Nighthawk AX4 Randomly Stops Working

I purchased the Nighthawk AX4 router several weeks ago and after about a week of use I began having connectivity issues with it. It is model RAX40 with firmware V1.0.2.46_1.0.1.

 

Everything worked perfect for about a week or so, then about once a day all WiFi stops working until the router is restarted. All lights stay on and stay green on the router when this happens. On my phone, it still will show it is connected to the router, but internet does not work. On other devices such as my Nest thermostat, it shows disconnected from the router completely. There doesn't seem to be any specific time this is happening, but it seems to be when nothing is in use for a while (when I'm at work or sleeping).

 

I have read about disabling the AX setting, which did not help at all.

 

Has anyone had this problem or have any idea how to fix it?

    I am having the same issue. Mine is related to DHCP. The router randomly reassigns bad IP addresses to devices. Changing my devices to use a static IP and configuring them properly solved the issue. Kind of annoying that this is happening but this is a workaround if you are having this same issue. Next time this happens, take note of the IP addresses on your devices before you restart the router. If they are completely wrong, change them to static and configure them and the device should work fine without having to restart the router.

      How do I change device IPs to static? The only static IP setting I can find is for the internet. I'm really not sure how all that stuff works.

        This would be done from each individual device unfortunately. Almost all devices give you the option to manually set IP settings. So no matter if it's a TV, a laptop, a smartphone, etc, in the process of connecting the device to a wifi network, there should be the option to set the IP address manually. If you're using default settings on the router, it's internal IP should be 192.168.1.1. On each device, set the default gateway to that address (192.168.1.1 if default settings), then set the subnet mask to 255.255.255.0 and set the device's IP address to something like 192.168.1.XXX (XXX = 100-255). The device should also ask for a DNS server. Just use the same address as the default gateway (again, 192.168.1.1 if using default router settings)
