Tonight I was playing my PS3 and in a game I noticed that my ping was very high (400) when it is usually 120. My brother was sitting next to me with his Macbook open so I told him to shut his Macbook for a second. Sure enough we watched as my ping dropped from 400 to the 100's. He went upstairs and then opened his Macbook again and then my ping went back up to the 300's. I went upstairs and noticed that my mother was on her laptop too .. and my Macbook was on upstairs, not to mention my iPhone was on too. I currently have a 3-4 year old Linksys Wireless-G router - do I need to upgrade? There's obviously too much people using the wireless network which is clogging it up right? What about the N-routers? I know Mac's are configured for them but not sure about our non-Mac laptops in the house, and I know the PS3 only supports the G routers. Also, I noticed that since my brothers have been home from college with their laptops I have a hard time viewing HD videos on Youtube and whatnot. I was looking at the Apple AEBSwGE or the Linksys that support 2.4GHz and 5GHz together but not sure if those would be overkill. Can someone help?! Thanks!
