Router Nighthawk X6 R8000, firmware V1.0.4.84 -web interface freezes

Good morning folks,

FURRYe38 try enabling Dynamic QoS as Kitsap suggested. Your "Attached Devices" page should then let you change the devices priority.

The QoS is under Setup:

To recap, the steps that lead to router web interface freezing are as follows:

1. Go into the Advanced tab;
2. Expand the Administration section;
3. Click on "Attached Devices";
4. A table of devices should appear on the right, click on a checkbox for a device you want to change its priority and click on Edit;
5. On the "Edit Device" page, select the new priority; and
6. Click Apply.

At that point,  you will see the busy icon and the web interface will freeze and will not recover. Trying to access the router through the mobile Nighthawk app (Android in my case) will also fail (i.e. the app will state the router can't be found).

The only way to get it going again is by power cycling the router.

Let me know if you can reproduce it.

Thank you all.
