11 FAQ and Troubleshooting
1) My PC cannot connect to the CPE.

Re-plug the PC Ethernet cable and check if the PC LAN connection is up or showing activity.

Check if the PoE power adapter LED is on. If it is not, check the power cord and make sure it
is connected properly. Also verify that the AC power supply is available.

If the PC LAN shows no activity and PoE adapter LED is off but the power cord is connected
properly and there is AC supply, then it is likely the PoE adapter is damaged. Please contact
distributor to obtain replacement part.
2) My PC cannot acquire IP from the CPE.

First check if the PC NIC interface is up and working properly. Then check the PC NIC
configuration. If the device is running in router mode, then make sure the PC DHCP is
enabled. Open the MS-
DOS or CMD window, enter “ipconfig /release” and “ipconfig /renew”
commands and see if PC can obtain IP correctly.

If the device is configured to operate in bridge mode, the PC NIC IP should be manually
configured to be 10.1.1.X / 255.255.255.0 in order to gain access to the device WEB GUI.
When you are done with the device configuration, the PC NIC IP should be reconfigured to
use DHCP for proper LTE networking.

If the problem persists, please contact the operator or distributor for further diagnose.


You may want to check if the LTE connection is up and running properly. You can do this by

You may want to perform a factory reset and see if the problem is being corrected. You can do
this by log into the WEB GUI using the

If the problem cannot be corrected by factory reset, please contact the operator or distributor
for further diagnose.
