In an era when network information is so advanced, the Internet has become inseparable in people's lives. Today, routers are not only satisfied with people's lives, but they are also widely used in industry. The following are some common troubleshooting methods for industrial 4G routers.
1, 4G router can not enter the configuration page?
A: The default IP of the 4G router is changed. If it changes, please use the changed IP to enter the page.
2, 4G router normal (Online lights). But can't ping the network?
Whether the PC's gateway points to the 4G routed IP (4G router factory IP: 192.168.1.2).
The PC's DNS server IP address is filled.
3, 4G router normal operation for some time, the broken line can not re-board the network first?
Check if the SIM card owes money.
On the 4G router configuration page, "Online hold" is configured.
4, the device is often dropped reasons?
A: Check the debug information, keeponlietimeout is online to maintain timeout.
5, 4G router IP is forgotten to change, or how to deal with the page after the configuration change can not be handled?
Open the serial port debugging tool, open the serial port, Ethernet to serial line connection Console port, hold the Ctrl + C while the device is powered on, run into the runrestore, run prompts to complete the OK can quickly restore the factory configuration, pay attention to close the serial port tool after OK , and then restart the device, you can re-login to reset the page.
Open the serial debugging tool and refresh the program version.
6, why not dial the number?
Check if the username and password are wrong, and re-enter it;
Check the system commissioning, the status of card arrears will always negotiate PPTP, check card arrears available instructions: AT + Creg or AT + cgatt;
Onlie flashes that the number is dialed, not even the center;
4G router arrears will be directly connected to the contact center's website;
Special network can not dial the number can be used to try the ordinary network, if the ordinary network can dial is the problem of a special network card.
Can 7 and 4G routers be compatible with analog cameras for video surveillance?
A: Network cameras are required to be used in conjunction with our 4G routers for video surveillance projects. The smoothness of the picture for transmitting video is closely related to the bit stream of the front-end device. The bitstream refers to the amount of data per second of the video. 8 Telecom's 3G4G Routing Internet is also a public network dynamic IP Now our 4G router built-in peanut shell customers can directly in the 4G router settings for domain name resolution, it also needs to do port mapping?
A: Just fill in ROUTER's dynamic domain name resolution with the username and password of the peanut shell.
9. Is the IP address obtained using a telecommunication CDMA network a global IP address?
A: At present, but some places have closed the port.
10, VPN dial-up side, after the default 4G routing is closed, it can be on the external network?
A: Because the default 4G route can only be used to access the dial-up server, there is a problem. I want to make the device below 4G available on the public network after the VPN dial-up state. 11. The M company has data collection outdoors. Devices A and A have their own IP address. After connecting to the 3G4G router B, they access the mobile APN node through the B. The collected data is transmitted to the M company's network center through the mobile network. The network center processes the data after obtaining the data. In such a scenario, how should B set (transparent settings)?
A: If A is a private IP that can be connected via Ethernet to our 4G router, our 4G router has APN settings. Fill in your APN account and password to the corresponding address. Our 4G router will pick up the card. Power on the line.
I hope that the above simple and common troubleshooting methods will help you!
