It's got a link on the network card, but I can't ping anything, browse the web, see SMB shares, or anything. I set up the IPs in the same subnet and all. I don't know what info to share, so if that's not enough, please complain.
Did you receive the IP from a DHCP server or manually set it?
If you manually set it you may have to also manually put in a route and default getway.
/sbin/route add <parameters>
running /sbin/route add will list ouput the help screen with the other parameters you have to enter.
Hope this helps...
