The Tenda AC15 AC1900 has a built-in setting to automatically reboot the router at a non-peak time (typically 3-5am) to maintenance itself. This guide will show you how to turn that setting off or adjust it.Here is how to set this up on the router:1. First, to change the settings of the router, connect to the router by going to its default address: 192.168.1.1. Here the default router password will be needed to sign in to change settings. 2. Once signed in to the router, a menu will appear on the left side. Select System Settings. 3. When selected, the menu to the right will update. Select Auto Maintenance here. By default, this will be enabled. 4. When enabled, auto maintenance will reboot the router once per day around 3-5am, once traffic is below 3kb/s. By default, this is turned on. To turn it off, click on the left side of the slider. 5. Once turned off and saved, the router will no longer automatically reboot each day by itself.
