Well you got me pulling my hair out now and it isn't my computer. Usually pretty straightforward making a connection. I hope somebody smarter can come up with a solution, only thing I can suggest is uninstall everything at computer end and redo it.
Have you actually "Connected" to the wireless network? In other words, have you run the wireless adapter's software, scanned for "Available Wireless Networks", found and highlighted the one that matches your router's SSID (network name) and selected the option to "Connect" to it? Once "connected", the little icon will get its "halo" to indicate it is connected to that network and it should then get its correct IP address by DHCP from the router. You should then have internet access.
