RBR750: After firmware upgrade V3.2.16.22_1.4.9: IP Configuration Failure

Yesterday night I updated my router to the latest firware version "V3.2.16.22_1.4.9". After the update, most of my devices are failing to connect to the network with a message: "IP Configuration Failure". This includes a host of devices (smartphone, Macbook, smart switches). Even the sattelites wouldn't connect and the display color on the satellites have changed from white to pink.

In order to fix it, I did the following:

1. Powered off everything (including the modem)
2. Keeping the satellites disconnected, powered on the router

At this stage, some of the devices would connect, however many wouldn't, including my Android cellphone, which had previously connected successfully. 

I finally went with a factory reset & reconfigured everything, following the steps in the SmartPhone application. However, even after the reset, I still am facing the same issue.

In one of my Macbook, when I encountered the IP issue, I configured it to use DHCP with manual address & added a 192.168.X.X address. This trick seemed to temporarily resolve the problem on this mac

I would appreciate any help to resolve this. Thanks!
