If you found the router is working improperly or stop responding to you, don't panic! Before you contact your
dealer of purchase for help, please read this troubleshooting first. Some problems can be solved by you within
very short time!
Router is not responding when attempting 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 out, please check the status of A/C power adapter, and make sure it's
correctly powered.
c. You must use the same IP address section which router uses.
d. Are you using MAC or IP address filter? Try to connect the router by another computer and see if it works;
if not, please perform a hard reset (press and hold 'reset' button for 20 seconds).
e. Set your computer to obtain an IP address automatically (DHCP), and see if your computer can get an IP
address.
f. If you did a firmware upgrade and this happens, contact your dealer of purchase for help.
g. If all above solutions don't work, contact the dealer of purchase for help.
Can't get connected to Internet
a. Go to 'Status' -> 'Internet Connection' menu, and check Internet connection status.
b. Please be patient, sometime Internet is just that slow.
c. If you connect a computer to Internet directly before, try to do that again, and check if you can get
connected to Internet with your computer directly attached to the comm. device provided by your Internet
service provider.
d. Check PPPoE / L2TP / PPTP user ID and password again.
e. Call your Internet service provide and check if there's something wrong with their service.
f. If you just can't connect to one or more website, but you can still use other internet services, please
check URL/Keyword filter.
g. Try to reset the router and try again later.
h. Reset the comm. device provided by your Internet service provider too.
i. Try to use IP address instead of hostname. If you can use IP address to communicate with a remote
server, but can't use hostname, please check DNS setting.
I can't locate my router by my wireless client
a. 'Broadcast ESSID' set to off?
b. All three antennas are properly installed and secured?
c. Are you too far from your router? Try to get closer.
d. Please remember that you have to input ESSID on your wireless client manually, if ESSID broadcast is
disabled.
e. If antenna is not installed, install them now and never remove them.
