Client Match not working very well on some users?

Hello I have a 7210 running 6.4 (pre-release). I have a few users complaining of disconnects randomly. When I look the users up in Airwave I show low health and very low SNR. It makes me believe that for some reasons the users are not being handed off between APs. 

 

We use AP-105s.

 

The users are mostly on Windows systems 8 and 8.1. I have PMKID turned off on the clients. What do you suppose would make clients behave this way? 

 

I would also like to say it is not EVERY client, it is a select few which leads me to believe it's a client issue and not a network issue.

Have you looked at clientmatch events to see if they correspond with user complaints?  You should be able to see the match events in airwave.

This is the Events I see. I am not sure where I would go to see client match events?

Those ARE the events.  You have alot of sticky client events and that could be because the power on your access points are too high.  I would first backup my flash and then try setting the ARM min and ARM max to 12 and 18 respectively.  That way, clients will not hang onto APs longer than they should.

Does changing ARM settings require reboot to take effect?

Re: Client Match not working very well on some users?

I almost forgot to come back and fill you in. Changing the max power has really helped with a lot of the issues. 

 

Aside from that, we downloaded the new driver straight from Intel since the Lenovo update application is behind a few revs. 

 

 

The combination of the two really did the trick for us. 

 

Thanks!

ereader22,

 

Please let us know anything else that you did, if you did to make things better.  Users always want to hear from users.

 

Thank you.

Collin i did not know this!!!

How does having high power on the AP affect the client match?

It is possible if you could explain it with more detail? i would like to understand!

 

Thanks!

I think we should ask Ereader22 what he did.  He did more than lower the power.

 

 Starting off the power between 12 and 18 means that clients can start off in a good state so that Clientmatch does not have to "fix" them in a bad state.  It is more about starting off your network healthy, rather than helping clientmatch.
