MODE BEFORE YOU USE IT WITH A LINUX DEVICE. Windows MODE ALSO WORKS FOR A LINUX DEVICE. THE
IDG120 DONGLE IS AT Windows MODE BY DEFAULT.
Switch to Windows Mode
The driver is already built in the most of the Linux distributions. The Linux system will show two new ports
after the USB dongle is plugged.
-CDC_ACM (/dev/tty/ACM0), the console port
-CDC_ECM (eth1 and eth2), 2x Ethernet ports (the name of the Ethernet port may be different with
different Linux distributions)
Follow the following instructions to get the IP address from the CBRS network.
-ifconfig eth1 up
-udhcpc –i eth1
Then use the command below to check if eth1 port gets the IP address
-ifconfig eth1
After eth1 gets the IP address successfully, the settings of DNS, routing and default gateway still need to be
configured correctly to access the CBRS network.
If there is a problem to get the IP address for the eth1 port, please use AT commands at console port for
the troubleshooting.
