Wireless Access

Today I was doing post survey for on customer & noticed that while a client is roaming between APs there is one ping drops. Client was pinging google.com.

So my question is:

Is this a expected behaviour ?

Or I need to work on this to fix .

It is very typical to see one or two ping drops during a roam.  Clients can scan other channels while roaming and pings are not retried, so it is typical.

Second that.

In network verification testing this behavior was saw at every site.

It's because of the re-association process that go on "behind the scenes".

- "Clients can scan other channels while roaming and pings are not retried, so it is typical.".  While a client is scanning other channels, it is not processing traffic on the data channel.  

- There also could be contention:  Wireless is a shared mechanism and sometimes traffic does not go through the first time.  Combine that with scanning when changing access points, and there could be a drop or two.

- Pings are never retried, so if it is missed, there is nothing further up in the application layer to retry a ping that is missed; it is just missed
