Network drops every approx 4 minutes

Bought yesterday the WD TV Live (sigh) and after some minutes lost my share.

Looked on the forum and tada I was not the only one.

I stopped 2 services in W7

HomeGoup Listener and

HomeGroup Provider.

My WD is running for over 4 hours now  whitout loosing his share, did not only run movies but also walked throug the menu’s.

Have others tried this?
