Analysis and solutions for common faults of cpe 4g lte

With popularity progress of wireless networks, more and more people use wireless devices and various faults increased also. Various wireless network faults are often encountered in process of wireless Internet access, these Network failure has seriously affected normal Internet efficiency. How to solve cpe 4g lte failure quickly?

1.Why the cpe 4g lte’s power light flashing?

1.1.Power adapter or outlet problem: cpe 4g lte’s power adapter or outlet might be faulty, causing other lights to turn off. You can try to change the power adapter or power socket to see if can fix the problem or not.

1.2.Internal hardware failure: If hardware failure inside cpe 4g lte, such as motherboard or chipset failure, it may also cause only the power light to be on. In this case, it is recommended to send cpe 4g lte to after-sales service center for inspection and repair.

1.3.Poor contact of network cable: If network cable port of cpe 4g lte has poor contact, it may also cause other indicators to not light up. You can try to unplug network cable then plug it in again, or check whether there is a problem with the crystal head.

1.4.Setting problems: Sometimes there may be problems with cpe 4g lte settings such as incorrect IP address etc., this may also result in only the power light being on. You can try to put cpe 4g lte’s IP address into your browser to restore to default settings.

1.5.CPE 4g lte damage: If cpe 4g lte is physically damaged, it may also cause only power light to be on. In this case, it may be necessary to replace it with a new one.

2.Why cpe 4g lte access was restricted?

2.1.The device cannot obtain enough network access: If wrong account or password is entered, access may be restricted.

2.2.CPE 4g lte and devices may experience glitches or temporary issues: a reboot can clear these issues and get back to normal status.

2.3.CPE 4g lte has an access control list (ACL) set up: it may cause some devices unable to connect or access the network, you can try to modify ACL configuration in the cpe 4g lte management interface.

2.4.The device does not support the security protocol of the WiFi network: access may be restricted. You can try to update the device driver or firmware, or connect to the WiFi network with another supported security protocol.

2.5.The wireless function of cpe 4g lte is not turned on: Please check whether the wireless function of the cpe 4g lte is turned on or not.

2.6.Computer IP is not set to be automatically obtained.

3.When cpe 4g lte cannot enter configuration page, check default IP of cpe 4g lte has changed or not, use changed IP to enter the page if it has changed.

4.After running normally for some time and is disconnected and unable to reconnect to the network, check whether SIM card is in arrears and is “Stay Online” configured in cpe 4g lte configuration page?

5.When cpe 4g lte often goes offline, check the debugging information, keeponline timeout is the online timeout.

6.If you forget the cpe 4g lte IP after changing it, or you cannot log into the web page after changing the configuration, you can open serial port debugging tool, open serial port and connect Ethernet to serial port cable to Console port, hold down Ctrl+C at the same time to power on the device, and run it after entering Run restore, after run prompts OK, you can quickly restore factory configuration. Note that after OK, close serial port tool and restart the device, log into the page again to reset. Open serial port debugging tool and refresh program version.

7.When number cannot be dialed, check whether username and password correct and re-enter, meanwhile check the system debugging. If cpe 4g lte is in arrears, it will be directly connected to the contact center’s webpage; if  private network cannot dial the number, try to use ordinary network first, the private network card has problem if ordinary network can dial the number.

8.CPE 4g lte and analog cameras are used in video surveillance. Network cameras are required to be used in video surveillance projects with cpe 4g lte. Whether the video transmission is smooth is closely related to the code stream of the front-end device, the code stream refers to the amount of data in seconds for each video.

9.We are unable to log in and unable to log in the background management interface of cpe 4g lte from time to time, there are many reasons. We should start with the connection status of the cpe 4g lte first to check the device to see whether there is hardware failure, normally we can quickly determine whether there is a hardware failure in the device by observing the signal light in the control panel of the cpe 4g lte.

9.1.After confirming connection status of cpe 4g lte is normal, we can enter LAN workstation system and check network connection currently used to see whether the IP address used is dynamic or static. If dynamic address was used, we can try to change it to static IP address, meanwhile turn off the network firewall function of the local system.

9.2.After above efforts, if we still cannot log in to cpe 4g lte, we can try to modify IE settings. When modify IE settings, you can first open IE browser window and execute Tools-Internet Options in the menu bar of the window. In the Internet Options Settings window that pops up, click “Connection” tab and select “Never dial-up connections” in corresponding tab page, then click “LAN Settings” button in the tab page and select Clear all options in subsequent settings page, and finally click “OK” button to end IE setting operation.
