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 Fail...
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:

After reserving IPs on your router, you must shut down and restart your devices. If you don't, they will retain the IP address they were initially given, until they expire, lose power or reboot. So, regarding your 40 odd devices, turn them off and restart them.
- Thanks for pointing it out. I did that today.
Appreciate all your help folks!
