Alright, so I’m running a relatively new installation of Manjaro. The internet is indefinably slow. I should be getting around 10-20 Mbps download, but I’m lucky to get a little over 700 Kbps. This is the same in all apps. I don’t know the command to show all my system stats, so here’s some info: I use the Asus ROG Strix X570-E Gaming Motherboard which has Intel 2.5 G ethernet and Intel AX200 wifi(which doesn’t work but that’s not the point).
Can you check the network connection with the colour of the LED of the RJ45 plug ?
