If you Smart Modem 2 has a blue light, it usually means the modem has switched to 4G backup mode due to a problem with your NBN connection. If the NBN problem isn't fixed, it will stay blue - doesn't make sense that you would want it to switch back to a faulty NBN connection.
What state is the modem in now, after Telstra gave you advice to switch it back to fixed network? What colour is the indicator - Green (NBN) or Blue (4G)?
When you say 'reset my modem but still not working' what do you mean? Are you not getting internet on your devices? How are your devices connected - all by Wi-Fi? If any of them can be connected by cable have you tried that to see if that gets them working - try a laptop or PC that way. If that works then you have an issue with the Wi-Fi, which might just need some settings changed in the modem. But you will have to be able to connect to the modem to make the changes - i.e. with the laptop/PC connected by cable rather than Wi-Fi.
Try a cable and see how you go, then check the label on the bottom of the modem and advise here what the Make/Model is, and further assistance can be provided. You have to help us, to let us help you.
