Hi,
could you check the contents of the file /run/network/ifstate ?
If its only content is like lo=lo , please try to add the two
following lines
eth0=eth0
wlan0=wlan0
then try to 'ifdown' and 'ifup' any interfaces
In the file was the following line missing so I edited it:
/wlan0=wlan0/
But no change.
Since a couple hours my LAN works, I think since I remove the
avahi-daemon, but it is not managed through the network-manager. It`s
not in the settings.
But unfortunately the /wlan0:avahi/ line in /ifconfig/ is still there,
but not the /eth0:avahi/ line. It is a coincidence?
Best regards
Patrice
