Error counters OK?

I've had problems with Packet Loss from an indoor router to a outdoor ws-mini. After some testing I am sure it is the quality/length of the cable.
I replaced it and the packet loss is gone.
What leaded me in the wrong direction is that ws-mini did not show errors on this port. I guess there should be a lot FCS-Errors. Packet loss was massive.
FW=1.2.2.
Sure the error counter is correct?

Nice catch. I am buried right now and do not have time to follow this up other then send a link to this post to Eric but I know he is buried right now trying real hard to get the firmware done for the DC switch with Dave.
If you do not mind BUMP this thread in a couple weeks if there is no other movement on it.

Yes, the error counters are correct. From your description these errors should have been counted as "Rx CRC" in the Port Detail.

I checked the cable and found the ground was not connected to the housing of the plug. Seems this generates a condition where there are no errors shown in the statistics despite heavy packet loss.

Do you have your tower ground BONDED to your electrical service ground?
