Hi Jeff,
I have been running FC2 with a wireless LAN card and encountered similar trouble changing LANS before I figured out how the network profile system works.
Are you using a static IP address or are you using DHCP? Are you trying to use both cards at the same time or one at a time? Are you able to ping the laptop's IP address from another computer on the LAN?
Is the link light on the LAN card is also lighting up?
The first thing that I would check, if the routing table is OK when unable to connect, is the net mask. If it is wrong, you may not actually be on the same IP network that the other computers are on even though you are connected to the same physical network wiring.
You might also try a different patch cable to connect the laptop to the network port or switch. A defective cable can cause trouble.
Hopefully, this helps.
William
