It can be connected to the home network via RJ45 or WIFI. The connection is stable. Never had any problems.

Using a separately purchased adapter (Hama SAT adapter / F-connector to coax connector), I connected the output cable of the Sunrise TVBox to the connector for the DAB+ FM antenna and was thus able to feed the FM radio programme from Sunrise into the Sonoro A580 device. It works well, but of course not at the same time as using a DAB+ antenna. For me, this is a temporary solution until Sunrise makes the DAB+ cable-ready programme available.

No, you can't.
