Authenticated guests on guest wifi randomly disconnected when MAC filter activated

Hello,

 

We have an issue with our guest SSID on Aruba Instant AP 205.

 

The guest wifi is configured to use both MAC authetification and username/password.

 

The problem is that guests who authenticate with username/password get disconnected after random time (and not the one setted up into the configuration) and have to reconnect.

After some tests we noticed that there is no disconnection when we disable the MAC authentification (but we need it...). We believe that the AP check the MAC adress for time to time and disconnect the user if the MAC is not authorized...

 

Any idea on how to resolve this issue?

 

Thank you,

 

Cyril

You should look in the access tracker to see if there is any activity on that client...

Thank you for your reply.

 

Is the access tracker available on the AP205 ? We are not using a physical controller or clearpass.

I apologize.

 

Is this a controller-based deployment?  Are you turning on the mac filter by enabling mac authentication?  What is your mac authentication configuration?

We have configured a virtual controller. 

Yes we have enabled the MAC authenthication on the security tab of the guest wifi configuration setup (see attached picture). 

 

Let me know if you need more information.

 

Thank you for your help,

According to that picture, guests are forced to reauthenticate after 24 hours.  That should not be triggered unlesss your guests are connected for 24 hours straight.  I would set the reauthentication interval to 0 and see if it continues to happen.

Thanks,

Re: Authenticated guests on guest wifi randomly disconnected when MAC filter activated

Mac authentication should not allow a user to connect if their mac address is not in the list.  It should not disconnect them after that.

 

When you say disconnect, what you do mean?  What happens?  Does the user lose their ip address?

 

What kind of authentication are you using besides mac authentication on this SSID?
