My computers are not able to reach my wireless router with cables. However, computer 1 has a wireless card and can connect successfully to the router wirelessly. Computer 2 does not have a wireless card, but it has a regular NIC. Can I network Computer 2 with Computer 1 using the unused NIC’s in both computers?

Once networked, can they share the internet connection that Computer 1 currently gets wirelessly?

If so, I suppose it would involve using a cross-over cable. Well — suppose I also have an 8-port switch lying around that I could plug both computers into. Would that let me still connect both machines (without the need of making a crossover cable)?

If this is possible, I just need to know what settings to change in the TCP/IP settings, I suppose, for each machine.

Assume that the router is 192.168.1.1, computer 1 is 192.168.0.100 and computer 2 is 192.168.0.101.

You may assume both machines are running XP. I can translate this to linux later.

Thanks,
Riven
