To test your ADSL line, start by checking the modem/router’s status lights to ensure it's properly connected and synchronized. Next, perform a speed test using a reliable online tool to check the internet speed. If you encounter issues, try resetting your modem/router and retesting. For a more thorough inspection, access your modem/router’s interface to view line statistics such as signal-to-noise ratio (SNR) and line attenuation. Persistent issues may require contacting your ISP for a line check or further technical support.
