Windows does not load the WWAN adapter driver. Additionally, you receive 
an error message that resembles the following: 
Windows cannot load the device driver for this hardware because a previous 
instance of the device driver is still in memory.

Consider the following scenario: 

•  You have a Windows 7-based or Windows Server 2008 R2-based 

computer that uses a third-party Wireless Wide Area Network (WWAN) 
adapter. 

•  You plug a SIM card into the WWAN adapter and then connect to the 

network by using the adapter. 

•  You put the computer into sleep mode. 
•  You remove the SIM card from the WWAN adapter, and then you plug 

the SIM card back into the adapter.

•  You resume the computer from sleep mode.
