Thanks for posting on the community. It's nice to have you here.
I'm sorry you are having issues with turning on the Super Hub 2ac.
It sounds like you might have put the Super Hub into modem mode where the wireless is disabled.
To enable the wireless, you can log back into the router by using 192.168.100.1 or you can complete a factory reset if that doesn't work. Just be mindful that if you factory reset the router, the settings will revert back to default.
