Hi LeFric , welcome in the forum.

Generally you should put the Shelly in the AP mode and enter there the new WLAN data. 
It would certainly be simpler if you give your new WLAN the data (ID and password) of the old network.
Then the Shellys connect again by themselves.
Edit:
Second chance:
I read your thread in English and I have answered you in English.
I do not know what you mean by the translation into Spanish.
I would like to ask you to continue the conversation in English if you are interested.
Forum languages are German and English.
