When installing the modem you may get a message saying:
"An unidentified program (VMC) wants access to your computer, do you want to allow this?"
Please ensure you click Yes.
If you click No, this will stop the software from working correctly and the modem will not connect.
If you have clicked No then please follow the below steps
Uninstall software:
Then plug out the modem and Restart the computer
Log in if prompted
Wait for the computer to fully restart
Re-install software:
If this still did not fix the problem, you may be using an old version of the E220 modem. In this case you will need a firmware & software update which you can find here
