TROUBLESHOOTING

How do I reset the router to the factory default settings?
You can restore the factory default settings via the hardware RESET button located on
the back panel of the router. Use a small paperclip to activate the button; insert it into
the hole (with the device turned on), push, and hold for 10 seconds. Release the button
and wait until the router is rebooted (about a minute or two). Then access the webbased
interface (see the Default Settings section of the present document) and
configure all needed settings.

What can I do if my router is not working correctly?
Below are some steps applicable to the most common issues.
1. Check the LEDs on the top panel of the router. The POWER and INTERNET
LEDs should be solid white; the 2.4G WLAN and 5G WLAN LEDs should be
solid or blinking white (if the 2.4GHz or 5GHz wireless network
correspondingly is on and in use).
2. Make sure that all cables are connected properly.
3. Power off the router for 20 seconds, then power it on again.

Why am I unable to connect to the Internet?
Contact your ISP to make sure that the relevant service is available and that you use
correct connection settings.
