There seems to be an issue with your network speed compared to your internet connection.
There seems to be an issue with your network speed compared to your internet connection.
I previously connected my PC to the router using Ethernet for a more reliable link. After a few months, my speed dropped to around 900 Mbps, which matches my billing rate. Recently, the connection became significantly slower—now at about 90 Mbps. I thought it was the cable limiting performance, but since it worked fine before, that doesn’t explain it. Changing all my Ethernet cables to Cat7 actually reduced the speed further. I then switched back to a 5E cable connected directly to the router, which resolved the internet problems and improved stability. My PC now gets over 500 Mbps on the internet, while my PC via Ethernet only manages about 1 Mbps. This inconsistency is confusing. My setup looks like this: Ethernet 5E → Router → PC. Are Cat5e and Cat7 compatible or do they interfere? Or could there be software issues on my PC? I use a Gigabyte Z390 gaming SMI MOBILE card—do you need specific drivers for it? I’ve reset my network settings on Windows 10 multiple times without fixing the issue. It’s been a long time since I’ve faced something like this. Is the internet speed on my Mac better than my PC over Ethernet?
It seems you're asking about performance details and testing methods. You want to know typical speeds on your local network, how to measure them with tools like iPerf, what connection speeds your network uses, and whether a Cat 7 cable meets Ethernet standards.
Check if it uses iperf for testing. Which operating system are you linking to? A Linux live USB can achieve high speeds.
