Currently have an archer c5 v 1.20 that drops the 5ghz band very often and slows down quite a bit under a heavy load. I'm looking to replace it with something like http://. However while looking through the various features the asus website mentions the router having mu-mimo while other websites mention that it doesn't. Is this a feature I should care about with a 20-30 device load at most given times? If it is would http:// be better or http://.
