Well I bought a Linksys wireless routher, and wireless PCI card, yesterday. And well it was fine last night, all games were working fine. but when I woke up this morning, the computer is recieving extreme lage. I never had lag like this before with direct cat-5 connect. And when I actually used my connection last night it was pretty late. So what I'm thinking is, maybe somone or someone(s) else in my nehiborhood is using a wireless router and PCI cards; so maybe thats why its giving me lag.
But my question is, how do is setup my wireless router to have like a password to connect or something. Just so I can block other people from using my connection? Please help, the lag on WoW is ****ing tedious.
