A while ago I updated my internet plan to a 5g connection, while the wifi speed reaches up to 500Mb/s on my cellphone and my laptop, the ethernet speed is as low as 60Mb/s on my machine (running ubuntu 20.04). I've tried solving this changing the ethernet (now I'm using a cat 6e and I've tried with a cat 5e) and the speed remains unchanged. This and the fact that my ps4, which is connected with ethernet, reaches up to 600Mb/s has made realize that the problem I'm facing is linnux-related. I've searched for answers in this and other forums but nothing seems to work. ethloot gives me

Besides trying with different cables and testing them in different devices, I've tried some "solutions" in this forum like this (https://ubuntuforums.org/archive/index.php/t-1048267.html) and nothing seems to work, I ran
sudo ethtool -s enp3s0 speed 1000 duplex full autoneg on and after that I lose connection and ethtool gives me

I've also tried solving it this way (https://askubuntu.com/questions/1236926/how-do-i-set-ethernet-speed-for-ubuntu-20-04-permanently) and I get the same problem as before. I really don't know what to do anymore so if someone could please help me I'd be grateful. If more information is needed please let me know.
