[SOLVED] Ethernet connection slows from 400mbps to 100mbps within a few minutes ?

My ethernet has 400mbps immediately after plugging and the adapter status for Realtek PCIe Family Controller shows that it has 1 gigabit:

But after a few minutes it slows down to 100mbps in a speedtest and the adapter status says the speed is 100mbps:

I used multiple cables to test it but a cat6 stays at 100mbps the whole time. And a crappy broken cat5e cable that i had lying around (the one that is in the pictures) begins at 400mbps and slows down to 100mbps like I said
Both cables are UTP cables and the cat6 one is a flat cable. Cat 5e cable is round
I think this is a cable issue because trying out different cables give different results. Do you have any suggestions to fix this issue?

Not sure but I bet it is. CCA cable is not allowed for any ethernet cables. It would not meet the standards. I forget exactly which standard says the metal must be copper. When the standards where written many years ago CCA cable did not exist so they do not actually say you can't use it they just say the wires need to be made out of copper.

This company appears to make great efforts to sell only certified cable so I doubt they would sell trash cables

There is an article from Commscope back from 2012 about CCA: https://www.yumpu.com/en/document/read/12317237/copper-clad-aluminum-cca-commscope

Do you think it's worth it to buy from this trusted brand over the previous cables that I have selected? The previous one had 23awg and solid. The Commscope cable only costs a bit more.

That's household electrical power using CCA and does not take high frequency issues into consideration because they just don't have to. 60Hz, for USA electrical systems, is pretty far from the frequencies used in networks. The copper cladding on he outside of the Aluminum core causes the signal to reflect within the wire. The cladding acts as a mirror and the interface between the copper and aluminum causes distortion for what signal does come thru. The longer the distance the more the signals becomes a distorted mess.

There is an article about Commscope selling their cca and steel assets to Fushi Copperweld here: https://www.cablinginstall.com/cabl...steel-assets-will-close-nc-manufacturing-site
The article says that they will continue to make GroundSmart products.
Does this mean that my cable will not be cca?

Beating a dead horse.

Just make sure the cable is copper and not CCA...

This is perfect, comes in different lengths, different colors, is genuine stranded copper, tested, guaranteed, and is a good price: https://www.computercablestore.com/10-ft-booted-cat6-network-patch-cable-black

It means you need to make sure you don't order a CCA cable. No one here can do that for you.
