make modifications on a remote station without risking to lose connection

I am looking for a way to do some modifications on a remote station without losing the connection with it. Basically i am not sure if the new config will work an i can’t risk to take down the connection.
So what i want is a cisco-ish thing: I want to issue something like “reload after 30 minutes” command, make my modifications on the “running-config”. If anything goes wrong, i just wait half an hour and everything will revert to the original config.

I have some issues with nstream on an old RB 433:
@wlan1: lost connection, not polled for too long
@wlan1 established connection on 2422, SSID AP-NAME

Just use safe mode! :smiley:

Winbox has a “SAFE MODE” button on top. Press that, and do your modifications. If after xxx minutes you do not press the safe mode again, then Winbox reverts the old config. I do not know exactly after how long, but in my case it could take up to 25 minutes.
