Today, I even tried another Win10 notebook with AIR 2.1.3 wifi streaming online lossless FLAC music (16/44.1) for over 3 hours, and no dropout, stuttering or white noises. The notebook, btw, is wirelessly connected to another router which is different from the router that connects my Le200. That's how robust AIR 2.1.3 with Win10 now. My notebook is Acer Aspire 5750G, i7 2670QM CPU, 8GB RAM, and is more than 4 years old.
