In some bad environment, it is easy to have the network connection disconnection connection connection. The industrial 4G router’s on line probe regularly checks the network connection status, reconnects if something goes wrong, and restarts the device after a period of trying, if it still doesn’t work, to get the network online.
The online detection parameters for an industrial 4G router have the following meanings:
1. Probe type: currently supports Ping/Traceroute/DNS three types of probe.
2. Ping: Ping Will Ping an IP or domain name, and Ping denies being online
3. Traceroute: Traceroute tracks the path of an industrial 4G router and thinks it’s online if it can get to its destination address
4. DNS: DNS resolves a domain name, if it can, then it’s online; the default industrial 4G router uses ping, and using traceroute is relatively fluid, and DNS resolution is faster, but because DNS has a cache, you’re still online when you’re offline. The relative use of ping makes the most sense.
5. Industrial Router Master Probe Server: The Priority Probe server can be IP or domain name
6. Secondary probe server: if the primary probe server fails, the secondary probe server can be selected.
7. Number of retries: if the probe fails, you can specify the number of retries for the industrial router
8. Retry interval: the time interval between probes
Enable restart: if the Industrial 4G router has not been online, click “Open”, will restart after a specified time
10. Failed Probe restart time: specify how long to be offline and restart the device
