@Billmanakos I had that yesterday at times that the router did not allow any new devices. But it worked again after 15-30 minutes.

@Kevin_Z The Deco app version is the 3.7.55 and the firmware version is also the latest with 1.5.1. There is still a Tp-Link 24 port switch in between and an X50 outdoor repeater via Wi-Fi. The 3 x50...

@Kevin_Z I also no longer display any clients. A restart only solves the problem for a short time. But they seem to be all connected.

@David-TP I have this version on it. But it doesn't change anything.

@David-TP Is there anything new yet? I haven't received an email yet.

@David-TP I sent it by email.It takes 21 seconds to display the network speed and 48 seconds to update the number of devices.
