Troubleshooting
1.
How do I configure my TW-EAV510 Router without the CD-ROM?
Connect your PC to the Router using an Ethernet cable.
Open a web browser and enter the address
The default username is ‘admin’ and the default password is ‘admin’.
If you have changed the password and cannot remember it, you will need to reset the
Router to the factory default setting (see question 2), which will set the password back to
‘admin’.
Note:
Please refer to the next section “Networking Basics” to check your PC’s IP configuration if
you can’t see the login windows.
2.
How do I reset my Router to the factory default settings?
Ensure the Router is powered on.
Press and hold the reset button on the back of the device for approximately 10 seconds.
This process should take around 30~60 seconds.
3.
What can I do if my Router is not working correctly?
There are a few quick steps you can take to try and resolve any issues:
Follow the directions in Question 2 to reset the Router.
Check that all the cables are firmly connected at both ends.
Check the LEDs on the front of the Router. The Power indicator should be on, the Status
indicator should flash, and the DSL and LAN indicators should be on as well.
Please ensure that the settings in the Web-based configuration manager, e.g. ISP
username and password, are the same as the settings that have been provided by your ISP.
4.
Why can’t I get an Internet connection?
For xDSL ISP users, please contact your ISP to make sure the service has been
enabled/connected by your ISP and that your ISP username and password are correct.
5. What can I do if my router can’t be detected by running installation CD?
Ensure the Router is powered on.
Check that all the cables are firmly connected at both ends and all LEDs work correctly.
Ensure only one network interface card on your PC is activated.
