The only codesets that come up are 9406 & Custom.

So I tried the Try & Learn feature that you suggested, I used the feature the learn the On/Off power button. RC9800i would say that it learned the button, but when I went to Try the DSM would not turn On or Off and the RC9800i would make a ping sound.

I sent an email to D-Link to find out if their remote sends more than just an IR signal, but I haven't heard back yet. Do you think that could be the cause?

Or could it be something with my wireless network settings. I am using a D-Link AirPlus Extreme G wireless router to connect my PC to the extender and haven't been able to access the media server to view pictures/music/movies from my PC.
