    Re: No wired connection

    I had this problem and installing WICD or adding:

    Code:
    auto eth0
iface eth0 inet dhcp
    to /etc/network/interfaces fixed the problem

    It may be the return of this bug: https://bugs.launchpad.net/ubuntu/+source/dhcp3/+bug/61989

    Really it's a bug in your router, which is reporting the incorrect MTU value. However Network Manager *should* be smart enough to ignore any value below 576, but is not.

    eth1 seems to be the wired interface.. and its MTU seems correct..are you able to ping gateway?

    This has fixed it.

    I ran the command in the bug report

    Code:
    sudo ifconfig eth0 mtu 1500
    Thank you so much for that suggestion. I never would have found it without you.
