I use wireless fine. I used it for when I hosted my own website, and I use it to play in and host LFS servers, also no lag. Games which are bandwidth heavy, then yes, lag, but a well made game (So not CSS and such, as their net code is designed for networks and not internet) can play on wireless fine.

My desktop, the fleet is expanding. If only I wasn't lazy, I'd have it finished by now.
