Connecting Ethernet causes dock to lock up?

[pf01]

Hi,

I have a dynadock U3.0 and I've started experiencing a problem where the display starts flashing and Ethernet drops out seemingly randomly.

It started just now so I tried downloading the support tool, but couldn't complete the download due to the problem, so I unplugged the network cable and switched to wireless...and it stopped doing it. I plugged the cable back in after the download completed and straight away the display blanked briefly and Windows showed the ethernet connection went from connecting to disconnected.

I searched here and couldn't see it's a known problem, any suggestions for troubleshooting this?

Support files attached.

Cheers
