BleepingComputer.com: Connecting A/V Equipment on the Internet

I have a computer that is connected to the internet using a wireless pci adapter. I have an ethernet cable attached to the on board NIC card and the other end goes to my a/v receiver. I need to setup internet connection sharing on the computer and a/v receiver. On the host computer I have to connections in the networking area the "wirelesss connection" and the "local area network (NIC)". The only options I have on the a/v receiver is to auto configure or manually configure the connection. I tried unsuccessfully last night what happened on the host I went into the wireless connection and clicked on "share connection". The error message that the IP is in use came up. When I set the IP address manually on the wireless connection it lost connectivity to the internet but the Local Area Connection worked. Any help would be appreciated.

If you are using a wireless router infact any router with a Network port, why are you not using that for the AV equipement. It will not need to be set for Internet connection sharing then. In my opinion ICS is a waste of time and it more often than not does not work and is very flakey.

The a/v receiver does not have wireless capability it needs to be hard wired. Secondly the modem with the wireless router attached is too far away.
