[H-GEN] Ubuntu problem - NetworkManager

[Peter Robinson]

Hi,
I am running Ubuntu 10.10 and I have a problem with the network manager 
- when I am connected via ethernet it
also connects via wireless. I am sure that didn't happen in the old 
version - i.e. it used to be the case that if I was connected via 
ethernet it wouldn't also try to connect via wireless - it would only 
try that if I pulled the ethernet plug.

Any idea on how to configure the network manager to stop this?
