RBR750: 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:
- Powered off everything (including the modem)
- 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!
After reading a couple of forum posts, I tried to do an experiment: I reduced the DHCP range for the LAN and reserved IPs for some of the devices. With that done, after rebooting the router, these devices would connect reliabliy every single time. Right now, I seem to have about 40 odd devices & I reserved IPs for all of them. I've restarted my router a couple of times & even after that all devices seems to connect back. In fact, I left a few devices to use DHCP and they're working correctly as well.
I am wondering if there's a bug in the router's DHCP server module that fails to work if a lot of devices tries to connect to it at the same time requesting for IPs. This would be weird because we're talking about ~40 odd devices and not like ~1000s, causing some sort of a thundering herd problem. I'm not a network expert but this is my hunch so far.
Any other ideas or experiments would be appreciated.
FURRYe38 : Yes I tried to reset by pressing the reset button for over 15sec. In fact, I've done it multiple times since yesterday. But none of these steps have helped me so far

So try a reset with a press of the RBRs reset button for 15 seconds then release. Connect 1 wired PC to the back of the RBR. Can you access the RBRs web page at 192.168.1.1?

I would try this and reload v6 FW on to the RBR:
https://kb.netgear.com/000059634/How-to-upload-firmware-to-a-NETGEAR-router-using-Windows-TFTP
Need to press the reset button for 30 seconds then release, then it send to PUT the command and upload the FW.Download the v6 FW file for the RBR first on to your wired PC:
