Appendix B FAQ

Q1. What can I do if I cannot access the web-based configuration page?

1. For the first login, please try the following steps:

1) Make sure the cable is well connected to the LAN port of the Router. The corresponding LED

should flash or be solid light.

2) Make sure the IP address of your PC is set in the same subnet addresses of the Router. It’s

recommended to set your PC to get the IP address automatically. Then the Router with DHCP

enabled can automatically assign the IP address to your PC. If you want to configure your PC

manually, please set 192.168.0.x ("x" is any number between 2 to 254) for the IP address and

255.255.255.0 for the Subnet Mask.

3) Test the connection between your PC and TL-ER5120 via Ping command.

4) If you still cannot access the configuration page, please restore your Router to its factory

default settings and try to log in again.

2. If your management port has been changed, please log into the Router with the new address,

such as http://192.168.0.1:XX

(“XX” is the new management port number).

3. If you had successfully logged into the Router before, but now you cannot access the Router. It’s

quite possible that the configuration of your Router has been changed by others, especially when

the Remote Web Management function is enabled. You’re recommended to restore your Router

and reconfigure the management port number and the username as well as the password for your

network security.

4. If you cannot access the Router even after restoring the Router to its defaults, or your login is

dropped down just after a while, it’s quite possible that your Router is attacked by ARP cheating.

It’s recommended to locate and quarantine the source of ARP cheating so as to prevent your

network from the attacks.

5. Check to see if you have configured the proxy server for IE browser. If so, please disable the IE

proxy server first.

Q2: What can I do if I forgot the username and the password of the Router? How to restore the

Router to its factory default settings?

You can restore the Router to its factory default settings by the Reset button. It must be noted that

once the Router is reset, all the current configuration settings will be lost.

With the Router powered on, use a pin to press and hold the Reset button for about 5~10 seconds.

After the M1 LED is solid light for 2~5 seconds, release the Reset button. When the M1 and M2 LEDs

flash simultaneously for about one second, the Router is restored successfully. The default

management address of the Router is http://192.168.0.1, and the default username and the password

are both admin.
