If you like BT stuff just ditch the 205 and get a Voyager 2110. This is a modem and wireless router and also has 4 ethernet ports. It is easy to set up and has a WEP key included as standard, (key code on label on base)
1370 WLan is not a wireless card it is an ethernet or firewire for connecting to modem by cable. if wireless then look for Intel Pro ****BG network connection. on my dell the F2 has what looks like an aerial mast with waves coming out either side and is used in conjunction with Fn to switch wireless on/off. on toolbar at bottom if you have an icon with a monitor with waves emanating then right clicking on it should show a box with all available wireless networks.
