Are the laptops Vista or Windows XP? I don't run Vista unfortunately! Make sure the modem is plugged into router too!
See this page for configuring the router:

You need to set region to UK and Channel to
11! Also the SSID is just a name to identify YOUR router so call it what you want, then enable WPA-PSK option and you'll probably be asked to enter a key, this could be the tricky part so see here if you get stuck:

The WPA-PSK key is basically a password (between 8 and 63 characters) that only YOU should know, so make up something and write it down so you can use it configure the laptops, it can be upper/lowercase and contain numbers eg: MyWPAKEY1234545
So what you've done is set the router up with an a new SSID and locked it with an encrypted password that only you can use to gain access to the router.
In the router settings just check this section, Maintenance > Router Status and you should see an IP Address and two Domain Name Server adresses, if so this means the router has connected to your modem!
Now the laptops! Most have wireless connections so make sure they are enabled (see your laptops manual for enabling wireless) and usually have an icon in the System Tray for the settings. But for now try the first link I posted then scroll down the page to the
Configuring Wireless Clients and try to follow that for configuring the laptops!
The SSID will be the name you used when you setup the router so look for that in the list of Wireless connections and the WPA-PSK key will be the one you made up and hopefully wrote down! Once those are in the laptop should connect to the router and be able to connect to the internet! Same applies for the secomd laptop, see how you go and post back if stuck!
