When I am at home I use wired connection on my laptop and it works fine. Then I put it to hibernate with sudo pm-hibernate
and start it up again when I am work. I am not able to connect to internet without a reboot of the machine.
I have tried:
ifconfig eth0 down
ifconfig eth0 up
But it does not help. Also:
dhclient eth0
This took a long time to run and when finished still no success. Found this in /var/log/syslog
:

Exact same thing happens when I put the laptop to hibernate at work and start it up again at home. Anyone got a clue to why I have to reboot to make wired connection work after hibernate?
I am using Mint 17
with the latest updates.
ifconfig eth0 down
before you hibernate, then hibernate, thenifconfig eth0 up
after you start it up ?
