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 new home. The comcast guy did a test using his tools and was able to get around 900mbps (wired) but when I run the test (speedtest.net) using the C7800, I am getting around 400mbps (wired.) and Wifi is around 100mbps. I haven't messed with the router settings much except just changing the wifi SSID and password. Is there some other setting I could mess with? I was thinking it could be my network card on my PC but that wouldn't explain my slow wifi speeds so I'm thinking

Internal throughput tests on cable gateway devices (modem plus router) are known to be inconsistent and unreliable.  Best to test wired throughput from a PC running the native operating system test application from Ookla.  Avoid testing through a web browser if possible.  There could still be a problem with the Ethernet connection on your PC.  Updated drivers maybe?  Bad cables?  On the Wi-Fi side, if you are connecting to the 2.4 GHz band, the 100 Mbps value is reasonably good.  Not so for the 5 GHz band.  It should be in the neighborhood of 300 Mbps.

Since you moved, have you done a full default reset on the C7800?  You should check the firmware on your C7800 and see how it compares to the Netgear web page here:  https://kb.netgear.com/000036375/What-s-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router.
