Question Gigabit ethernet blocks at 100 Megabits/s but only through the ethernet port

[Kacperr1]

Hi, so my problem is that as of recent (out of the blue) I noticed my downloads limiting at 10-11mb/s (100 megabits), I checked the ethernet settings and noticed that it automatically sets at 100 megabits even though I have a capable cable and router. I came to the conclusion that it's my pc's ethernet port, since when I used a family member's ethernet to USB adapter the speed was normal and I had 70-80 mb/s downloads. Is there any way to fix this so that I could avoid buying another adapter? Thanks.

ps: I updated realtek drivers, and did try changing speed & duplex.

What pc is that?
A laptop? desktop?

With desktop pc you can install a discrete pcie ethernet adapter.

99/100 the issue is the cable. You need to start troubleshooting with a new, factory made, 100% copper, round, cat5e or cat6a cable directly to your primary router.

Desktop, custom built

Yeah the thing is that it's not the cable, I use an adapter on my cable that turns it into a usb cable and the speed is okay, so if anything it's the ethernet port on my mobo

A cable working with one adapter does not guarantee working with another. It can get bent a different way when plugged into the motherboard vs the USB adapter.

I mean I'd check on a different desktop but the issue is no one in my household has one, everyone uses laptops which do not have direct ethernet ports, I still think it's an issue with my ethernet port though because I don't think the cable has any reason to randomly lower it's speed, and my mobo has some years on it by now.
