Firmware archive for a TP-Link 8811 series ADSL modem, version 2.3, most likely the TD-8811, though the name gives only the number. No flash chip is specified, so read the marking on the chip and compare its capacity with the unpacked image before writing. Technicians use such dumps to restore a bricked modem through direct SPI programming. Back up the original chip first, since it contains the unit's own MAC and configuration area, and confirm the hardware version printed on the case.
