High number of Rx radio errors

  • 1.  High number of Rx radio errors

    Posted Dec 14, 2015 12:23 PM

    Hi community,

     

    At one of our sites we have a number of wireless IP handsets in use, that are strictly restricted to using the 2.4 radio in the AP225s deployed at the site. Now whilst we are not getting reports of issues with the phones, I see a high number of receive errors on each AP deployed at the site. Please see below an example taken from two APs. Can anybody advise what may be the cause of this, and if this is a potential issue, how I may go about troubleshooting it?

    Less important is the number of errors.  More important is the percentage.  In a high density/high interference environment, 4% errors is not bad.  If you are having problems with your applications, you then need to figure out a way to reduce that by removing interference, SSIDs, reducing utilization, etc.  Some low bandwith apps that are not latency sensitive can survive in this environment.  Again, if you are having problems, you need to figure out how to reduce it somehow.
