Thank you for posting in the Slingbox Answers Forum! I'm sorry to hear you are experiencing connection issues when connecting to your Slingbox 350 via Western Digital TV.
This is an issue with all Connected Devices. Our engineers are currently working on a permanent resolution. We do not yet have an ETA on when there will be a fix. However, as soon as we know when this will be resolved, we will be sure to post it to the forums.
Have a great day!
