Get online support
It's not my modem that doesn't work, it's the NBN box itself. The NBN Box has no light for 'Online' which means there is no NBN network connection.
I reset the box already, it didn't help. I think there is something wrong with the NBN connection itself. It seems it wasn't installed properly yesterday. I can't reach customer service via chat or phone (they don't have phone support right now) was hoping they reply to tickets in the community. Thank you for trying to help.
