1. Q: I entered the device's LAN IP address in the web browser but
cannot access the utility. What should I do?
Check whether device is functioning correctly. The Sys LED should blink a few
seconds after device is powered up. If it does not light up, then some internal
faults may have occurred.
Verify physical connectivity by checking whether a corresponding port's link
LED lights up. If not, try a different cable. Note that an illuminated light does NOT
ALWAYS indicate successful connectivity.
Run the "ping 192.168.0.1" command. If you get replies from 192.168.0.1,
open your browser and verify that Proxy server is disabled. In case that ping fails,
press and hold the "RESET" button on your device for 7 seconds to restore factory
default settings, and then run "ping192.168.0.1" again.
4) Contact our technical support for help if the problem still exists after you
tried all the above.
2. Q: What should I do if I forget the login password to my device?
A: Reset your device by pressing the Reset button for over 7 seconds. Note:
All settings will be deleted and restored to factory defaults once you pressed the
Reset button.
3. Q: My computer shows an IP address conflict error after having
connected to the device. What should I do?
A: 1) Check if there are other DHCP servers present in your LAN. If there are
other DHCP servers except your router, disable them immediately. 2) The default
IP address of the device is 192.168.0.1; make sure this address is not used by
another PC or device. In case that two computers or devices share the same IP
addresses, change either to a different address.
4. Q: I cannot access Internet and send/receive emails; what should I
do?
This problem mainly happens to users who use the PPPoE or Dynamic IP
Internet connection type. You need to change the MTU size (1492 by default). In
this case, go to "WAN Settings" to change the MTU value from default 1480 to
1450 or 1400, etc.
5. Q: How do I share resources on my computer with users on Internet
through the device?
A: To let Internet users access internal servers on your LAN such as e-mail
server, Web, FTP, via the device, use the "Virtual Server" feature. To do so, follow
steps below:
Step 1: Create your internal server, make sure the LAN users can access
these servers and you need to know related service ports, for example, port for
