Use the OpenThread Border Router (OTBR) Web GUI to configure and form, join, or check the status of a Thread network.
Access the Web GUI
If the OTBR is serving as a
Wi-Fi access point, access the Web GUI by
attaching to the OTBR access point and visiting the static wlan0
IPv4 address
configured during that setup.
If the OTBR is not serving as a Wi-Fi access point:
- Make sure Network Address Translation is configured for OTBR.
- Access the Web GUI by visiting the OTBR's local IPv4 address in a browser window.

Join a Thread network
Use the Join menu option to scan for and join an existing Thread network.
Form a Thread network
Use the Form menu option to create a new Thread network.
- Replace all default values on the Form page—except for the On-Mesh Prefix—to ensure a secure Thread network.
- Select FORM.
- After the network forms, confirm by checking the Status menu option or
running
sudo wpanctl status
on the command line of the OTBR:wpan0 => [ "NCP:State" => "associated" "Daemon:Enabled" => true "NCP:Version" => "OPENTHREAD/g4ccc23a5-dirty; NRF52840; Sep 22 2017 10:44:07" "Daemon:Version" => "0.08.00d (/033c369; Sep 20 2017 21:06:17)" "Config:NCP:DriverName" => "spinel" "NCP:HardwareAddress" => [F872DF9CD5AE4DCE] "NCP:Channel" => 15 "Network:NodeType" => "leader" "Network:Name" => "OpenThreadGuide" "Network:XPANID" => 0xDEAD1111DEAD2222 "Network:PANID" => 0xDEAD "IPv6:LinkLocalAddress" => "fe80::287f:87ca:f4b3:498a" "IPv6:MeshLocalAddress" => "fdde:ad11:11de:0:74d0:6fc9:6be6:3582" "IPv6:MeshLocalPrefix" => "fdde:ad11:11de::/64" "com.nestlabs.internal:Network:AllowingJoin" => false ]
- Check the
wpan0
interface for the global IPv6 address with the On-Mesh Prefix set during network formation:
The On-Mesh Prefix global address is used by child nodes to identify the Border Router that is responsible for forwarding traffic out of the network. The other addresses correspond to the Mesh-Local and Link-Local IPv6 addresses of the NCP node within the Thread network.ifconfig wpan0
wpan0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1280 inet6 fdde:ad11:11de:0:74d0:6fc9:6be6:3582 prefixlen 64 scopeid 0x0<global> inet6 fe80::287f:87ca:f4b3:498a prefixlen 64 scopeid 0x20<link> inet6 fd11:22::287f:87ca:f4b3:498a prefixlen 64 scopeid 0x0<global>
Check the Status
The Status menu option is the equivalent of the sudo wpanctl status
command. It displays status information for the Border Router NCP node, along
with the status of services like wpantund
and mDNS.
