Uninstall the software that came on the CD because you can configure the router directly through the web interface, this way you do not have to worry about the incompatibility issue with windows 7. Next you want to try a wired connection to one of the 4 switch LAN ports on the back of the router. Check your settings in windows networking for your wired lan card and make sure its set for DHCP ( obtain IP address automatically ). Plug the cable in and hopefully you will get an IP. Verify this by going to start, run, cmd - at the command line type ipconfig /all and look for your network card to make sure there is an IP address in the same range at the router. If the router address is 192.168.0.1; you sould see something like that, could be 192.168.0.4 or even 192.168.0.200 depending the DHCP pool and network mask. If all is well then open up your web browser and go to 192.168.0.1; log in, set a password for admin, then configure your wireless network. WPA, passkey etc. After this is done restart the router for good measure. Unplug the wired LAN, the let your wireless card find the routers name (SSID, you can change the name in the setup if you want). Allow the computer to connect to your router, since you configured it as a secured router you will be prompted to enter the same passkey you created in the setup.
