My Book Live can't access IN SOME WAY

Some updates,

I found out the ip address is changed and I don’t know why.

After changing the path of the “My Book Live Public Share” shortcut, I can access it normally.

There shouldn’t be an IP change when hitting the reset button of My Book Live, should it?

And my mobile devices HAVE access the whole time. It’s very weird to me.

When I go to the dashboard, it says “syetem restart (4)” and “The system has restarted” 

But the green light is still flashing constantly.
