WiiM Ultra is loosing Wlan connection

[Falkensteiner]

I work with a Telekom Speedport Pro router. The firewall and AP isolation cannot be switched off on this router. If I reconnect both the router and the WiiM Ultra after losing the Wi-Fi connection through restart, the connection works perfectly. After a few hours, however, the Wi-Fi connection is lost again. When I use the WiiM app again, it finds the WiiM devices, but says that the devices are offline. I have already given the WiiM Ultra a static IP address.

Hi and welcome @Falkensteiner, are you absolutely sure about this?

If there really was working access point isolation between all clients across all protocols the the WiiM Home app would never be able to detect the WiiM Ultra. But apparently it does, at least initially. I know, I once tried it in our corporate Wi-Fi network.

I don't have a good explanation from the top of my head.

I have already given the WiiM Ultra a static IP address.

How did you assign the static IP address? I'm not a fan of manually entering a fixed IP address into the WiiM Home app. Not at all. I'm all for reserving an IP address in the router's DHCP setup, but just leave the WiiM Ultra setting at automatic. If client isolation was the root cause then a fixed IP address won't change anything, anyway.

Which exactly is your router model? At a first glance it seems like there is an entire family of Telekom Speedport Pro routers. And I'd love to tell you something else but get a Fritz!Box.
