Access Web Admin Panel

Make sure the current firmware type is Thread. You can access the GL-S20 Web Admin Panel by opening your web browser and navigating to either "http://gl-s20-otbr/" or the IP address assigned by the upper-layer device, as long as you are on the same network.

INTERNET

Internet

Read the below instruction to learn how to connect the GL-S20 to the Internet.

You can configure and manage GL-S20's networking settings by clicking INTERNET on the left side of the Web Admin Panel.

It supports 2 ways to connect to the Internet as listed below:

Method 1: Connect to the Internet via an Ethernet cable

Ethernet

To establish an Ethernet connection, use an Ethernet cable to connect the WAN port of the GL-S20 to the LAN port of an up stream device.

On the left side of the Web Admin Panel → INTERNET → Internet → Ethernet card.

Protocol

There are 2 types of protocols: DHCP (Dynamic Host Configuration Protocol) and Static IP. Click Modify to change the settings.

• DHCP: DHCP is the default and most common protocol. It is a network management protocol used on Internet Protocol (IP) networks for automatically assigning IP addresses and other communication parameters to devices connected to the network using a client-server architecture.
• Static: Static is required if your need a fixed IP address to connect or you want to configure the network information such as IP address, Gateway, Netmask manually.

Method 2: Connect to the Internet via an existing Wi-Fi

Using Wi-Fi means connecting the device to another existing wireless network.

You can change Wi-Fi settings on the left side of Web Admin Panel → INTERNET → Internet→ Wi-Fi card.

Basic steps

1. Click Connect.

   

2. Select a Network you want to connect from the pop-up window. (If the desired network is not listed, click Join Other Network at the top.)

   

3. Enter the network passwords.

   

4. Click the Apply button.

5. Wait for a moment, if you have successfully connected to the network, you will see the screen below:

   

Wi-Fi Advanced Settings

On the Wi-Fi Join Card, there are 2 additional settings you can use.

• Lock BSSID: If this option is enabled, the device will only connect to the Access Point (AP) corresponding to the BSSID you selected when switching to a network using this SSID.
• Manually set static IP: If this option is enabled, you can configure the network information such as IP address, Gateway, Netmask manually.

Manage Known Networks

To manage known networks, click Switch Network.

Or click Connect.

On the Known Network section

- To delete a known network: Click the trash icon.

- To configure the network: Click the settings icon.

Join Other Network

If the SSID is not in the Available Networks list, or the network you want to connect is hidden, you can click Join Other Network.

• SSID: Enter the network's SSID.
• Security: Select one of these options.
• None: Select it if the network doesn't require a password.
• WPA/WPA2/WPA3: Select it if the network requires a password. Enter the password below.

Finally, Click Apply.

Reconnection

In the following cases, the device will try to connect to Wi-Fi every once in a while. You can turn off the reconnection manually, and for SSID/password errors, please delete it in Known Network.

1. The wrong SSID/password was entered during the process of Wi-Fi, after the first failed connection.
2. After connecting to the Wi-Fi of the Primary router, the device moves out of the signal range of the Primary router.
3. After connecting to the Wi-Fi of the Primary router, the upstream router changed the SSID/password, or restricted the connection.

Failover

On the left side of the, Web Admin Panel → INTERNET → Failover

The GL-S20 can be connected to the Internet in multiple ways, such as Ethernet and Wi-Fi.

When one type of Internet access is not available, it can automatically switch to another type of Internet access in specified time. (Ethernet is the highest priority )

The GL-S20 will use ping to track the connection to destination IP to a determine if the interface is available.

The setting of Interface Status Tracking Method

• Enable Interface Status Track: You can disable the interface status tracking, and the router will use the physical status of the interface (such as whether the network cable is plugged in or not).
• Track Interval: Check every five minutes.
• Change to Failure Condition: The fault is detected after five consecutive failures.
• Change to Available Condition: It is judged to be a successful state after two unsuccessful attempts.
• IPV4 Track IP: Configure the IPV4 address you want to detect.
• IPV6 Track IP: Configure the IPV6 address you want to detect

Thread Mesh

Thread Network

On the left side of the Web Admin Panel → THREAD MESH → Thread Network

You can configure and manage Thread Network settings in Thread Network page.

