Hello everyone, I have an Asus X99 Deluxe motherboard that apparently has super fast 3x3 wifi. I don't really understand this. I'm assuming it goes hand in hand with a tri-band AC router. My question is this - does that mean the motherboard wifi adapter can connect to ALL three bands on the router simultaneously or just to one band at a time ie: just one of the 5Ghz bands leaving the other 2 bands doing nothing. I need this answered so I can make a better purchase decision on a new AC router. 10 mins taking to a Best Buy Geek got me nowhere as he was more confused than I was LOL. Thanks to everyone that helps out.

It can connect to only 1 at a time. This is why the numbers on routers are such a lie. They add the bandwidth for all the radios together knowing very well that a single machine can not use all of it.

On top of this they quote numbers for 4 overlapping streams using a very dense encoding. The number of nic cards with 4 antenna is extremely small and if you have even a small amount of interference you will not get the top encoding rates to work.

The best AC router point tends to be the ones that they call 1200. This is 300 + 900. You have the best chance of the majority of your devices being able to use these.
