What should I do if I can’t log into web-based interface of my TP-Link device?
For most TP-Link products, a web-based interface is the only way to configure the product. Chances are that you cannot log in to its interface at the initial setup or after the configuration even though you can access the internet.
Refer to Quick Installation Guide to check the physical connection between your end-device and the TP-Link if you are using an Ethernet connection to visit the interface of TP-Link. If the LAN/Ethernet LED is not lit with Ethernet cable from the end-device plugged in the TP-Link, try different Ethernet ports and cables.
Log in to the Web-based Interface through the default domain name or default IP Address, which can be found on the installation guide. Make sure you type the domain name or IP address in the address bar instead of the search bar.
If you can access TP-Link login address correctly using the domain name or IP address, but fail to log in using login username and password. The default username and password are both admin in lower case. However, if the default credential cannot work, reset the TP-Link device into default settings by pressing the reset button for 10s if you have forgotten the customized username and password. Or you can refer: What can I do if I forget the login password of TP-Link Wireless Router?
Restart the TP-Link device. A simple restart by pushing the power off and on the button will not bring any harm.
Note: If there is no internet at all, or if you don’t mind losing all your configuration, please reset the device. Usually, there is a reset button/hole on the TP-Link device, push it for a few seconds can factory reset it.
Simplify network topology by connecting only one end-device to the TP-Link device. DO NOT connect any other devices like modem or server because those may have an impact on the running of web-based management server of the TP-Link or your end-device.
If it’s a wireless router, disconnect the modem from the router; if it’s a range extender, connect one end-device to it via wireless.
If a problem still exists,
a. Try different web browsers and end-devices. If you only have one end-device, like a computer, attempt to restart the computer or clear DNS cache on the computer (click here).
b. Check the IP address and Default Gateway obtained on the end-device (click here). Please write them down. Use the default gateway address to log in if you have changed the IP address of the TP-Link device.
c. Disable firewall or antivirus software.
Please contact TP-Link support and provide the IP address and Default Gateway that you’ve found.
Note: End-device means laptops, smartphones, etc.
