I have forgotten my password to Zyxel8751-2,4ghz

Hi @Anifor

To better help you solve your issue, please help to provide your model's name.

Additionally, if you forget the SSID's password, please check the device's sticker if it has the SSID's password. The info you provided is more likely a default SSID, so the device's sticker might has some information. Or, you may access to the device's local web GUI to change the SSID's password.
