[Nighthawk X6S EX8000] Intermittent signal loss
Issue
Every 12 hours my devices will lose the signal from my EX8000.
Every 12 hours from the first signal loss, after restarting the router/extender. For example if the first time happens at 13:33, the next time will be 01:33, then 13:33, then 01:33, and so on.
The signal loss is complete, as in my network drops and anything I'm doing that requires constant signal will stop working for 4 to 30 seconds. I have tested using Twitch.tv, Netflix, Primevideo, Youtube and most reliably online gaming.
Troubleshooting
- Factory reset done twice.
- 3 different firmware have been installed to check if firmware error. Router/extender is currently on firmware version V1.0.1.240
- Tried different devices; PC, laptop, smartphone and tablet. They all lose connection at the same time.
- Checked both wireless and wired.
- The router/extender is at most 5 meters away from the devices, with no walls between them. The PC is 1 meter away.

At first I believed it was a problem on my PC's side, but after trying several different things, and no finding anything in my Event Viewer logs until AFTER the network reconnects, I finally understood it wasn't my PC which is what I use the most.
To check this I connected all my devices (PC, Laptop, Smartphone and Tablet) directly to Zyxel 8702, firmware 1.00(AAJX.14) and everything works fine. I of course connected them all to the EX8000 as well, and they all lost signal every 12 hours.

Help
What do I do? I bought this device in April 2019 and I did not use the internet for things that needed a constant signal so I did not know that this was an issue for the longest time. When I finally found out about the issue, randomly, as I was watching a stream on Twitch.tv, it still took me a very long time to figure out what device was causing this. As I said earlier, I thought it was my PC (which it was not).
2 things to try based off your pictures that I noticed your using dfs 5ghz for the backhaul and the 2.4ghz backhaul as well
1. factory reset the extender. Reinstall it using the installation assistant but during the reinstall uncheck the "extend 2.4ghz" box.
You'll still be able to use the 2.4ghz but it won't use it as failover for if there's issues on the 5hgz.
2. make sure the backhaul isn't using the dfs channels. It could be that there's a random dfs broadcast in your area and if so, the extender and router are required to switch off those channels for a period of time. you could be getting the drops when it switches back and forth or over the 2.4ghz.

When it goes down, are you able to log into the extender and view its status page? (get a screen snip)
That can show us a couple things.
1. whether the extender is still working
2. whether the backhaul link to the router is still working
A couple things I can recommend trying.
1. factory reset the extender. During the reinstall, uncheck the "extend 2.4gh" network option. this disables the extender using the 2.4ghz signal as failover for the 5ghz. 2.4ghz is slow and sensitive to interference. If something is causing the 5ghz to drop and the 2.4gh failover is running, it can create issues.
2. go into the router and set the extender with a static ip address. Maybe for some reason the router's dhcp/ip address lease time is expiring and not renewing.
I will do as you ask. At 00:48 tonight my connection will drop and I will remember to be logged inn at 00:47 and see what is going on.
I will take a screenshot or maybe a video so I do not miss anything.
After this, I will set the static ip.
If the static ip do not help, I will do another factory reset and uncheck the "extend 2.4gh" network option.
Sometime before 01:00 tonight I will make the first update on the screenshot/video and I will change to static ip.
I will not be able to know if the problem is fixed or at least temporary fixed until 12 hours after that.
Thanks for the inputs. I will do them all and get back here with an update.
Good luck!
