GL mt300n v2 wifi not showing up

I have configured it in the past and worked perfectly fine and I put it away, a week later (today).

The previous configuration was a custom SSID, and hidden SSID. I tried connecting to it with the details I have changed it to and my devices couldn’t find the SSID or connect to it. I tried hard resetting, and no matter what no devices are able to see the SSID to configure it again.

Tried using the factory SSID to connect as well with no luck.

Whats the solution?
