This probably merits a non sarcastic reply.
Digital information is either correct or not correct. There is no such thing as warmth, fuzziness or loss of detail. An enormous amount of work has been done to ensure that digital transmission is perfect. Not good, not good enough, but absolutely, god’s eye view, perfect. First there’s s error detection and correction. If a packet is uncorrectable, it’s re-sent. Buffering is used to make sure there is no loss due to re-sends. If this didn’t work, you would never be able to download an app. It has to be perfect.
WiFi is not as reliable as wired. With an overworked router, you can get failures. This is pretty obvious when it happens, and not at all like a loss of quality.
