Firmware image for the TP-LINK WR842N wireless router, hardware version 4.4, labelled as fully working and packed in a RAR file. A dump like this is the usual remedy for a bricked router whose bootloader or firmware region is corrupted, and is programmed directly into the SPI chip. Confirm that your unit is version 4.4 by its rear label, verify the chip size matches the image, and back up the existing contents first, since the factory radio calibration and MAC address must be preserved for Wi-Fi to work properly.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
