Appendix 3 Faqs - Tenda FH305 User Manual

This section provides solutions to problems that may occur during installation and operation of the device. Read the following if you are running
into problems. If your problem is not covered here, please feel free to go to www.tendacn.com to find a solution or email your problems to:
support@tenda.com.cn or support02@tenda.com.cn. We will be more than happy to help you out as soon as possible.
1. Q: I entered the device's LAN IP address in the web browser but cannot access the utility. What should I do?
a.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.
b.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.
c. 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.
d. 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?
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.Check if there are other DHCP servers present in your LAN. If there are other DHCP servers except your router, disable them
immediately.
b.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?
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 number for Web server is 80; FTP is 21; SMTP is 25 and POP3 is 110.
Step 2: Enter Port Forwarding (also called Port Range Forwarding on some products) screen from device web UI.
Step 3: Complete the Start Port (also called External/Ext Port on some products) and End Port (also known as Internal Port on some products)
fields, say, 80-80.
Step 4: Input the internal server's IP address. For example, assuming that your Web server's IP address is 192.168. 0.10, then simply input it.
Step 5: Select a proper protocol type: TCP, UDP, or Both depending on which protocol(s) your internal host is using.
Step 6: Click Enable and save your settings.
For your reference, we collected a list of some well-known service ports as follows:
