I purchased and connected my WD Live Hub via wireless router and everything was good.
The wireless router is no longer functioning for other uses, so I have changed out the router for a switch (hub).
I can see the WD Live Hub in the “network map” but can no longer comunicate with it.
I ran WD network set up and it says “OK”.
The problem may be with my PC, however I can connect to and communicate with my other desktop.
