To log into your X-Micro router, open a web browser and enter the default IP address, such as 192.168.1.1, into the address bar. Press Enter, and a login page should appear. Use the default username 'admin' and password 'admin' to access the settings. If that doesn't work, try other common credentials like admin/password or root/root. Once logged in, it's crucial to change the default password to enhance security. Navigate to the administration or system settings to update your credentials and customize your network. Always ensure your router firmware is up to date for optimal performance.
