Hi,
Just a thought, but do you have a Wireless Router? If you don't have a Wireless Router, then your Wirless card in your laptop has no way to connect to anything. The signal has to transmit to something. I don't see any mention of a wireless router in your post. Things don't connect without a connection point, i.e a wireless router, in this case, and your PC would have to be connected to the router via an ethernet cable for you to access anything, ping addresses, or anything else. Also, unless there is some need for you to have static addresses it's easier to just set TCP/IP to DHCP on your machines, and DHCP on your router to connect and do whatever you need to do.
