XR700 Wifi disconnects

Hi all, 

 

I am continuously getting wifi dropouts for certain devices. If i reboot the router or disconnect the device from the wifi it may connect again or may not ...only to disconnect a few mins later. It appears it just does not want to hold on to an ip address. The logs are filled with DHCP lease changes. I have over 50 devices connected wirelessesly some work flawlessly and some dont. Even the devices that do not work sometimes appear to show in the device list as connected.

 

Things I have tried:

Changing all wireless settings

Setting static ips

Netgear support rep thought this was a hardware issue so I returned and purchased another one - this one is exhibiting the same behavior

 

Things that worked temporarily:

Resetting up the network with a new ssid and password and adding each device one by one. (also adding to the list of things I will not do again!) I had about 20 days of stable uptime but after I rebooted the router because DUMAOS page was not loading many tabs. It is back to exhibiting the same behavior.

 

I requested a beta firmware from the DUMAOS forum earlier today but still have not recieved any word yet. 

 

Pretty frustrated at this point and at the point of giving up and getting something else.
