In the industrial field, industrial 3G/4G wireless routers undertake key data transmission tasks, and when the network has problems or needs to be maintained, restarting the router is often one of the effective ways to solve the problem. Here is a detailed description of how to restart this type of router.
Why restart an industrial 3G/4G wireless router
Industrial 3G/4G wireless routers may experience cache accumulation, connection interruption, and slow network speed after a long period of operation. This may be due to electromagnetic interference in an industrial environment, the use of system resources caused by large amounts of data transmission, or network signal fluctuations. Restarting the router can clear the cache, re-establish the network connection, and restore the router to the best working state, thus ensuring the stable operation of the industrial network.
Preparations before the restart
Back up the configuration file: Log in to the management interface of the router, find the configuration file backup option, and download and save the current router configuration file to the local PC. In this way, if the configuration is lost after the restart, it can be quickly restored.
Record important information, including the login account and password of the router, configured network parameters (such as IP address, subnet mask, gateway, and DNS server), and connected device information.
Restart method
Hardware restart
Find the power interface: Industrial-grade 3G/4G wireless routers usually have a dedicated power interface, which may be a DC power interface or a cable power supply (PoE) interface.
Power off: Remove the power adapter from the router, or power off the corresponding port on the PoE switch when the PoE is powered. If the router is using battery power, remove the battery.
Wait a moment: It is recommended to wait 3-5 minutes for the capacitors inside the router to discharge, ensuring that all circuits stop working completely.
Reconnect the power supply: reinsert the power adapter to the router, or reinstall the battery, and power on the PoE switch port. Observe the router's indicators, usually the power indicator will light up first, and then other indicators will blink or steady on in a certain order, which means that the router is starting. If the indicator status is stable, the router is restarted.
Software restart
Log in to the management page: Open the browser, enter the management IP address of the router in the address box. On the login page that is displayed, enter the correct user name and password.
Find the Restart option: In the router's administration interface, you can usually find buttons for similar functions such as "Restart router" or "System Restart" in menu options such as "System Settings", "Device Management" or "Tools".
Confirm the restart: After clicking the Restart Router button, the system may display a confirmation dialog box, indicating that the restart operation may cause network interruption. Click the OK button, and the router will automatically restart.4G industrial router
Check and set after restart
Check the indicator status: Check whether the power indicator, network connection indicator (such as WAN port indicator, LAN port indicator), and 3G/4G wireless router signal indicator are on. If any indicator is abnormal, it may indicate that the router is faulty or has a connection problem.
Log in to the management page to check configurations: Log in to the management page of the router again and check whether network configurations, such as the IP address, subnet mask, gateway, and DNS server, are correct. If necessary, you can upload the backup configuration file for restoration.
Test network connection: Using industrial equipment or computers connected to the router, try to access the Internet or other devices in the industrial network to check whether the network is properly connected and whether the data transmission is stable.
In short, mastering the correct industrial 3G/4G industrial router restart method is crucial to ensure the stable operation of industrial networks. During the restart, strictly follow the steps to avoid device damage or data loss due to improper operations. By restarting routers regularly or on demand, network problems can be effectively solved and the efficiency and reliability of industrial production can be improved.
