[saroj pradhan]

Hello,

the is one  issue i see in the Log  of the AP  when the user  report  frequent disconnect  of  the wifi on his laptop.

*Nov 30 04:34:50.176: %DOT11-6-DISASSOC: Interface Dot11Radio0, Deauthenticating Station 0026.b6ee.9406 Reason: Sending station has left the BSS

*Nov 30 04:34:50.203: %DOT11-6-ASSOC: Interface Dot11Radio0, Station   0026.b6ee.9406 Associated KEY_MGMT[WPA PSK]

please help what is the issue.

Thanks,

Saroj Pradhan

I don't think that is possible with autonomous. And if everyone is on the same vlan, you might as well just have one vlan. The reason for multiple SSID's is to be able to place traffic in certain vlans so you can control traffic with ACL's, filter or whatever. It's also used at time for QoS purposes. So in your case if you don't want to create multiple vlans, then just stick with a single SSID. If you had a WLC you would be able to do what you wanted.

I dont have WLC to controll .  Actually  i  30 -35  users to access the WAP  for which  i wanted to  loadbalance users with  different SSID in the same VLAN.  If not then any other way  so that  the users will no face problem of wap disconnect.

i am using MAC Addess Filter  for authentication also.

Thanks,

Having multiple SSID's doesn't load balance anything since they are all still associated to the access point. If your having issues with clients being disassociated, then I would look at other things like interference, client drivers, etc.

Can you please clear on Interferace  .

Thanks,

[Scott Fella]

Well interference can affect the wireless in general but most of the time on the 2.4ghz. Reading this thread, if its a single user really complaining, then I would look at that users laptop. Make sure the driver is the latest version, make sure that the wireless adapter configuration is default and not been changed around. If you had a wireless issue, it would be affecting most or all of the users.

There are  two  WAP ( AP 1142 and AP 441N) in the  same building   in a  distance  of  20feets  distance . Can it  conflict  with the singnal of the WAP ?  I found some times the WAP  441N goes down .

Thanks,

Saroj

[Scott Fella]

Well when the WAP 441N goes down, then users will drop... there is no true roaming with stand alone access points so maybe just leave the 441N off and see if that helps.  I'm also assuming that the SSID's are identical on both AP's?

Thanks,

Scott

Yes  the SSID's   are  identical   on both AP's.

Will check when 441n will off.

Thanks  for the  valuable  Informations  sharing with me  in all our conversations. 

Thanks,

Not something to do with the users laptop and power save perhaps?

Sounds like a client device/driver issue as the other chaps say.

[NXO1Mikelees_2]

What's the roaming aggressiveness set to on the client? Have you ruled out that the client isn't flipping between two access points?

[saroj pradhan]

Hello,

i have  monitor the  cisco AP1142 and  found  that  after  some  intervals  of time   all the users disconnected  from the WiFi connection.i have  tested with two  laptops  and  run  same ping test on both the LAPTOP'S and found  discinnected   after  30-45 minutes.

Please advice.

Thanks,

Saroj

This is tough to troubleshoot. So did you shut off the other AP? The clients have updated driver? How many wireless profiles does the client device have? When a client is disconnected does that mean its not connected on the wireless or it gets a 169.x.x.x address?
