The discovery utility failed to find my device on the network

yeah similar thing here. Got the drive mapped to all house computers then started losing it. File transfers stopped as drive no longer available.  Think maybe the router is changing the IP address randomly or possibly when another device asks for that IP. Anyway, changed to a reserved/static address at the router and static on configuration page. If you cant access after type in IP and it should get to login page. Very slow on Internet Explorer tho. Drive should then be viewable in My Computer.  Biggest problem I’ve had is that the latest TwonkyMedia server is not compatible with my Pinnacle Soundbridge music streamer. Still waiting for response from WD.
