Wi-Fi seems to be not working without Ethernet connected

[mrfloppy]

I installed a nighly Build. 

over nmtui i added an wifi connection.

Both the Wired and the Wifi connection get an IP from my router.

i can connect ssh over the ip from both.

But if i disconnect the wired cable, also the Wifi connection gets lost.

If i connect again the Wifi is also here.

i want to use only the wifi.

Whats wrong?

 

greets Thomas
