Hi,

Well I took the plunge as decided to try out DL - I got the Targus USB3 unit (ACP70USZ) - running on Windows 8 64 bit since Fedora ain't supported. Something just didn't seem right when connected over the NIC (weird occasional hiccups - totally random) so I decided to look further. I installed the cygwin ping utility and ran as administrator so that I could run an ICMP flood (stress test my connection) - sure enough, there is packet loss on the DL NIC - consistent anywhere from 1-5%. Using the same cable I connected to another USB (2.0) NIC on my new laptop and reran the test - 0% packet loss. I tried this twice with the same result.

Something is amiss with the DL NIC - don't think I should be seeing that sort of loss on my local home all ethernet setup - is this normal? Did I get a lemon? Is this some problem with my system when communicating over USB 3?

Its kind of random - sometimes I see 5% loss and other times .5% loss.

Please help - I can't live with this sort of quirkiness since I do all my work over the Internet.
