IAP interference issue.

Hi all,

 

In one of my client place, they are facing interference issue with IAP 105.

Result :- extremly slow network.

 

Please give me some suggestion on how to minimize interference.....

Re: IAP interference issue.

You have a large number of SSIDs. Are all of these enabled on most of the APs?

Re: IAP interference issue.

More SSIDs= more traffic=reduced throughput.

 

Show us the page with the AP Utilization on it.

Re: IAP interference issue.

Those SSIDs are still beaconing at the lowest rate, and that creates traffic utilization:

 

 

 

Please see this traffic calculator by Andrew Von Nagy here:  http://www.revolutionwifi.net/blog/p/ssid-overhead-calculator.html

 

In addition, if those SSIDs share a VLAN, copies of each broadcast are sent to all of those SSIDs.

Another big problem that you have is that you are bonding channels on the 2.4ghz side.  That by itself will cause massive  interference.  You need to Disable Wide channel bands before your network melts:

If you are having roaming issues, you need to make sure that the ARM min is as 12 and maximum at 18 to start.  Clientmatch does not help roaming.  It tries to help after the client has already roamed, but getting the maximum and minimum power correct is crucial for roaming to work properly BEFORE clientmatch works.
