When I look at my list of clients most of my Windows machines are tagged as Windows Mobile and a few as Windows 10. Similarly most of IOS devices are listed just as iPhone and a few are more accurately shown. Is there anyway to get it to be more accurate?
Could you confirm on what version your ZD is? And what ZD model?
Make sure ZD is on recommended version. If still facing issue, try to upgrade to latest version (before that check and make sure your AP models supports latest version).
It is a ZD1200 running 10.4.1.0 build 238 which I think is the latest version. Honestly the device fingerprinting has been horrible for ever. I just noticed it finally started to get more accurate but is only doing it for some devices. It also detects all of our Wi-Fi thermostats as Xbox 360?
