Public bug reported:
I installed Ubuntu Hardy through the NetBoot installer on an Acer
AspireOne 150L. Only the base packages would install, so I had to
install ubuntu-desktop using apt-get.
I was never able to use my wireless connection if I disconnected the
ethernet one (both going through the same router), unless I ran 'sudo
ifconfig eth0 down'. I upgraded to Intrepid hoping the problem would
resolve itself, to no avail.
My wireless card is currently not connecting to the network, and the nm-
applet is not running, so I can't use it to troubleshoot, but I am
having the exact same symptoms using Hamachi VPN.
The internet works, but I can only access one connection at a time.
I have an IP address for my Hamachi connection, can list hosts, but
cannot ping or access them. However, I can access them fine using my
Windows 2003 server, also part of the same VPN.
Here is some info (only what is relevant)

This is pretty effectively crippling my work, as I am in Mexico and need to
access my PC in Canada.
