for help, please read this troubleshooting first. Some problems can be solved by you within very short time!
Scenario Solution
Router is not responding to
me when I want to access it
by web browser
a. Please check the connection of power cord and network cable of this router. All cords
and cables should be correctly and firmly inserted to the router.
b. If all LEDs on this router are off, please check the status of A/C power adapter, and make
sure it’s correctly powered.

computer can get an IP address.
