I can't seem to be getting my full internet speed with an ethernet cable. I tied plugging the ethernet cable into a laptop right beside my desktop and the laptop was getting 1Gbps download and 30Mbps upload on the speedtest.net speed test. But when I try doing the same speed test from the same server on my desktop, I got 500Mbps download and 30Mbps upload. The speed test doesn't detect the 500Mbps directly. It starts at 60Mbps and starts climbing till the end of the speed test to reach 500Mbps. I tried booting up a live Linux disc to see if Windows was the problem, but it seems like it isn't. I then looked up my motherboard to see if it had an ethernet speed cap and it does, but at 1Gbps. It should be enough for my internet speed, right? If my motherboard isn't the problem then I don't know what is. I started a thread a few months ago and thought that the problem would be solved when I got a new motherboard, but the problem persists even after I upgraded. I also upgraded to windows 11 as my old motherboard didn't support it. The thread: https://forums..

It seems like your computer is having trouble with its network connection. You should try adding some new drivers for the Ethernet cable and see if that fixes things. Also, buying a cheaper USB stick to plug into the computer might work too. If you have an older or weak wireless card, it can sometimes send data slower than 1 Gbps.
