I saw this post but it applies to wireless connection, mine is not.
I think my device name is eth0 (now I'm at work).
The way I normally establish a connection is by running vasm network wizard, typing the host computer workgroup name and then choosing DHCP.
So I guess I should do this:
ifconfig eth0 key s:<keyName> (
no idea that to write)
ifconfig eth0 essid mshome (or "mshome"?)
ifconfig eth0 ap Auto
dhcpcd -t 25 -d eth0
Correct me if I'm wrong.
