As each computer was upgraded, where there had been zero packet loss, packet loss started occurring. On the last computer, before updating, we placed it on the same wiring and power source as one upgraded with new version, to make sure power supply and cat5, switches etc was or was not the issue. That computer ran fine, until we upgraded it... then it showed the packet losses. 100% sure it was the upgrade. So the question is, is the upgrade an issue, or is it find packet losses that the previous version was not? Also, that last computer to be upgraded and used for extensive testing... is a brand new computer with plenty of horsepower.

The MultiPing tool before upgrade ran 24/7 for last year... and rarely showed and packloss. Been using tool for many years.
