Unlike a router, which is a standalone device, a modem is a peripheral and depends upon a host. Connected IO Modems support Windows and Linux hosts. Each needs a driver to know how to communicate with the modem.

Setting up a modem consists of three simple steps:

1. First, install the proper driver on your host computer.


2. Then connect the modem and power it up.

3. Lastly, activate the modem and tell it where to 'communicate'

To connect, use the USB  cable, as desired, and plug in the modem until the Power LED illuminates.

To configure the driver,  follow the next step to make some additional changes for driver signature disabling:

4. Additional changes for driver signature disabling:

Please use the link below (option 2) to disable driver signature enforcement (it should be re-enabled on the next reboot):


5. Linux driver support:
