how do i secure my wireless network?
It seems that everytime I start up my computer it picks a different network. I can't secure my network because I don't know how to do that. My network is the only one unsecured so I'm sure everyone is using mine if they're having trouble getting on their network. I hit Apply and the click on the lock but it doesn't hold. I know I'm missing a step somewhere. Please help.