Parameter meaning

• EUI-64: Unique device identifier, hexadecimal number of 8 bytes in length.
• Ext Mac: The device extension address, a unique identifier in the Thread network, is a hexadecimal number of 8 bytes in length. The extended address is randomly generated and will be re-randomized when the system is restored to factory settings.
• Thread Version: Current thread protocol version.
• Tx Power: Transmit power, -24~20 dBm, default is 6 dBm.
• Network Name: Thread network name, 1 to 16 characters long, used to generate PSKc (Pre-Shared Key for the Commissioner), default format - <3 characters after MAC address>.
• PAN ID: IEEE 802.15.4 MAC layer unique identifier, default value is 2 bytes after the MAC address in hexadecimal format.
• Extended PAN ID: Thread network extension PAN ID for PSKc generation.
• Network Key: Thread network key, a hexadecimal number of 16 bytes in length.
• Channel: Thread network channel, 11~26, default value is 26.

Network Name is generated based on the MAC address of the device, PAN ID/ Extended PAN ID/ Network Key is generated randomly.

Create a new Thread network

You can create a new network directly by using the default configuration and clicking Enable. After a new network is created, the status of the GL-S20 will be changed from Detached to Leader.

Note: If your Thread network has the same configuration as other Thread networks, the GL-S20 will automatically join that network.

Manual Setup

If you want to set some parameters manually, you can configure them by clicking on the Manual Setup.You can modify the contents in the popup window.

How to join a Thread Network

There are two methods for connecting the GL-S20 to an existing network.

Method 1: Join the network by using Network Key

Click Join Network. The GL-S20 will start scanning the available Thread networks nearby.

In the pop-up window, select the Thread network you want to join. Enter its Network Key and click Apply.

Method 2: Join the network by using the Commissioner

1. Use another GL-S20 as the Commissioner (please refer to the Thread Commissioning page guide), enter the Joiner EUI64 and Joiner Credential of the GL-S20 to be connected to the network.
2. Click on the "Join Network" on the GL-S20 to be connected to the network, select "Join With Commissioner" in the pop-up window, enter the Joiner Credential and apply it.

Thread Commissioning

On this screen, you can add new devices to the network. GL-S20 supports adding a large number of devices.

• The Joiners card: The list shows Joiners that are ready to be added to the network.

• The Commission Records card: Shows entry history of joiners' network.

• For Joined/Timeout devices, click the three-dot icon → Rejoin. The selected device will be added back to the Joiners list, waiting for next Commissioning.

  

• For all the devices with the Join Fail status, you can click Rejoin All to move then back to Joiners list altogether.

  

Add a single device

Click the Add button and a pop-up window will appear to add.

• Joiner EUI-64: Joiner's EUI-64 or type * to match all Joiners.
• Joiner Credential: The device credentials to be added must be a string containing all uppercase letters and numbers and must not contain the letters I, O, Q and Z, between 6 and 32 characters in length.
• Joiner Timeout: Joiner access timeout, during which a Joiner can access the network using valid credentials.

Add devices in batches

If your device's service provider has set different Joiner credentials for each Thread device, you will need this feature when deploying. Clicking Export to download the template or export the saved Joiner list, fill in or add the Joiner EUI64 and Joiner Credential, then click Add → Batch Add to import.

Please note that the number of joiners added cannot exceed 50

Advanced Thread network settings

You can use different advanced configurations related to Thread networking.

Backbone Routers

The Backbone Router (BBR) function is primarily used to receive multicast inbound/outbound requests. Refer to (Thread Boder Router-THread 1.2 Multicast) for experimentation.
