Can someone help me restrict my wireless network to only my computers and gaming consoles? I recently moved into an apartment and my laptop detects 3 other wireless connections besides mine. I can connect to them with ease. I do not want other people to be able to do this on my network. I've heard that I can set up passwords (which i don't know how to do) but I've heard that I'll have a problem getting online with my xbox and ps2. Pleaes help
