Here's what I have: d-link dir-601, 1 desktop pc (dell, vista), 2 nexus tablets, 2 nextbook tablets, 1 ps3, 1 xbox360, 1 iphone4, 1 landline phone, 1 cordless phone and comcast high speed internet. We don't game much but we watch a lot of netflix/youtube. I'm not sure if I need to get an extender, a new router or any of the many other options available that I have limited knowledge of, lol.
