Hello,
we have a problem with client connections from our mobile devices.
Mostly this occurs with the Anroid clients, but for IOS devices we have the same issue sometimes, W10 clients didn't have this issue.
The client can successfully connect to the SSID. But after sometime (mostly after wakeup from standby) the client shows connected to WiFi, but cannot communicate to the internet anymore. After disable/reenable WiFi, all is fine.
Any idea, where to start searching ?
