Default password/ clear password

balalay

Hi all! I have update a firmware of my zyxel GS1900-8 to 2.70. now my password does not match and none of the standard ones match. Is there a service password? The switch is hard to get to...thank you P.S. I try admin/admin, admin/1234, user/admin etc. nothing matches

Hi @balalay,

Welcome to the Zyxel community!

May I know which firmware did you upgrade from and upgrade to which version?

The default password is admin/1234 and seems like you have tried it. This may be because you changed it before. Could you help to factory default the switch first? Please press the restore button for 10s.
