my guess here is that you don't have a dhcp server running in the wireless router.
Your wireless pc needs an ip address assigned by the router before you can get the internet connection.
I have a dlink router and dhcp was not enabled by default. Its rather simple to enable and setup a list of ip addresses to use.
Hope this helps.
Definitely use ipconfig /all to see if your network adapter has an ip address assigned to it and if it does, make sure its in the same address space as your router. For instance, if your router is setup as 192.168.0.1, then you should have a list of ip addresses starting with a number higher than the .1 your router is setup as...example....192.168.0.2 through 192.168.0.10 will give your systems a range of 8 ip addresses to be assigned to workstations.
