If security hasn't been set you do want this to stop others leeching from your broadband, but be careful that you don't disconnect your current wireless PCs.
Now on your laptop, right click the wireless network icon on the bottom right of the page. The pop up menu should allow you to set connection options, including security type and password to match the router's settings. |
If you do happen to change a setting and find you knock your other pcs off the wireless then its possible to use a Wired connection to get back into the router.
Since you have a laptop easiest way is probably to use a bit of Cat5 cable between the router and laptop that should give you a connection to login to the router and change the settings and also give the laptop internet access if you need to come back and ask for help.
