Firmware for a TP-Link TD-8901N ADSL router, hardware version 2, in a four-port variant according to the name, packed as a 1.33 MB RAR archive. Router firmware must match the exact hardware version printed on the sticker under the unit, otherwise the device can be bricked. Such files are used either through the web interface upgrade page or, for dead units, by writing the flash chip directly with a programmer or via serial console. Keep a backup of the original flash, since it may contain calibration and MAC address data.</div>
