Internet

Level 1a
I am currently trying to connect the modem but the NBN UNID1 is not showing any colour. I have followed this guide: https://www.tpg.com.au/support/nbn/problems_connect_internet_nbn
However, it is still not working. The TPG phone support and the web chat is not working either. Therefore, please provide a solution shortly. I need internet in order to work.
