any advices is greatly appreciated. :-)

FAT uses firmadyne which internally uses binwalk.

The error message you are getting is due to extractor.py component of firmadyne failing. Can you run just binwalk to check if this is indeed the case.

binwalk -e <firmware file>

Alternatively, you can run extractor.py as below.

./sources/extractor/extractor.py -b Netgear -sql 127.0.0.1 -np -nk "WNAP320 Firmware Version 2.0.3.zip" images

Closing. If your issue persists, feel free to reopen.

Good afternoon,

I experience the same error. I am able to run your extractor.py command but get this warning when running binwalk

WARNING: Extractor.execute failed to run external extractor 'jar xvf '%e'': [Errno 2] No such file or directory, 'jar xvf '%e'' might not be installed correctly
