If the problem persists, refer to Q3 to reset the router and try
again.
Q3: How to reset the router?
A3: When the device completes startup, press the WPS/RST
button for about 8 seconds, and release it when all LED
indicators light off and then light up. The router will be reset
successfully in about two minutes.
Q4: How do I access the internet through the SIM card
or(and) WAN port?
A4: Insert a SIM card (if any), connect the WAN/LAN port to the
internet using an Ethernet cable, enable the Failover
function and configure internet parameters on the Internet
Settings page.
Tips
• When you access the internet through the SIM card and WAN port, the WAN
port is prioritized for internet access by default. You can manually switch the
SIM card or WAN port to the current internet connection mode on the
Internet Status page as required.
• If there is a network failure, the router will automatically switch to an available
internet connection mode.
