This is nice because by saving the configuration, altering the file and uploading it again, you can change settings not exposed in the interface.<br> For example, on my <a href="https://www.dlink.com/uk/en/products/dsl-2640b-adsl-2-wireless-g-router-with-4-port-10-100-switch">D-Link DSL-2640B</a> I could disable a broken QoS which was slowing down the download speed just by setting <code>X_BROADCOM_COM_ATMEnbQos</code> to FALSE.</p> <p>When I got a TP-Link wireless access point, I tried the same trick but found that they had started encrypting the configuration file, making it impossible to edit manually.</p>
