LTE6100 User’s Guide

If the problem continues, contact the network administrator or vendor, or try one of the advanced 
suggestions.

• Try to access the LTE Device using another service, such as Telnet. If you can access the LTE 

Device, check the remote management settings and firewall rules to find out why the LTE Device 
does not respond to HTTP. 

• If your computer is connected to the WAN port or is connected wirelessly, use a computer that is 

connected to a ETHERNET port.

I can see the Login screen, but I cannot log in to the LTE Device.

Make sure you have entered the user name and password correctly. The default user name is 
admin. These fields are case-sensitive, so make sure [Caps Lock] is not on. 

You cannot log in to the web configurator while someone is using Telnet to access the LTE Device. 
Log out of the LTE Device in the other session, or ask the person who is logged in to log out. 

Turn the LTE Device off and on. 

If this does not work, you have to reset the device to its factory defaults. See

Make sure you entered your service provider’s LTE APN information correctly.

Disconnect all the cables from your device, and follow the directions in the Quick Start Guide again. 

If the problem continues, contact your ISP.
