Networkmanagers keeps dropping internet connection
Hello, i have a problem with networkmanager - it keeps losing/dropping internet connection. This can happen anytime. When it happens, i check ifconfig and see my inet (ipv4) adress is missing. Only inet6 remains, but that doesn't help me. I have to reset networkmanager everytime this happens, it can become frustrating when you leave your computer overnight to work on something and next day you see that the internet connection was down for the last 6 hours. Someone advised me to switch to netifrc (i use gentoo), but i didn't like it because of wpa_supplicant. Imo, networkmanager manages wireless connection much easier. So i switched back to networkmanager. Here are some details i noticed:
when (re)starting networkmanager
Code:
* Starting NetworkManager ... [ ok ]
Connecting............... 0s [offline]
* Marking NetworkManager as inactive. It will automatically be marked
* as started after a network connection has been established.
* WARNING: NetworkManager has started, but is inactive
Code:
$ rc-update show
