It’s both Windows 7 machines and it doesn’t matter if I’m using LAN or Wi-Fi, although Wi-Fi does sometimes work but takes ages.
I also noticed, that Fuppes is now starting to display videos as “unsopported format”, which is a change to earlier.
Support asked me to connect the Drobo directly to a PC and check if the problem still exists. Strangely it works when copying files. But only at 10 MB/s which might be a reason, since I have bigger problem if the speed gets higher.
So far, I did not have any bad experience with the Windows 7 network stack, except the NIC termination while copying to the Drobo lately.
Maybe I’m “special” (I’ve been told so in the past ;))… my Win 7 network would just get progressively slower. Meanwhile my wife’s machine that sits right beside (and is also Win 7) would be perfectly fine. They’re both on the same network segment too. shrug
Anyway, back to your problem… Files copying at 10 MB/sec… Can you check whether Windows is reporting a Gigabit or 100 Mbit connection? Possibly it’s a flaky cable. Of course the Drobo itself isn’t ruled out yet either.
