Optus Sagemcom 5366 LTE and Airport base stations

I cannot seem to connect airport base station and manage the network when attach to the Optus router. Optus (fibre to node) has 4 LAN ports. Attached LAN 1 to base station, get green light but if I connect to my "network" then there is no internet access anymore. I can connect wirelessly to router direct but losing strength (cement floors between 2 stories)

Did have a UniFi attached but hit by lightening last night and I think they are blown.

It's tricky to work but my advice is to disconnect the Optus device and put it in a drawer for those times they ask you to connect it to diagnose why your Internet is down. You don't need it - with one exception which I'll get to in a minute.


Before our NBN was installed (HFC not FTTN) I tried in vain to get a clear answer to the problem of getting a new wi-fi modem when I already had a mature and extensive Airport wi-fi network. The problem being that I wasn't going to connect the 50+ devices I have all to the new wi-fi router just to use the Optus device which was in any case inferior to mine. In fact they gave me an 802.11N wi-fi when I already had the AC Airport Extreme so you can see how impressed I was.


The ISPs are giving or selling a wi-fi modem to every NBN user, which is great if you don't already have a wi-fi network, but a pain in the posterior if you have one already.


All I did the day we were connected to Optus NBN, and after the tech had departed having seen that I had the Internet working, was disconnect the Optus modem and plug the ethernet cable from my Airport router's WAN port into the black NBN box. The NBN box is in fact a modem - and the one that connects to the Internet. It's just like the old cable one you had to abandon when NBN was connected. When I connected the cable, I had my existing network running directly into the NBN box.


The model is Internet > NBN box/modem > Airport Extreme > Local Network


The exception mentioned above about the Optus modem is that you have to use it if you want to retain your fixed phone. The NBN requires your house phone to plug into the Phone socket of the ISP device (it's a green socket on my Optus device) and without it you don't get the phone to work.


However, as our household has a number of iPhones (in fact one each) we long ago abandoned our fixed phone. Perhaps you might have also? I'm told, but have never tested it, that if you connect the Optus device to your Airport router (in a LAN port) and the phone to the green socket that will be sufficient for the house phone to work.


None of this helps you get your current setup to work, but as I said you don't have to do it that way, despite what the ISPs tell you.

Not sure that I understand what you are trying to accomplish here.


Are you saying that you were using one or more UniFi access points connected to the Optus router to provide your WiFi signal.......and the UniFi access points are not working.......so you are trying to connect the AirPort Base Station to the Optus router to provide your network WiFi signal?


If yes, what model of AirPort base station do you have? If no, please provide more information on how you are trying to set up the AirPort base station.


Did you reset the AirPort base station back to factory default settings........before.......you connected it to the Optus router? If not, that would have been the first thing that you would want to do.


Will you be using a Mac to reconfigure the AirPort Base Station, or will you be using an iPhone or iPad to set things up?
