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 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.
- Hi, thanks for the reply. I'm getting those WiFi speeds on 5ghz and I don't think it's the cable because the Comcast guy used the same cable when he tested it using his tools. I'll try a full reset and also check to see if my network card has updated drivers, but again both WiFi and the wired connection are slow so I don't think it's something related to my PC... I have also tried speed tests on my work PC and I am getting the same results.
As for the firmware, it's the most to date version.

After you do the reset, as part of the configuration process, the following features should be disabled or left disabled until you get this issue sorted out.
- Smart Connect - Under Advanced -> Setup -> Wireless Setup
- Dynamic QOS - Under Quality of Service.
- Traffic Meter - Under Advanced -> Advanced Setup -> Traffic Meter
- Access Control - Under Advanced -> Security -> Access Control
If your ISP supports IPv6, be sure it is enabled. Under Advanced -> Advanced Setup -> IPv6

This is important. It mighty help to explain why.
When a modem/router negotiates a connection to the Internet it adapts it settings accordingly to fit in with the parameters needed for that particular Internet service provider.
Change the ISP, even your location, and you need to wipe out any previous settings.
