I am seeing the same thing.  On both 4.31 and 4.43 heterogeneous and
homogenous networks.  Still trying to figure out why.

I've been noticing some rather serious jitter between our client stations
and our NOC or AP.  When I ping from the client radio out towards the NOC or
AP, I see anything between 15mS-300mS.   The ping time jitter has no
correlation to system load, but responds well if I load the client that I'm
testing from.   (Start a download from the NOC towards the client, and the
ping times drop down to 20-30mS )   Pinging back from the NOC to the client,
I see stable 10mS or less ping times.   I've upgraded all the radios in the
network up to v4.43, and have the latest firmware on the radios themselves
(PRISM 2.5).  I've even replaced radios to see if that fixes it.   The AP is
a AP1000 running base, has two radios in it, one PtP backhaul, and the other
PtMP.   Anyone have any idea what this could be?   Is it even a problem?

Norm
