Instable WIFI connections with Android devices

[peter_jannesen]

We have 3 R500 Unleashed. Running 200.5.10.0.283.

We suffer from very unstable WIFI connections from Android devices. The devices range from Samsung Tab S2, S7 Edge, Moto 4G, HTC U11 life.

When I download the logcat from a device and filter on wpa_suppliment I see the following message ‘wpa_supplicant: wlan0: CTRL-EVENT-DISCONNECTED bssid=xxxxx reason=6.’ It is always reason 6.
