Enabling Ethernet on the LibreSDR
To enable Ethernet on the LibreSDR, first navigate to the config.txt file found on the SDR internal storage. Edit the "ipaddr_eth" under the "[USB_ETHERNET]" section to a IP of your choice. I used "192.168.1.10". This can be seen in the screenshot below.
Once edited, eject the drive and power cycle the SDR. Following this, navigate to the "network & internet" > "Ethernet" page in Windows, depending on your pc, you may have to manually change the IP assignment to match that of the ipaddr_eth you set earlier. To do this, click on the unidentified network showing up in the ethernet page, click the edit button next to the IP assignment section. Change it from "Automatic (DHCP)" to "Manual". Then enable IPv4 and set the address to "192.168.1.20". Then change the subnet mask to "255.255.255.0". Now click save and you should be finished.
To test the connection, open up command prompt and type "ping 192.168.1.10". If packets are being sent and received, then the connection is successful.
To use the Ethernet connection in SDR++, open the plutoSDR panel and you should see a (ip) connection. Click on this and you will be using Ethernet.
