Hi guys,

This is my first message to the list.  We are a wireless equipment provider
in Turkey.  For one of our customers we've installed a base station and 5
satellites for internet service distribution. We are currently using 4.43k
but I am getting frequent ping timeouts from the satellites. All of the
satellites are bandwidth limited on their wlan interface to 128k.  In
addition , the ping times to the base station is also very irregular like:

To the satellite it is even worse and my last statistics said there was
about 9% packet loss.

My signal and noise levels are pretty stable and I really can 't figure out
the reason for instability.

We are using KN100 boards in outdoor enclosures with AC power supplies all
the way to the enclosure and a mini industrial PS to feed the boards with
clean 12 VDC on the adaptor connector.

Can someone point us in the right direction as to where to look to solve
this problem? 

Also I'd like to know which mode is most popular in the WISP scenario at the
base station (polling base station, non polling, ISP, ...)

I, myself, am considering using a different firmware after seeing some of
the other problems people have been having with 4.43k but I don't know which
f/w is deemed to be the most stable so far.

I'd appreciate any pointers in the matter.

Best regards
