I've been having a shitty experience with 2.4GHz WiFi combined with Bluetooth on my late 2013 MacBook Pro Retina for ages. The Wifi performance goes to shit with multiple devices connected and the bluetooth devices stutter and disconnect. It was completely unusable in Yosemite but slightly better in some version after that. It's currently "usable" unless I do heavy downloads over 2.4GHz with a bunch of bluetooth devices connected. With 5GHz Wifi everythings fine and dandy. It's not an issue when running Windows on the machine and it's not due to congestion regarding 2.4GHz wifi networks. And it's not AP related. It's macOS related. I am also not alone in experiencing it. Not the worlds biggest issue but frustrating as hell.
