WWAN Stops working on L570 until rebooted

2019-03-04, 7:40 AM

I got a user who has a L570 that connect when he boots it in the morning, then after about an hour while using it the WWAN connection drops and doing error check on it gives the "mobile broadband device or sim is locked" Error. 


When the user then reboots he can use it again and it might not make an error the rest of the day.


The PC is a L570 with Windows 10 Enterprise installed and updated trough windows and Lenovo system update.


I've tried reinstalling the drivers, used different versions, but so far no luck.


Any ideas or suggestions is appreciated.
