Why You Don't Need MU-MIMO

    On my network are a Galaxy S6 Edge+ and a OnePlus 5T, both of which claim MU-MIMO support. Also a recently retired Galaxy S7 Edge.

    After reading this article, I'm wondering... should I be disabling MU-MIMO on the RT-AC88U?

    The OnePlus, at least, is consistently getting a 866Mbps link rate.

    No need to wonder. Try an experiment and see.

    Tested, seems to depend on the device.

    OnePlus 5T gets 866Mbps link speed reguardless of the router MU-MIMO setting.
    Samsung Galaxy 6 Edge+ and Galaxy 7 Edge both drop to 433Mbps when MU-MIMO is enabled. However, the Android WiFi Speed Test is getting slightly better results with it *enabled* on the Galaxy S7 Edge even with the lower link rate (but horrible either way). I think there might be a latency improvement when it switches to only use 1 stream. My ping times to android devices are horrible (many > 100ms!) while I'm getting 1-2ms to Chromecasts and Rokus.

    Thanks for posting the results. You are seeing results similar to those in the ariticle, i.e. might help a little bit, regardless of fallback to single stream.
