different.
Your firmware version V6.01.07 is current.
Understand no QOS.
Understand no Smart Connect.
I also keep 20/40 coexistence disabled.
It is time to look at your cable connection power levels and your correctables/uncorrectables counts.
It is easier to copy and paste the screens to a word processing document and then attach to the reply as a PDF file. That way you do not have to wait for a moderator to approve your image file.
Is the 20/40 coexisting a setting, not sure where that is?
Also where can I find this data?

Thanks for the reply guys, I have disabled 20/40 coexisting and I have attached the the cable connection as requested in pdf format.

There is no one magic answer. When you shut off the 20/40 coexistence, run a Wi-Fi throughput test on several of your wireless devices and see if it helps the situation.
Your downstream power levels are significantly high. Netgear says they should be between -7 and +7 dBmV. The power level situation should be corrected by your service provider. Make sure the ISP checks it all the way to your gateway, not just to where the wiring enters your house. Power levels being high can be just as much of a problem as their being low.
