To access the TP-LINK repeater login, connect to its Wi-Fi network, open a web browser, and enter the default IP address (typically 192.168.0.254) in the address bar. Log in with the default username and password (usually admin/admin). Once logged in, you can configure and manage the repeater's settings, including Wi-Fi network names, security settings, and more. It's crucial to change the default login credentials for security. Refer to the device's manual for specific login details, as they can vary between models. For further assistance, contact us.
