Windows 10 mobile hotspot turning off on its own
Solution 1:
There are two ways of fixing this, as behind the scenes its just creating a hostednetwork. Microsoft is constantly changing its windows 10 OS and barley has documentation of its features so this might not work on your specific Windows 10 version.
1. Registry fix
There is a registry setting that determines this. Unfortunately at the time of the writing you can only increase the timeout to 120mins.
Increase WiFi Mobile Hotspot no clients timeout:
- The time-out period, in minutes, after which Internet sharing should automatically turn off if there are no longer any active clients. This node can be set to any value between 1 and 120 inclusive. A value of 0 is not supported. The default value is 5 minutes.+ A reboot may be required before changes to this node take effect.
HKLM\System\ControlSet001\Services\ICSSVC\Settings\PeerlessTimeout
Increase WiFi Mobile Hotspot no internet connection timeout:
- The time-out value, in minutes, after which Internet sharing is automatically turned off if a cellular connection is not available. This node can be set to any value between 1 and 60 inclusive. The default value is 20 minutes. A time-out is required, so a value of 0 is not supported. Changes to this node require a reboot.
HKLM\System\ControlSet001\Services\ICSSVC\Settings\PublicConnectionTimeout
2. Install Windows Configuration Designer and change the setting
- On devices running Windows 10, you can install the Windows Configuration Designer app from the Microsoft Store. To run Windows Configuration Designer on other operating systems or in languages other than English, install it from the Windows Assessment and Deployment Kit (ADK) for Windows 10.
- After creating a profile for all versions of windows search for
hotspot. You can change the settings here. Here is some documentation for it. It says that it only works on the mobile version but thats not true. I was able to apply the mobile cofigureation settings on my windows 10 x64 pro Fall-Creators-Update version.
