So lately I been lagging when playing games, watching a video, or sometimes just web browsing due to my cousin using the internet in the living room (which is the furthest place from my router). My family was thinking of getting 2 separate internet connections so I would stop lagging. I'm not sure if this is a good idea or if I should just get a new router. I was thinking of getting the ASUS RT-N66U. The current router I have now is a TRENDnet TEW-711BR. To sum it all up, I'm laggy cause of too many people on my wifi. What should I do?
