Guide to Setting up Sub-routers

In today’s era of the Internet of Everything, the industrial sector’s demand for network stability and high speed is increasing day by day. 4G industrial wireless routers and the emerging 4G/5G industrial wireless mobile routers, with their powerful data transmission capabilities, wide coverage and excellent stability, have become the preferred solutions in many industrial application scenarios. However, to fully realize the potential of these high-end routing devices, the correct sub-router setup is of vital importance. This article provides an in-depth yet easy-to-understand introduction on how to set up routing for 4G/5G industrial wireless routers to ensure that your network environment is both efficient and stable.

Before delving into the setup steps, let’s first have a basic understanding of 4G/5G industrial wireless routers. This type of router is specially designed for harsh industrial environments and features dust-proof, water-proof, high-temperature resistance, and shock resistance, making it capable of adapting to various complex working conditions. They not only support 4G LTE networks, but some high-end models are also compatible with 5G NR (New Wireless) technology, providing faster download and upload speeds and lower latency, which is crucial for industrial applications that require real-time data transmission and remote monitoring.

4G/5G industrial wireless mobile routers usually come with powerful built-in firewall and VPN functions to ensure the security of data transmission. At the same time, they support multiple communication protocols, facilitating seamless integration with different devices and meeting diverse industrial needs.

• Equipment inspection: Ensure that both the main router (i.e., 4G/5G industrial wireless router) and the sub-routers are in good working condition. Check if the antenna connection is firm and if the power supply is normal.

• Network environment analysis: Understand the existing network architecture and determine the optimal placement of sub-routers to maximize signal coverage and minimize interference.

• IP address planning: To avoid IP conflicts, plan the IP address range of the main router and sub-routers in advance to ensure a clear network topology.

• Login information: Prepare the management account and password of the main router, as well as the default login information of the sub-routers that may be needed.

• 1. Connect to the sub-router
  First, connect the WAN port (wide area network port) of the sub-router to the LAN port (local Area network port) of the main router via an Ethernet cable. If the sub-router supports wireless relay function, it is also possible to consider connecting via wireless means, but attention should be paid to signal stability and bandwidth loss.

• 2. Log in to the sub-router management interface
  Connect to the default Wi-Fi of the sub-router using a computer or mobile device (usually the name and password are on the label at the bottom of the router), open a browser, enter the management IP address of the sub-router (the default IP is usually in the router manual), and log in to the management interface.

• 3. Configure the WAN port Settings
  In the management interface of the sub-router, find the “Network Settings” or “WAN Port Settings” option. Select the connection type according to your requirements
  Dynamic IP: If the main router has enabled the DHCP service, the sub-routers should select to dynamically obtain IP addresses.
  Static IP: If a fixed IP is required, manually enter the static IP address, subnet mask, gateway and DNS server assigned by the main router.
  Wireless Relay/Bridge: If connecting wirelessly, select this mode, search for and connect to the Wi-Fi of the main router, and enter the correct password.

• 4. Set up the LAN port and Wi-Fi
  LAN port Settings: To avoid IP conflicts, modify the LAN port IP address of the sub-router to ensure that it is in the same network segment as the main router but does not conflict.
  Wi-Fi Settings: Configure the Wi-Fi name (SSID) and password of the sub-router, and consider using the latest encryption standards such as WPA3 to enhance security.

• 5. Advanced Settings and Optimization
  DHCP service: Enable or disable the DHCP service of the sub-router as needed. If it is disabled, IP addresses need to be manually assigned to the connected devices.
  QoS (Quality of Service) : For critical services in industrial applications, such as video surveillance and remote control, QoS rules are set to prioritize the bandwidth guarantee of these services.
  Firewall and Access Control: Configure firewall rules based on security policies to restrict unnecessary access and enhance network security.

• 6. Save and restart
  After completing all the Settings, remember to click the “Save” or “Apply” button, and then restart the sub-router as prompted to make the Settings take effect.

• Regular inspection: Log in to the sub-router management interface regularly to check the network status, device connection status and system logs, and promptly identify and solve problems.

• Software upgrade: Pay attention to the firmware updates released by the manufacturer and upgrade in a timely manner to enhance the performance and security of the router.

• Performance monitoring: Utilize network management tools to monitor the usage of network bandwidth, optimize resource allocation, and ensure the smooth operation of critical business.

Correctly configuring the sub-routers of 4G/5G industrial wireless routers not only enhances the stability and efficiency of the entire industrial network but also effectively extends the lifespan of equipment and reduces maintenance costs. By following the above steps, you can easily master the setting skills of the sub-router and build an efficient, secure and stable network environment for your industrial applications. With the continuous maturation and popularization of 5G technology, future industrial wireless networks will be more intelligent and flexible, providing strong support for digital transformation. Let’s join hands and step into the new era of intelligent industry, creating boundless possibilities together.
