Hi @spuddo1, thanks for getting in touch with us. Hm.. it seems like the modem is in 4G back-up mode. If there’s a problem with your broadband connection, your Optus Ultra WiFi modem will automatically switch to the 4G Network where available.
To check if there is an NBN outage within your area, please check out our Network Status Page. Let me know how you go. Tina.
