I recently switched to wifi in my house for several reasons, and it's been a long, confusing road getting my Xbox set up like it used to be on my straightforward cable connection. I was previously unable to even FTP in to my Xbox unless I disabled my Wireless, but that has since been fixed. Next step--is it possible to share my wireless connection with my Xbox as well so I can use RSS feeds, play on Xlink, etc?

My setup is as follows: My mom's computer (comp A) has the router connected to it. My computer (comp draws internet from the router via Wireless NIC. I have a normal NIC in comp B as well, and it has a crossover cable going into my Xbox. Wireless connection's IP is set to 192.168.0.100. DNS is set to 192.168.0.1. Normal NIC is set to 192.168.1.2, and thus Xbox IP is set to 192.168.1.3.

When I try to check the box that says "allow other users to connect using this connection" and select the NIC going to the Xbox, Windows tells me my LAN adapter will be set to 192.168.0.1. I tried clicking yes anyway, and after a little while, it tells me an error occured: A LAN connection is already configured with the IP address that is required for IP addressing. My head really hurts at this point, so if someone wants to step in and take the reins, please, feel free. I'm sure it's some stupid little problem, but I'm too tired to make any more attempts at it.
