I was annoyed to discover that my success in connecting the internet radio to the WiFi was short-lived. It was now prepared to connect, but after a short time (varying from hours to seconds) it disconnected and fell silent. The manufacturer of these devices gave up on them years ago, but the underlying system has been kept alive by enthusiasts and is now known as Lyrion. Looking for a solution I stumbled on a firmware update made available by "Ralphy". I recognised the name and decided to trust his upgrade.
