Hi,

I have a new Lenovo T440p on which I booted Kubuntu 14.04 from a jump
drive, but the network connection fails.  This is a wired connection that
works with the installed Win7.  Does someone know what is going on here?

Thanks,
Glenn


This looks like to me that DNS worked:

kubuntu at kubuntu:~$ ping www.google.com
PING www.google.com (173.194.46.18) 56(84) bytes of data.
>From 10.135.122.1 icmp_seq=2 Destination Host Unreachable
>From 10.135.122.1 icmp_seq=3 Destination Host Unreachable

Here is ifconfig.

Network settings shows that the ipv4 gateway is 10.135.122.1.
