How to set up Wireless connections

Question

Computing for Dummies.HiI need an indepth explanation on how to connect to WIFI on a Toshiba Satellite Pro 6000 series. It has an Integrated Wireless Lan apparently. I have checked this and it is correct but I cannot connect to it.Can someone explain in detail what I need to do/have and how to go about connecting. This is a secondhand laptop that i have just bought off Trade Me (NZ)and I don't know anything about the Wireless side of it. When I click on the Wireless Connection icon in the System tray it says "No Wireless Networks were found in range".If I go to set up it asks me for a SSID network name.Also on this page is a button that says - Automatically assign a network key (recommended)Next page says - Use a USB flash drive (recommended) or Setup a network manuallyIt also tells me something about the Firewall not allowing the connection????Please help.CheersDummy # 1
