Asus RT-N66u

After some time my wifi was to poor. I added the Asus router as an access point. And kept the 3500 as the master router. Later on I got two Unifi AP Pro. I moved the Asus router to the basement and flashed it with Advanced Tomato and disabled wifi. This is the setup I have used for almost 5 years now. I recently upgraded my internet to 250Mbit and noticed that the throughput was bad. I wanted something better.
