12.04 -Can't connect to wired network

**PaulM1985** · October 15th, 2012

I have just updated and I can no longer connect my laptop to the internet through a wired connection.

Any ideas?

ifconfig gives:

Code:

eth0      Link encap:Ethernet  HWaddr 00:40:d0:5c:9f:80  
          inet6 addr: fe80::240:d0ff:fe5c:9f80/64 Scope:Link

EDIT: Just seen a similar posting to this. I don't have wicd installed.

I newly installed 12.04 and after initial working it stopped. Editing the new config by the network configuration interface doesn't work out. "ifconfig -a" still shows old data and ping doesn't work. Only thing I can do is do "sudo su -" and edit by hand. However, even then it's slower than my other computers on the network (Mac, Linux). So what's up with this ?

When you edited it, what did you do? I don't know anything about configurations so any info would be brilliant. Just being able to connect and use the internet would be enough.
