I'm having trouble with my Ethernet connection. I've already checked that my router and cable are fine, so I think the problem lies elsewhere. I'm using an Asus a320m-f motherboard. When I try to run the command "sudo service network-manager restart", it tells me "failed to restart network-manager.service: Unit network-manager.service not found." I also tried setting up a PCIe Wi-Fi card that I had previously configured, and while it showed up in the hardware listing with 'UNCLAIMED' at the top, it doesn't appear in the settings app for Wi-Fi. Just to clarify, I'm running Ubuntu.

You might want to try enabling the Network Manager service before attempting to restart it. Sometimes, it needs to be activated first. If you find it's not installed, you can usually install it via the terminal. Let me know if you need help finding the right commands!
First off, make sure you clarify which distro you're using if you didn't already—this context can really help. The error message "network-manager.service not found" suggests that the Network Manager might not be installed on your system, or there's some typo in the command. Keep in mind, not every Linux distro uses the Network Manager. Also, I’d avoid jumping straight to restarting services unless you know they're the problem. But yeah, it’s common to restart services as a first troubleshooting step.
