got an idea what would force an Disassociation frame send by Android device to Ruckus access point, reason code: "Disassociated because sending STA is leaving (or has left) BSS (0x0008)? Then: deauthentication reason code: "class 2 frame received from nonauthenticated STA (0x0006)"
We experience the issue on different brands / device types all running different versions of Android. i am running Android 4.4.4 KitKat for example.
The client is not roaming, just 1 access point with a WLAN controller. All other devices that are not Android like (Windows, IOS) do not have this issue.
auth. - assoc. – 4-way handshake – wpad querries - DHCP request/offer – disassociate – (deauthenticate)
These steps repeat over and over until the Android devices display following message: "Avoided poor internet connection"
Already tested the following:
- encryption or no encryption has no effect.
- When i give the Android devices a static ip address the devices do not seem to have this issue.
- 802.11r & k are disabled on the WLANs.
- the Android advanced WiFi settings "Avoid poor connection" is no longer available on the Android devices.
