Random Wrong password after connect to another AP

This is my environment, two controller 7240 and many ap 135.

When i move from one floor to another i lose connection, and receive error in authentication, wrong password on my samsung gt-s6310n. The data traffic is tunneled to the controller.

 

this the capture log:

Re: Random Wrong password after connect to another AP

Yes.  You need to look to see if your radius server is overloaded, or is not answering for some reason..

 

"show aaa authentication-server radius statistics" will let you know if you have a problem.

Re: Random Wrong password after connect to another AP

According to that output, you have had 452503 timeouts to that radius server.  You probably need to figure out what why that is happening.

Re: Random Wrong password after connect to another AP

You can suggest to me other command to demonstrate the problem on radius server.

Re: Random Wrong password after connect to another AP

I do not know you infrastructure, so I would not know where to start.  Here is a query below for radius timeouts in the forum that might give you and idea.  Depending on the server, you would look in the Radius Server log to get an idea...

Re: Random Wrong password after connect to another AP

I was wondering if you knew other commands to run on controller, not on radius or on the infrastructure. To to highlight the problem.

Re: Random Wrong password after connect to another AP

The commands in your first post are the most definitive commands related to this issue.

 

I would check to make sure the ports that uplink from your controller to your switch do not have any errors.
