1. Can not log in to the Web-based Utility of the router after you enter the IP address in the
address field?
Step 1: Check if the router is working correctly, after the device is powered on for a few
seconds, the SYS indicator on the front panel should light up. If it is not, please contact us.
Step 2: Check the network cables are connected correctly and the corresponding LED
indicator lights up. Sometimes, the indicator lights up, but it does not mean it is functioning.
Step 3: Run “Ping” command and check if it can ping the Router’s LAN IP address
192.168.0.1 (open “Command Prompt” and type “Ping 192.168.0.1” and then enter). If it is
OK, please make sure your browser does not access the Internet by proxy server. If the
ping fails, you can press the “RESET” button for 7 seconds to restore to default settings.
And then repeat the ping operation. If it still does not work, please contact us.

do?

do?
Check if there are other DHCP servers in the LAN and if there are then disable them. The
default IP address of the router is 192.168.0.1 please maker sure the address is not being
used by any other device. If there are two computers with the same IP address, please
change one of them.
4. I cannot use E-mail and access the Internet. What can I do?
Sometimes happens with ADSL connection and Dynamic IP users. You may need to modify
the default MTU value (1492). Please open the “WAN Setting” and modify the MTU value
with the recommended value as 1450 or 1400.
