We are experiencing latency and disconnect issues on a couple of IAPs in our cluster.

If I run a show stat command on the IAP I am seeing the following:

Util Level:good

Noise Level:good

Error Level:good

However under the clients section, all clients seem to have either good signal and poor speed, or poor signal and good speed

Clients                Signal  Speed 
-------                   ------  -----                                    
SIHS-PREP-9    good  poor             
   

Katherine   poor good                                                                                                 
SIHS-PREP-10       good    poor                                                                                                                        
android  poor    good   .                                                                                                            
0.0.0.0                   poor    good   0.0.0.0                                                                                                                           
iPhone                    poor    good  

 

Any ideas what could be causing this, and how to go about remediating the issue?

Many thanks

Richard

What is is the transmit power of the APs in that cluster?  Too much power (>18) means they can hold on to an AP longer than they should...

Thanks for getting  back to me on this.  Power has been set to Min Transmit 15, Max Transmit 18, as per a recommendation from an Aruba support engineer a while back.

Are you using Broadast Filter ARP on all of your SSIDs?

roadcast Filtering is set to ALL, with Multicasr Transmission Optimization and Dynamic Multicast Optimization both set to off.  These should be no multicast traffic on the network anyway.

 

Thanks

What version of Instant are you running and what model access points?

What are the top two devices that are experiencing latency and disconnects?

Are they ever on the 2.4ghz band?

I suspect that they are, however I will need to confirm this.

I can confirm that all the devices are on 2.4Ghz
