managing wifi on e805 ppc

so is the built-in 802.11b easy to set on the Toshiba.
because I can seem to figure that part out; either that or
their is no hot spot (service) in my area;
I live in the neighborhood of banks and hotels;
I tried to see if I can pick up near by signals even
at the airport.
But I don't know how to go about doing that.
unlike my blue device which has a LAN manager.
Bluetooth was a breeze but I am not sure about wifi.

thanks
