5 common reasons why 4G industrial routers are not connected to the Internet

zoko-link has sorted out the top 5 reasons why users can't connect to the Internet with 4G industrial routers, which are as follows:

①SIM card problem

Although 4G industrial routers have networking functions, they mainly rely on the cellular network of the SIM card for networking. 4G industrial routers can be connected to the Internet and are completely dependent on cellular networks.

See if the SIM card supports 4G. If it does not, the network connection cannot be opened and the 4G industrial router cannot be connected to the network.

If the SIM card's traffic is exhausted, the surrounding space is too limited and the signal is too poor, the software level is not updated in time, resulting in no service or identification failure, etc., will become the culprit for not connecting to the Internet.

②Antenna problem

Check if there is a problem with the antenna. Because the antenna is a good helper for enhancing the signal of 4G industrial routers (the more antennas the greater the power, the maximum is only about 150M).

So once there is a problem with the antenna, the signal penetration of the 4G industrial router will be very weak, the power of the 4G industrial router will be greatly reduced, and the most serious thing is that it will not connect to the Internet.

So be sure to check carefully whether there is a problem with the antenna.

③Operator frequency band problem

When purchasing a 4G industrial router, be sure to ask the relevant operators that support it. Some manufacturers’ products do not support full Netcom, which results in users not being able to access the Internet.

For example, if a user purchases a 5 mode 12-band 4G industrial router, they cannot use Telecom's 2G network and 3G network, which leads to the embarrassment of not being able to connect to the network.

So before buying, you must ask customer service whether it supports major operators and whether it is full Netcom.

④Firmware version problem

The 4G industrial router will be used with the firmware version. If your solid-state hardware is not updated for a long time, it will also cause the function not to be fully supported, which will lead to the situation of not connecting to the Internet.

⑤Reset router problem

Under normal conditions, after the user installs the industrial router on the SIM card according to the requirements, follow the instructions to connect various manual related interfaces according to the instructions, then open the browser, click and log in to the setting webpage to complete the simple modification and setting of the parameters. You can go online.

If you can’t connect to the Internet after checking the previous items carefully, you have to restore the factory settings to connect to the Internet.

The specific method of restoring the factory settings: Press and hold the Reload button with a pin for 3-15 seconds to restore the factory settings of the 4G industrial router.

Summary: The above is an analysis of the top 5 common reasons why 4G industrial routers are not connected to the Internet, and a brief description.
