So right now I just have a crappy generic brand wireless router. My MAIN problem is that I'm using wireless, but my brother is always downloading porn so my internet lags like crazy. What can I do to fix this problem? Any way to restrict bandwidth to his computer wirelessly through the router or anything? I'm thinking about buying A D-link router. I heard the D-Link DIR-655 (click here) was a really good router. Would I be able to slow down ethernet connection while making my wireless internet connection faster, that way I won't lag much. Or will QOS solve this problem?
