NetworkManager problems

I switched from wicd to NetworkManager about a year and a half ago and it worked flawlessly until a few months ago. Then it started having problems:

1. It configures eth0 even when no cable is plugged in.
2. It configures it with an old static address that I used to use but is no longer even in the configuration.

I've deleted all the static addresses from the config, but every time I boot NM restores that old static address.

The other problem is that when I'm on WIFI I can't get to the internet until I manually go and delete the settings for eth0. Conflicting default routes or something.

These problems have made it much less usefull than it was. My questions are, is there a way to make NM behave? What are some other recommendations for managing networking on a laptop?

I swear by dhcpcd.service -- as long as /etc/wpa_supplicant/wpa_supplicant.conf is set up correctly, it connects both ethernet & wireless automatically & very quickly.

Once the wpa_suppliant.conf is correctly configured for your network(s), all that is required is:

# systemctl enable dhcpcd.service

Of course, you must also ensure all other networking .services are disabled.
