Lumia 920 internet sharing

Hello Vergers!

I have a problem with my Nokia Lumia 920. It is about the internet sharing or hotspot function.

The connection to my computer will only be open for a limited amount of time, often 2-3 minutes, and after this time, the connection stops. The phone doesen´t show any error message nor does the computer.

When the connections fails for no reason, i can reconnect and it looses the connection shortly after.

Any of you, who has a solution, or an idea of what can cause this?

Thank you!

(I am updated to the latest version on phone and computer, and the problem happens on both Mac and windows machines. )
