I have a M70q mini PC that is using the e1000e device driver for the ethernet connection. Whenever I attempt to ftp a file to the computer, it loses its IP address. It will regain the IP address but it will only hold on to it for a couple minutes and then it will drop again over and over. From what I've seen online, the "lost carrier" is typically something with the physical connection although I've replaced the ethernet cable multiple times and switched router ports as well.
I am using Ubuntu 22.04
