Hi, let's image we are using two RB's in bridge mode, we need using the same SSID and know the MAC address of each other R52 radio.
The link is working, then I save the configuration.
If I log on the remote radio and I change SSID or MAC address in the WDS settings, I correctly loose the connection and I must restore the correct settings through serial port or ethernet port.
How can I make a script detecting the lost connection by changing configuration and restore the last working saved one?

Save current working config (/system backup save name=working )
Make a schedule of a /system backup load name=working in 10 minutes.

If it works disable/delete schedule before 10 minutes.

I have not tested it, but it may work.
