Wired devices lose connection randomly, one at a time. (alien.top)

I have an issue that has been wracking my brain for some years now.

We have an Asus RT-AX82U gaming router and we have our two computers hard-wired into it.

Problem: Sometimes, at seemingly random times, one of our computers will lose connection. Sometimes it's one then the other, sometimes it's just one. The connection is gone for a few seconds, and then it comes back on its own.

Question: Does anyone know why something like this would happen? I am assuming the problem is from the router to the computers themselves. I don't think the issue would be with the modem since it only affects one computer at a time.

More information:

It's very quick, so we can't really troubleshoot by the time it comes back, but it seems that the device's connection to the network stays intact but just gets disconnected from the internet
We have old (10+ years) flat, gold-plated ethernet cables from the router to the computers
Both our computers are twins. We recently built them with the exact same components. However, this issue also happened with our older computers (also built as twins)
The modem is an old modem/router in bridge mode
We have a simple network: utility -> modem -> router -> devices
This has been going on and off for a few years, it's more of a nuisance than anything, but we do get disconnected from raids and other packet-sensitive situations

Mainly, I want to know if anyone has had issues of a similar type or would know what component would cause it. I am thinking about replacing the ethernet cables soon and possibly getting a new modem that's just a modem.

Thanks in advance!

What motherboard do you have? The Intel nic has had problems dropping randomly, it could be that.
