Firmware package for the TP-LINK TD-W8950 ADSL modem router, hardware version 1.1, intended for an 8 MB flash chip according to the name. The 5.83 MB RAR archive likely contains a full flash image used to recover a unit that no longer boots after a failed update or corrupted configuration. Recovery usually means writing the image to the SPI flash with a programmer or via a bootloader method. Check the hardware version on the label underneath the router, dump and save the original chip first, and make sure the image size matches the flash capacity.
