Problem regarding dhcp and FreeBSD 4.10 on a laptop

[Scott Key]

I have a Toshiba Satellite that used to run Win 98 until I got fed up and installed FreeBSD. This is my first FreeBSD installation, though I received help from a few people more knowledgable than I. The problem I am having is this: I have comcast broadband internet on a Linksys Wireless-G Gateway Modem/Router. I have two other computers that run windows, both of which have no problem using dhcp to obtain their IP addresses. For reasons that I have been unable to figure out after days of searching the internet, DHCP will assign a proper IP when pccard_ifconfig is set to use it in the rc.conf. The problem is that I am unable to get past the network. I can ping within the network to my hearts content, and if pinging my router and other computers was entertaining for more than five seconds, I'd be dandy. I have tried setting static IP's, I've tried manually adding the route's needed into the routing table, but NOTHING thus far has allowed be get outside the network. I contacted my cable company, who dutifully reported to me that they have no idea what FreeBSD is, anything other than Windows or Mac, and they are useless. In any event, I hope that some help can be provided in this matter. Everything else with FreeBSD works wonderfully, but for some reason, it simply will not allow me access the internet. Just to clarify, the PCcard is being recognized by FreeBSD, I added it in, it works fine. I have configured rc.conf to include a pccard_ifconfig (currently it's set to DHCP, which seems to be setting the appropriate ip address). Any help that could be offered would be most appreciated.
