I have a LG 4G LTE USB Modem VL600 and when disconnecting keep getting a wmc 107 error saying I cannot disconnect. What causes this and how can I correct it?

Good afternoon vic16.

I understand how inconvenient it can be not to be able to disconnect your Internet connection, as I'm sure you don't want it constantly running.  From what you described, it sounds like you have more than one modem on your computer.  You should make sure you only have one Internet connection.  Also, please make sure you have the latest software version, which is VL600ZV4.  If you do not have this version, you can download at

I trust this information is helpful!

Thank you,
