For the record: in my case, it appears modifying: --- a/NetworkManager/NetworkManager.conf +++ b/NetworkManager/NetworkManager.conf @@ -1,5 +1,6 @@ [main] plugins=ifupdown,keyfile +rc-manager=file [ifupdown] managed=false when no other dns-helper is installed, solves both problems (screw up both resolv.conf and interface switch wired/wireless between bots). Not really obvious even after reading `man 5 NetworkManager.conf'. -- Cristian
