First make sure that your device has the latest Firmware by checking for a new update. If an update is available, try loading Pandora again once the update is complete.

If you're still having the same problem, then please try a few standard network troubleshooting steps:

* Try connecting directly via an ethernet cable rather than wirelessly (if you have this option on your device), and see if it works better.
* Try rebooting your modem and router and restarting the device.

You should also contact Western Digital directly to troubleshoot your specific device and settings:
