It is a laptop. I have not been able to get it to work
on the command line.  Perhaps it would help if I remove
NetworkManager? Also, there is probably not enough in my
ifcfg-wlan0.  I can see what is my ifcfg-eth0, but what do
I put if the network is unknown (I am traveling) or I am
using DHCP?  Do you have a reference I can read?

Thanks,
