I recently been having trouble with my internet going down and up a lot on my computer. When I check speed-test.com, it says speeds range from super fast 750+ MBPS all the way down to just 5-10 MBPS. I tried resetting my router and using a new cable, but nothing seems to have worked permanently. This is definitely happening on the wire that goes from my modem to my PC, not the Wi-Fi itself. Last night, I did some testing for about five minutes: when I un-plugged the wire and turned on the Wi-Fi, I had a steady 250+ MBPS. But as soon as I plugged the wire back in, it would go all over the place again. Any help would be very helpful to me right now. Please note that I am fairly computer savvy but not really good at fixing networks, so if you can give me some specific steps, I will appreciate them a lot. Thanks!! Here is my equipment list: My PC has an Asus motherboard with a GPU called EVGA FTW 3090 TI and runs Windows 10. My modem is a Netgear C7000v2 which has the firmware version V1.03.08. My internet provider is Comcast/Xfinity. I have five computers connected to my PC right now. This whole thing happens while using the wired connection. One extra note: last night, when I tried to fix it, I unplugged and replugged all wires too, and also disconnected all devices from the modem. That didn't seem to help at all.

Check your computer to make sure there is only one network adapter turned on, whether it's wired or wireless. I think you are just using the wired one. Open Command Prompt type ipconfig /all (without quotes) and paste the results here. You don't have to write all that down again, just copy and share the output.
