First you have to setup the router: (this is for the netgear WGR614, not sure about the SuperHubs)
In Advanced > Wireless Settings on the left menu, enable wireless and SSID and apply the settings.
Then find Setup > Wireless Settings on the left menu and setup an SSID so you see that name on your laptops, then enable security, either WEP or WPA, and lastly put in a security key (password) and apply the settings.
I've got a Netgear router supplied by VM and all those settings are in the 'Wireless Settings' options.
Once you've enabled the Wireless adapter on each laptop (either by a key combination or switch) your laptops should be able to see the SSID and when you connect it will ask for the security key, enter that and it should connect (may ask to remember the key).
Normally that's the process
