WD My Cloud - anyone have one?

Really struggling with it, the web interface is glacially slow.

Can access with nautilus, but cannot copy.

Have updated the firmware to the most recent, there are no support apps for linux as far as I can see.

I just use it as a network share, so it is no slower than any other network share.
You are not trying to access it over 2.4Ghz wifi? Because that is painfully slow on Windows, too.

Yep 2.4
