Hello ihealey,
Firmware and utilities can be found on the drivers and download page for your product. If you do not find what you're looking for, I suggest that you call into our support department for assistance @ 1-800-821-2797.
Is there a firmware update utility like there is for the WC6515?
I am running Mac Ventura and the browser is timing out on upload.
I can use the utility on Windows and it works. My only windows machine has been retired.
Thanks,
Ian
