Looking at the log it seems to have connected to the DHCP server ok
and acquired an IP addres.  What does
ip addr
show?

I think the errors are to do with IPV6.  Have you been playing with
IPV6?  How have you got V6 configured in the network manager settings
for the connection.

The reason it works off the live DVD is that it is a settings issue of
some sort rather than a s/w or hardware problem.
