Give your WDTV a static IP
Settings -> Network Settings -> Network setup -> Manual -> IP address
There you will find something like:
Example 1: 10.0.0.23
Example 2: 192.168.2.24
Change the last digit to 254
Example 1: 10.0.0.254
Example 2: 192.168.2.254
don’t touch the other numbers.
Your router automatically provides to all connected devices, an unique IP adress wthin a certain range (DHC Protocoll). e.g. 10.0.0.2 - 10.0.0.100 or another example 192.168.2.2 - 192.168.2.100
The first 3 numbers have to be the same, the last one defines the range, the biggest possible number is 255. So in the both examples, your router can provide 99 unique addresses (the x.x.x.1 is always the router itself). Everytime a device connects, it gets an IP out of this range. Everytime it disconnects the IP gets available again. So the IP can change everytime you reconnect. With a static IP, the device tells the router which IP it wants to have, this has the advantage that it always gets the same IP. Why did I tell you all that? The static IP has to be outside of the DHCP range! This means in our examples, the first available static IP would be 10.0.0.101 and in the second example 192.168.2.101.
So if you have any trouble, log in to your router settings and check which IPs define the DHCP range in order to select a static one, that works.
Please leave a note if this works for you.
To be honest I don’t know why the “fix” helped, but for me it did. All devices in an Local area network which have the first 3 digets (e.g. 192.168.1.X) in common can , or in case of the poroblem with the latest WDTV Firmware: should be able to detect themselves automatically. For all devices in your LAN you can decide seperatly if you want to give it a static IP or and dynamic one out of the DHCP Space your router offers. Still hoping this help some of you, suffering from the problem.
