No WLAN Connection with 2.129

In release 2.118 there were no Wifi configure over the Homepage.
In the /etc/network/interfaces file is no dhcp in the wlan0 section an the wpa-config entry is missing.

In the new release 2.129 are no Wifi connection.

I had test it with an RPI3 und an RPI2 with the RPI-Wlan Stick and RPI3 Onboard Wifi.

On the Homepage the Switch Wifi go out after reload!?!?!

A better explanation would help
