The Internet Radio is streaming the audio source data from
the selected radio station by the broadband modem / router
and Wi-Fi network. Problems with the broadband connection
(e.g. high error rate, Internet congestion due to overcrowding)
will cause the radio to stop playing until the data stream starts
again.
If the problem persists call the Internet Service Provider (ISP)
and ask them to test the connection.
What is Buffering?
The digital audio data stream used to provide the sound
(audio) when connected to a wireless network, router and the
Internet. This data stream is transmitted in small bundles
(packets) with the time interval between the packets changing
all the time and turned into a smooth, continues data stream
by a Buffer that stores audio data to bridge the time gaps.
The buffer storage is limited and if the broadband connection
is too slow or the Internet is overcrowded (i.e. anywhere
starting at the radio station geographic location until it
reaches the connection to the modem) errors and large gaps
in the data packets can occur causing the buffer to run out of
audio data and interruptions in the sound.
Similarly the Wi-Fi network shares its bandwidth (i.e. data
capacity) with all the neighboring Wi-Fi networks and can
become overloaded causing errors and interruptions in the
sound.
The buffer will start to refill as soon as the data stream starts
again and resumes playing after a short pause (i.e. 2 or 5
seconds adjustable in Configuration mode) to prevent
constant starting and stopping of the sound.
