When a few clients are leaving an AP at the same point, our network on an specific access point is dropping.
Is there anything we can do about? It's on 5Ghz, an MR32.
Several flavors of WiFi (or 802.11 as nerds call it). Sometimes old legacy flavors such as 802.11b can sometimes downgrade the whole WiFi WLAN as the AP has to serve up data using old out-of-date mechanisms. Turn off support for old poo poo devices. Only enable 802.11n (circa 2009 technology) and up? Something like that.... Give that a try.
