If I restart Network-Manager manually no dhcp anytime (see network.log)
In syslog there is an error message:
dhclient: send_packet: Message too long
Thanks for your report. This is probably a dup of bug 274069 . affecting to dhcp3.
Can you try one of the following: dhclient. conf
- remove the option interface-mtu in /etc/dhcp3/
- sudo ifconfig eth0 mtu 1000
- check if your router is in full duplex mode.
Thanks.
