After some R&D I went with the ASUS RT-AC66U B1 AC 1750 - Great router, don't think I can go wrong with it! These dual band routers have me a little confused, are you supposed to have a different SSID for each frequency or is it best to keep it different? I was under the assumption 1 SSID and the frequency would be chosen automatically depending on what is best for where you are in the house?
