My TSU9600 uses a wireless accesspoint I have dedidated to the home theater. The RFX9400 is connected using my wired lan, not the 9400's wireless. Most of the time, things work very well. From time to time, I'll press a button on the remote, and the "busy" light on the 9400 will light and stay lit, and no IR signals are sent to the flashers. This happens for both the hard buttons and screen buttons. It gets out of this state after I press a couple other buttons.

I notice it most often when the remote is coming out of screen-save mode, and have never noticed it when using the remote directly on the charge stand. I was wondering if it might be the remote's battery getting low?

Other than that, it's working great.
