EX7000 AC1900 Access Point (Failed to Obtain IP Address)

Hello guys, I thought I have to comment this thread with my recent experience. I had lots of problems with my previous generation Netgear wifi range extender EX6200 performance until I got tired of firmare updates, product replacements and endless support emails and threw it away. The EX7000 I have never had any problems with, and the performance has been great until now. I actually haven't used it for about one year but today I found the need. No problems setting it up, everything ran smoothly until I noticed this evening that a firmware update is available. After firmware update I constantly receive the "failed to obtain IP address" issue regardless of how many factory resets or different configurations I try. The box is now totally useless in my environment trying to connect with a Huawei B525s router. In my view it has to be a dodgy firmware update but sadly I can't recall which version I upgraded from so I am unable to revert back to the old version regardless of the security issues it had.
