EX7000 Wifi Range Extender Dropping out after upgrade latest Firmware

I have been experiencing the same problem. I've had my extender online for a couple months just trying to get some coverage to the other side of the house. But it wasn't until I installed a Ring security camera on the front of the house and paired it with the extender's 2.4 mhz wi-fi frequency that I noticed a problem. The camera doesn't support the 5 mhz signal so only the 2.4 mhz signal will do. The camera worked fine for a couple days and then I checked the Ring app and saw that the camera was offline. I tried to pair the camera to the AC1900 (EX7000) again and the 2.4 wi-fi signal did not appear under available wi-fi frequencies during the pairing process. So I rebooted the EX7000 and the 2.4 mhz frequency appeared again as an option and I successfully paired the camera again. The next morning, the camera was offline again. So this time I also put my iPhone on the EX7000's frequency after repeating the above steps again and getting the camera working again. Of course, the next morning the camera was offline again. I checked my iPhone and it had jumped over to the 5 Mhz wi-fi indicating the 2.4 signal had cut off at some point during the night. I called Netgear Support and since my main router is a Netgear Nighthawk, they had me log-in to the Netgear Genie website using my ip address and go into the main router's Advanced wireless setup. They told me to change the 2.4 mhz channel from Auto to 11 and the 5.0 to 161 and that this should also affect the Extender. I went out to pair the Ring camera again and I was pleasantly surprised to see that it was already paired and operating as a result of what we did. But it's 10:00 pm now and I'm not declaring victory yet. We'll see what the morning brings. Feels too good to be true! And let me tell you that dealing with that Indian call center is stressful. I can only understand every second or third word and kept asking her to repeat things. I don't understand why companies are still putting their customers through that hell. It took three times longer than it needed too because we couldn't understand each other.
