CLIENT CONSTANTLY DISCONNECTING FROM WLAN

  • 1.  CLIENT CONSTANTLY DISCONNECTING FROM WLAN

    Posted Jan 27, 2015 11:54 AM

    I have a mac client which is running a windows client parallely. Unfortunately this client experiences regular and frequent disconnections from teh vlan. I did an "auth-tracebuf" and got the results below. What is the meaning of the "station down" and most importantly what can be the cause? Thanks very much in advance.

     

    (Master) #show auth-tracebuf count 50

    Warning: user-debug is enabled on one or more specific MAC addresses;
             only those MAC addresses appear in the trace buffer.

    Are the drivers up to date?

    yes they are. Is the "Station Down" in the logs normal?

    With this same client that is running parallels and therefore having connection problems, i was checking through the logs and realised that it has the same mac with 2 different IPs because of the parallel Windows running on the mac. And it keeps switching the IPs for the same MAC address. Can that be the problem and how can i solve this if it is.
