The LTE modem integrated into DrayTek LTE routers ("L" suffix) can connect
directly to a mobile broadband network and operate as either a main internet
connection or a backup internet connection. The modem is integrated into
the router instead of using a separate USB modem and requires a SIM card to
connect to the mobile broadband network required.
The settings for the mobile broadband network will vary by provider, some
will require the APN (Access Point Name) while others may require that and a
username and password. If those details are not set, the mobile network may
reject the connection attempts of the Vigor LTE router, which will result in
the router showing no signal / no IP address.
To configure the LTE WAN interface on the router, it is first necessary to fit
the SIM card in the router, refer to section 3.2 for details of SIM card and
antenna installation.
After the SIM card has been installed, power on the router, access the router's
web interface and go to [WAN] > [General Setup] to confirm the LTE WAN
options, by clicking the LTE link:
In the LTE General Setup options, ensure that the connection is Enabled and
set the Active Mode as required.
If the internet connection should always be available, set it to Always On:
