The modem that we've provided on our NBN service is for free, so the refund will not be possible.
You may use your own modem/router, but the home phone will not work if you are in an FTTN/FTTC/FTTB/HFC technology since the VoIP settings is embedded in its firmware.
Our network Engineers are still investigating this concern and will provide updates once available.
The Xbox is getting a new IP every time they reconnect.
There is 2 ways to fix this.
Just connect the Xbox and check the MAC in the client list under the Network -> LAN settings:
Under Address Reservation on the same page
Then add the IP address in the DMZ:
If using a different IP when setting this up, you will need to restart the Xbox and the Modem so both release the existing IP address that is leased.
Hi @Gryph, we can see that you are on a Dynamic IP plan. This is normal behaviour. When the modem reboots, their WAN IP will change and Xbox will need to re-establish its session to Xbox live. This is normal for any authenticated ott service not just xbox (e.g. Netflix, Amazon Video, Stan etc).
Your connection looks very stable at the moment. How often do you reboot the modem?
