Windows 7
Symptom 1

based computer that uses a third-party 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.
