How to choose which NIC I want to ping?

Dear Sir,

I would like to ask you how can I choose which NIC I want to be used, every time I ping through MS CMD…?

Example: I have couple of computers connected to my home network. 2 of those use double NICs. 1 10/100 UTP-Cat5 interface, and another, Wi-Fi card.

Everything works just fine, except when I am trying to ping between wireless connected PCs, the ping trace, is routed automatically through the Ethernet (wired) Interface. So, when trying to ping an IP address that belongs to a Wi-Fi connected computer, the NIC of the wire-based network, cannot find the alias.

Thanks for your time answering me.
