Great Modem - Easy Install


Arrived on time promptly form Optus, set up was very easy also. Sleek modern look also. The connection has been great, doesn't drop out at all. Perfect size and easy to hide in plain sight. Optus has done a great job with the nbn connection also, couldn't be happier. Entire process was smoothe and communication was great also. Answered all our queries about modem/nbn and helped us understand the best possible bundle for our new home.

Will this work for NBN

1 answer

It was standard issue modem around two years ago with Optus NBN. It will work with any provider as it is a generic modem. Ethernet output cable from NBN ARRIS box goes as input this modem. Note the NBN coax cable does not go into this modem.


my wifi extender WN2500RPv2 no longer works after the sagecom nbn modem was installed. Tried resetting via WSP and web but does not fix the problem. Ios device also cannot pick up connection with extender and keeps giving wrong IP address. Do i need to configure something on Sagecom modem ? Do i need to add MAC address etc ?

Is the Sagemcom new? If so, I think you have to configure everything to suit. I have a Sagemcom and its wifi is useless - keeps dropping out. I still use the Sagemcom for the phone landline but I hardwire another router from for my wifi


Thanks for reply. Yes, Sagecom modem is new; was provided as part of change from cable to NBN and was set up by service provider. What do I need to change in the configuration ?


Along with the Segemcom modem, I am using Netgear R6400 AC1750 Smart WiFi router, there is no issues so far.

Yes. I plug my landline into it and seems to work ok. Just the wifi part isn’t much good
