Mac Forums

i need some help picking my new router to work with my mac computers, iPhones, Apple TVS, and etc internet based things. i want it to be fast and it needs to have a big range because my house has 3 levels and is quite big. the router will be on the middle floor but the current router I used has a terrible range and if i have one mac on, it gives all the internet to that one and then my computers are screwed out of internet. im running on 25/25 speed connection and i want all the potential of my connection. here are the links of the products im looking at, thanks for the help !

ps: im open to other routers, these are just the top ones ive seen so far... and im have no price limit, because i want a strong and good connection for my house.
