Troubleshooting
Check below for solutions to common problems you may experience.
Problem: My device is unable to connect to the 5G Gateway Wi-Fi network.
Solution: Check to make sure Wi-Fi is enabled on your device and the Wi-Fi
LED is solid green on the 5G Gateway. If the LED is red, you may need to
power off and on your gateway. You may also check to see if the device is on
the Blocked Devices List.
Problem: A web page is loading slowly or won’t load at all.
Solution: Check the signal strength using the 4G and 5G LED indicators.
When the device is not receiving a cellular signal, no LED lights will display.
Connecting an external antenna or repositioning your gateway to an area
with better cellular coverage may improve your experience.
Problem: I forgot my Wi-Fi password.
Solution: You can retrieve the Wi-Fi password by logging into the Web UI
and navigating to the Wi-Fi settings from a connected device. You can also
connect using Ethernet without a password.
Problem: I forgot my Web UI admin password.
Solution: If you haven’t changed the password from the default, it can be
found on the label at the bottom of the gateway. You can also complete a
factory reset to reconfigure the password back to the default, see “Reset to
Default” on page 46.
