Hello;
I must be mature too admit when I'm wrong, (I'm very wrong, and stupid);
 I was too quick to judge. : (          (apologize firefox)
I had overlooked one aspect of the situation: "wpa_supplicant",
After watching wpa_supplicant do it's job, I had noticed that it keeps
CTRL-EVENT-DISCONNECT - Disconnect event - remove keys,
and CTRL-EVENT-SCAN-RESULTS and trying to associate with
XX:XX:XX:XX:XX (SSID= XX freq= 2462 MHz).
anyways despite the manual jargon of wpa_supplicant; basically
whenever wpa_supplicant disconnects  and reconnects  the keys
I had noticed flash player, and any other connection's to stop or even
pause during the playback, depending on how well the transmission was.
So for now as for what I can see: wpa_supplicant is the main cause of
my troubles.
regards,
