Firmware for the WAG120N, a Linksys ADSL2+ wireless gateway, version 1.7, in a 3.47 MB RAR archive. The name gives only the model and version, so check whether it is a full flash dump or an upgrade file before use. Full dumps are written to the flash chip with a programmer to recover bricked units, while upgrade images go through the web interface or recovery mode. Back up the original flash first, as it stores MAC and configuration data, and confirm the hardware version of your unit is compatible.
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.
