I have problem with one XV3-8 in our office. It stopped accepting clients and giving minimal information about the reason. I have below event messages.
Client [xx-xx-xx-xx-xx-xx] connection with snr  failed to connect to WLAN [SSID] with reason [Previous authentication no longer valid].
AP was showing as in sync. Software version: 184.108.40.206-r3
Does anyone had similar issues?
