EAP ID mismatch

[enghassanf9009]

Hi ,, I am facing connection problems with laptops when try to conect to the WiFi , I am not facing same issue with Mobiles.

when a laptop tries to connect to the WiFi it is often failed and after trying for many times it succeed.

I did debug and I figured out that the problem is the laptops are replaying too late that the server increment EAP ID  before they send the response  with older EAP ID causing ID mismatch.

Is there a way to maybe disable this check or any other work around.

or if my conclusion is wrong , please advise me .

below is the debugging output :

Hi Sir , thanks a lot for your replay .

This means that the problem is the authentication server is not available ?

if Yes why I dont face this issue with mobiles ?

the problem has nothing to do with EAP ID mismatch ?

Pardon my questions but I am trying to understand .

                  >...This means that the problem is the authentication server is not available ?

 - It depends  , lookup the mac address of  the laptop  in the authenticating  logs of the authorization server and see how the authentication for the particular mac is processed. If it can not be found then the laptop may not be able to reach the authentication server, as other user said make sure wireless drivers are  up to date.

Have you tried to upgrade wNIC drivers to latest ones?

[enghassanf9009]

Is there a command to make it  ignore  the ID mismatch ?

> Is there a command to make it  ignore  the ID mismatch ?
No - that would break the security of the protocol!

What model of controller?
What version of software?
What model of AP?
What make and model of network adapter on laptop?
What version is the network adapter driver?

If you are only selecting the SSID on the operating system to connect to, try to manually set the WLAN profile in the OS with the correct configuration. Sometimes automatic connections use improper EAP ID and you need to create the profile manually. This happen to me using Android with public signed certificates, and some legacy Windows ones.
