Nighthawk AX12 RAX120v2 firmware: v1.2.8.40 dropping connection

RAX120v2 (serial start with 6K0) constantly (at least once a day) drops the internet-connection. Wifi devices disconnect, hardwired devices loose internet connection. Both lights on top of the router...

I recommend a factory reset and setup from scratch AFTER applying this FW. A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

    Did you do the factory reset as well? 

     

    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

     

    What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
    Any Wifi Neighbors near by? If so, how many?

     

    What devices do you have connected to the router?

      I think it's a Genexis bridge, but I had no problems with a different router.

      I used the LAN cable that came with the Nighthawk.
