RAX-120: android devices fails to obtain IP address

Netgear has set up a community forum specifically for the NightHawk RAX WiFi 6 Router products. Most of the people who watch that forum are more likely to have experience with NH router products and know how to work it better than those of us who follow this router forum. Might be more likely to find someone who has a solution if the question is posted there:

Hello,

I Just purchased the RAX-120, set it up, all my home devices connected just fine. I went to device manager, renamed a few (including the device which now fails to connect ), a hour later the nighthawk app said there was a firmware update, I performed the update, and ever since my Lenovo Tab Plus with Android 11 fails to obtain an IP address.

Anyone have this issue? Or have non obvious pointers ? No, the device is not being blocked deliberately. I have the device access feature disabled.

Thanks in advance
