Oppo 103D streaming issues

An update: I recently purchased a network switch which allows me to hard wire the Oppo as opposed to using wifi. I still have issues streaming Youtube. It always hesitates during any opening commercial and sometimes wil freeze up during a video. The only way to start it is to turn it off and start over. Netflix, Vudu and other services seem to be fine. Also, I have no problem streaming Youtube on my computer, just on the Oppo. Anyone else have this issue?

Actually I believe I used a CAT 6 cable from Blue Jeans cable.

This is recent; in the last couple of weeks I have had this issue.

It's actually a 103D. I run the coax out to my DAC which feeds my pre-amp so I run it through my main system. The audio quality varies on Youtube. I was listening to an "audiophile" recording of music last night and it was actually pretty decent. Most of the audio is so-so however. My Oppo is only used for DVD video/audio. I use a separate CD transport for serious listening.

Just wanted to offer a quick update here. I believe I have found the resolution. I read on another forum that it is necessary to return to the factory default settings following a software update. I did that and now it seems to be working fine again. The unit will retain your internet connection settings when this is performed.

Here's an update: The problem still exists. Are there any alternatives to the Oppo for Blue Ray DVD playback and streaming?

Thanks erik,Yeah it's well ventilated with about 5" of space between it and the next shelf. I also have it perched on anti-vibration pads so it sits about an inch higher than the feet allow. It has plenty of ventilation. I also searched the issue on a home theater forum and many people stated that the software in the Oppo is quirky. There is a way to delete cached data. I performed that function and it seems to be working better now. I had thought I would just buy a decent 200 series unit thinking that I could update beyond the issues but apparently the firmware still has weird quirks.
