    It IS network-related...

    When using the BluOS App, audio data is transmitted to the BluOS Player and decoded at that point. When using ROON, all data files are decoded and transmitted as full PCM streams as if they were uncompressed WAV files.

    Please see this help centre article as a reference; https://support1.bluesound.com/hc/en-us/articles/200347887 - A FLAC file requires a throughput of about 4-5 MBps while that same audio stream transmitted as a PCM WAV file will require 9-10 Mbps. 

    As a result, ROON requires significantly more network throughput than native BluOS.

    If you are using ROON, please ensure you have no less than Excellent signal strength upwards of -40 Dbm as suggested here; https://support.bluos.net/hc/en-us/articles/360000220487

    Hello Tony and thanks for your reply!

    First, the 2i is located about 4 feet from my kitchen access point and when playing, it's the only device connected using WiFi as you can see in the picture below. To test the network throughput using this access point I took my laptop and did a broadband check and it ended up in network throughput of 92,88 Mbit/s (up), 68,91 Mbit/s down and a latency of 12 ms. My Roon Rock Core/Server is of course connected to the same subnet as the 2i through physical network cables Ubiquiti switches. 

     

     

    So, here is the strange thing. Even though the environment for WiFi is excellent, I only get a "Fair" connection. 

    After forcing a reconnect (from my router controller), I ended up with a new connection (NG this time), 100% network experience

    And in the end, an improved strength reported in diagnostics.

    Still not as good as I think it should be. Any thoughts?

    As mentioned, ROON does require Excellent signal strength. Consider an Ethernet Powerline Adapter if you are insistent on using ROON.

    You will more than fine using the BluOS App and TIDAL natively in this configuration though...

    I tried one more thing. Moved the access point 3 feet closer to the 2i and now it's not obstructed by anything. Ended up with "Excellent" signal strength. Is this really what is required to get a robust connection?

    Sorry Tony, I don't buy that since all other wireless Roon endpoints I have tried work without a glitch. My initial question remains though, is this something you acknowledge as a problem in your end and are working on improving?

    Hi Christian, If your Bluesound player is working fine with other services or usage such as TIDAL using The BluOS App, please contact ROON as your concerns can best be handled with them. If not, then please select Help, Send Support Request and we can help you troubleshoot your network.

    As mentioned earlier, ROON takes significant network overhead due to their system. I can not speak for other products or why they may or may not work other than the fact that those other products are not multiroom products running their own background processes.
