Network Connection

If the TeleBox device's router cannot connect to the external network, you can connect the box to your laptop via a physical Ethernet cable and then set the network adapter to "Share with other computers."

Below are the detailed steps for sharing the internet connection through the network adapter, applicable to Windows, macOS, and Ubuntu systems.

Windows System Settings​

Step 1: Ensure Network Connection is Normal​

  • Primary Network Adapter: Used to connect to the internet (e.g., Wi-Fi or Ethernet).
  • Secondary Network Adapter: Provides the shared network to other devices (e.g., another Ethernet port or wireless adapter).

Step 2: Open Network Adapter Settings​

  1. Press Win + R, type ncpa.cpl, and press Enter.
  2. In the Network Connections window that appears, locate the primary network adapter (the one connected to the internet).

Step 3: Enable Internet Sharing​

  1. Right-click on the primary network adapter and select "Properties".
  2. Switch to the "Sharing" tab.
  3. Check "Allow other network users to connect through this computer's Internet connection."
  4. In the dropdown menu, select the secondary network adapter (e.g., "Ethernet 2").
  5. Click OK.

Step 4: Connect Target Devices​

  • Via Ethernet Cable Sharing: Connect another device to the secondary network adapter using an Ethernet cable.
  • Via Wireless Adapter Sharing: Connect another device to the computer's configured wireless hotspot.

macOS System Settings​

Step 1: Open System Settings​

  1. Click the Apple menu in the top-left corner and select "System Settings" or "System Preferences".
  2. Go to the "Sharing" menu.

Step 2: Enable Internet Sharing​

  1. In the Sharing menu, find "Internet Sharing" and do not check it immediately.
  2. Configure the settings on the right:
    • Share your connection from: Select the primary network adapter (e.g., Wi-Fi or Ethernet).
    • To computers using: Select the secondary network adapter (e.g., Ethernet, Wi-Fi, or Bluetooth PAN).
  3. Check "Internet Sharing", and the system will prompt for confirmation. Click Start.

Step 3: Configure Wireless Sharing (Optional)​

  • If sharing via Wi-Fi:
    1. Click "Wi-Fi Options".
    2. Set the network name, channel, and security type (WPA2 recommended).
    3. Click OK.

Ubuntu System Settings​

Step 1: Ensure Network Connection is Normal​

  • Primary Network Adapter: Used to connect to the internet (e.g., Wi-Fi or Ethernet).
  • Secondary Network Adapter: Used to share the network with other devices.

Step 2: Open Network Settings​

  1. Click the Network icon in the top-right corner of the screen and select "Settings" or "Network Settings".
  2. In the Network settings, select your secondary network adapter (e.g., Ethernet).

Step 3: Configure Sharing​

  1. In the settings for the secondary network adapter, click the gear icon.
  2. In the popup window:
    • Switch to the "IPv4 Settings" tab.
    • In the Method dropdown menu, select "Shared to other computers."
  3. Click Apply to save the settings.

Step 4: Start Network Sharing​

  • Ensure the target device is connected via Ethernet cable or wireless to the secondary network adapter. Ubuntu will automatically enable DHCP to assign IP addresses.

Important Notes​

  1. IP Address Allocation: After enabling sharing, the system will automatically act as a DHCP server, assigning IP addresses to connected devices.
  2. Firewall Configuration: Ensure the firewall allows shared network traffic. If necessary, manually add exception rules.
  3. Sharing Restrictions: Some corporate or campus networks may prohibit internet sharing. Please confirm network policies in advance.
  4. Performance Impact: Sharing the network may cause a decrease in the host computer's network performance, especially when multiple devices are connected.

After completing the above steps, the laptop and TeleBox device will be able to share the same network.
