I've tried downloading the 15.3.1 driver, but that appears to not be an actual driver - it looks like it's a newer version of the Wireless ProSet application; regardless, I end up with the same driver version 13.4.0.139 dated 7OCT10 installed on the machine when I download it and install that file. Any further advice on this front would be appreciated.
I'll look into the FIPS situation and see if that helps.
Best Regards,
Rob
