Win7 mac authentication failure



We have a couple of AP running and they have configured MAC authentication with internal server authentication ( blacklist disable, uppercase support disable). The issue is when a new machine tried to authenticate I got a radius authentication failure on the logs, this happend with win7 or some win10 machines, is there a specific setting on the machines that might need in order to connect to the aruba wireless?


We have WPA2-Personal on the Aruba AP and currently using around 28 users. All of them are registered on the Security settings MAC address with Uppercase  and  delimite character -  , the profile is employee we only have  1 SSID,.

MAC-authentication does not involve the client at all. Are the new devices
added to the internal database?

Hi Tim,


The new machines are added to the database, eventhough the are in the DB , I am still getting radius authentication failure (win7 or win10) . If I disable the mac authentication and use WPA2-Personal with no MAC authentication the machines are able to use the wireless network. We have disabled antiviruses , firewalls on the machines.

I found something odd on the configuration:

the lenght of the password is different for those 2, in the case of the long lenght the MAC authenticatio is working  while the other it is not.
