Dell D6000 - Slow ethernet

[AndyA]

Hi- I have found multiple occurrences in my environment where the external screens flicker usually after the Windows 7 Enterprise screen has locked and the user unlocks it. Typically what we are seeing is a flashing mouse on the screen, Internet Explorer pages come up as blank white and then become painted on the screen as though the mouse were a paintbrush. Internet Explorer begins to freeze and only a reboot fixes the issue.

I will get the logs and send them.

We have a laptop with the D6000 dock, and even after updating the BIOS and drivers for the system and installing the 8.3M1 displaylink software, we are still receiving slow and random performance from the dock Ethernet. Running Google's speed test, we are receiving a speed test that varies from 30MB down/6MB up to 97MB down/6MB up. The download speed test is normally in the 50-60MB down range. We are on a 100/7MB connection.

If I switch the Ethernet cable to the onboard nic on the laptop, I consistently receive 95-110MB down and 6MB up.

Dell has already replaced the dock once, and the replacement dock has the same performance. We previously had 2 19" low resolution screens connected and were affected by the previous bug, but now have 1 27" QHD screen (2560x1440).

Any thoughts or suggestions on how we can consistently get the max performance?
