Orbi RBK53 cannot maximize the wifi bandwidth of Samsung Galaxy S7 at 5GHz

[049xxv]

I am using Netgear Orbi RBK53 and Samsung Galaxy S7, and there is a problem. S7 can ultilize 5GHz bandwidth up to 867Mbps, which has been proven by working with routers of other vendors. But when S7 connects to Orbi, the bandwidth is 433Mbps or lower. I have tested the bandwidth near the router, and obviously it doesn't work. Changing the region, changing the channel and changing other settings don't work, either.

bandwidth is 433Mbps or lower

It's solved. I have confirmed that the "MU-MIMO" feature of various routers is not compatible with Samsung Galaxy S7 (Edge). One must uncheck the box of "MU-MIMO" in the settings to ensure that devices with "2x2" antenna reach full bandwidth.
