WPA is more usefull tho O.O i used it when i still was on wireless xD now i got my own connection all the way :3 but if you're using a stick (for accesing the internet without cable most people will understand what i mean) you can just open the window then double click on your connection choose the WEP and enter your pass and done. If you're the gateway in your home do what the dude above me said.
