Hi @jaydenpope . You said the internet is flashing red. The only red light on the Netcomm is the power light. Do you have a NBN box with flashing red light? If so, means your phone line is not connected to NBN network.
Settings for Netcomm:
First select your INTERNET SERVICE: VDSL or Ethernet WAN
(VDSL for FTTB/FTTN. Ethernet WAN for FTTC, FTTP, HFC)
Select CONNECTION TYPE: PPPoE
Username + @tpg.com.au and password
VLAN tag: 2 (if FTTP, leave both as -1)
