Firmware archive labelled only 8951, which points to a TP-Link TD-W8951 family ADSL router, although the name gives no hardware version or build date. The 1.28 MB zip should be opened to see whether it holds an upgrade file or a full flash dump. Because TP-Link firmware is tied to hardware revision, compare the contents with the version on the device label before flashing. For bricked units programmed directly, read and keep the original chip first so the MAC address and radio settings are not lost.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
