Nighthawk M6 Pro - Drops Internet After 1-2 hours

I just setup a new M6 Pro on AT&T with 5G.  I have full bars and very fast service so it’s not signal or carrier issues. I’ve done line refreshes and run AT&T’s tests and all come back saying everything works on their end.

 

The M6 says it’s connected to the internet, but it’s not - it shows it in the network map as connected and the device appears to be operating normally according to status and moving through the settings, yet no devices can get on the internet.

 

Now for troubleshooting I did the following:

1. I moved to entirely different cell tower location with 5 bars 5G, still disconnects
2. I Factory Reset, removed SIM, reset again. Making sure it’s current, did firmware check and I’m on the latest. Still disconnects from internet.
3. I disabled both ethernet & wifi sleep functions (set to sleep never) and made the power settings max so there’s no slow down. Still disconnects from Internet.
4. I connected a laptop to Ethernet, still disconnects
5. I connected a laptop to USB, still disconnects
6. I connected a EX-20 Extender via ethernet, devices connected wirelessly to the extender get disconnected and the EX-20 reports offline
7. I brought the M6 to my house and did wifi off boarding, and it still disconnects.  It shows in the network make that it’s connected via off boarding, yet no data is passing through the M6 and all connected devices report offline.
8. I tried ethernet off boarding to my ORBI RBR850, still disconnects.
9. If I connect a device after a few hours when it’s has disconnected from the internet, the new device cannot access internet, so the M6 is still disconnected even though it let me join a new device via wifi

There is clearly something wrong with the firmware that’s causing internet to SHOW connected, but no devices can reach the internet. In Network Map on the mobile app or on the M6 screen it shows everything is working just fine.

 

If I reboot the M6 (from the app) it comes back, connects and works for 1-2 hours, then disconnects. If I change a setting that requires the wifi to recycle then when it comes back it’s working for a brief period of time.

 

This device is going in a remote location and I need to it be reliable.  Has anyone had any luck keeping this thing running for more than a few hours?  I am about to return it and go in a different direction because it’s simply not reliable.

 

When it is connected it works perfectly, speeds are screaming fast, connection is stable and ping and diagnostics are all excellent.

When the issue happens, could you please try to PING a know IP address to check whether it is working. 

Please also help to capture a model.json file to confirm the WWAN side connection is still up running. Please send the log using PM.

- Logon to the webui (http://192.168.1.1 ) as an administrator
- Navigate to URL http://192.168.1.1/model.json via the same browser window
- Capture the results (by selecting all + copy) and send it back

Please also advise the FW version on your device.

Thanks
