You want to access the Internet with all your computers through the Linksys wireless router....
To determine whether the computers have a wireless card installed, go to Start->Control Panel->Network Connections. If you have a "Wireless Connection" there, then you're all set.
Secondly: On the base computer, that has the cable connection, while trying to install the software, setup intructs not to connect the router before it searches for the internet connection. It doesn't find the connection that I know is.
I'm not exactly sure what you're trying to do. You dont need to install any software to access the Internet via a router.
1. Connect the modem to the WAN-port of the router
2. (Assuming that you have a WLAN-card installed and WLAN is activated in the router: ) Access the router by entering it's IP in the PC's web browser
3. Set up the internet connection and the WEP/WPA encryption in your router and your PC's
Done.
