If you would like to join the CVADN mesh, choose from the AREDN supported devices at https://www.arednmesh.org/content/supported-platform-matrix. Follow the instructions on that site for flashing the firmware to your node.
The first time you start the device after loading the AREDN firmware it will automatically generate a Mesh RF IP address based on the unique MAC address embedded in the device. You do not need to and should not change that address.
On the “Basic Setup” page:
Enter “CVADN” in the “SSID” field; select “183 (5915)” for the “Channel” field; and select “20 MHz” for the “Channel Width” field.
Set your node to full transmit power unless you have reason to do otherwise. Nodes on the CVADN network should be configured for “AUTO” (“0”) for “Distance to FARTHEST Neighbor”.
For the LAN configuration, I recommend strongly that you select NAT unless you plan to offer a service from your node that will be consumed by the other network users. Choose any private subnet from the 172.16-31.x.x or 192.168.x.x ranges just as you would for your home network. Do not select a LAN subnet from the 10.x.x.x range; that range is reserved for Mesh RF addresses.
Leave the “WAN” and “Advanced WAN Access” settings at their default values.
Take your node somewhere with line-of-sight to one of the backbone nodes and it should automatically join the CVADN mesh network. A device such as a laptop can be connected to the node with an Ethernet cable and will receive an IP address assignment automatically. You can also connect an Ethernet hub or a standard consumer WiFi access point to support multiple attached devices.
