[SOLVED] Network seems to be dropping randomly

paulbono · 2020-01-24 00:32:53

Not sure what I did exactly, I am experiencing random drops in my connection. Sometimes it's when I'm visiting google with just a search in the address bar with firefox. Other times it's just a curl

I'm wired(enp0s5) using network manager. Here's the status' from systemd.

and I have a bunch of these in dmesg

I assume this means I configured something wrong or didn't configure something. But any suggestions would be appreciated.

Now I'm not sure why I have dhcpcd enabled.

Zod · 2020-01-24 01:03:47

$ systemctl list-unit-files --state=enabled

I've disabled dhcpcd since I posted. Things appear to be running better but here is the output. I'd appreciate a second look

Looks good to me, drive it around a bit and if it seems ok don't forget to mark the thread solved.
