Ok. I've got a question along the very same lines as have been mentioned by others.
In the way of problem diagnosis then, presuming the workstations/client computers are not grossly misconfigured (while it's a possibility, I've had literally years of continuous operation for some of these machines with the only change being the addition of a Dlink-655).
Here's my question. I've got a couple of machines collecting data from various websites and while there is some negligible outbound traffic the lions share is inbound data requests. During the last couple of days I've noticed a gradual slowdown(over several minutes) , following a continuous bell curve (seen via NTOP) traffic volume) , and noticed that my router must be rebooted after the traffic attenuates to near 0.
As I'm usually not home to do this, my data collection does not work. My question is this. Does or has anyone experienced similar behavior and if so what was your solution or adjustments.
I've done a few things already, but have noticed the following
Outbound traffic to 174.78.110.160, a Cox Cable connection?
Disabled advanced DNS services
Wireless (disabled manually)
Time - which appears to be a problems (especially DST and NTP time settings) - disabled
QOS Engine - disabled
Traffic Shaping - disabled
So any/all input would be appreciated.
Best Regards,
Mark T.
