NBN issue with latest firmware versions
I use a RBR750 with 2 satellites and they were just running perfectly. I am connected to NBN and I never needed to reboot and the connection to the internet was stable and great. Later came firmw...
It has been pointed out from the logs that there are many DHCP requests from several sources followed by a disconnect event. Thank you for this!
I now have assigned most of my devices a reserved IP address and have also enabled IPv6 on the ORBI.
Then I updated the firmware to the latest version 7.2.6.31 which never worked longer than 1 day. For the FW upgrade, I used this time the ORBI app on my phone.
Since then, no more crashes, everything runs very smoothly.
I will further monitor it, but it seems to me these frequent DHCP requests have caused the system to crash. Strange though, a DHCP request should be a very basic function...
"they found out that the modem (my Netgear RBR750) caused this issue." The RBR750 is not a modem nor does it have a built in modem. This is a router unit.
What brand and model is the NBN modem or ONT that the RBR is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6A STP is recommended.
Does the ISP support DHCP WAN configuration or something different like PPPoE?
After v.21 was loaded, did you factory reset and setup from scratch with out loading any backup configurations from file soon after the system was updated?
You’re right, the RBR750 is a router…
The Modem is from NBN and belongs to NBN, this is part of the infrastructure here. The model is G-240G-P and details can be seen here: https://apcoms.com.au/nbn-fttp-connection-box-status-lights/
From this NBN modem, I have a CAT6E cable in the walls to the centre of my house which is about 15m long. I have replaced this cable 2 times with 2 new temporary cables, but this made no difference.
My ISP supports DHCP WAN, it does not require a login and it is not PPPoE.
I did a full factory reset after v 7.2.6.21 and configured it all from scratch.
My ISP did some investigation and they said my router is causing this issue, I should try with another router. But after rolling it back to v 4.6.14.3 it just keeps working fine for months without rebooting.
With any later FW version I get this issue daily, so the only logical explanation is that the firmware causes this.
