Just got mine today. Replaced a 4500. Set up was a breeze. The speedtest from within the router itself was the correct speed for my cable connection. 5g wifi, like most, is still lacking in range. 2.4g is a lot better than my 4500.
We will see how it does. My network is heavily multimedia and gaming. So between the PC's and the Rokus, and dozen other devices, we will see how it hold up.
Seem pretty snappy so far.
