When the IXION Maestro is turned off, all Solo:2 units will stop streaming. This is because the Solo:2 unit requires an active link with the IXION Maestro to remain online.
Solo:2 connects to Maestro through the power grid. To ensure best possible connection, always plug both the Maestro and Solo:2 directly in the power socket and not through a power strip.
Verify that the Maestro and Solo:2 connects if you plug both units to the same wall socket.
There are a lot of electrical devices around us today that can interfere with other wireless or cable connected devices. It is possible to check if a specific device like e.g LED-lights is interfering with another device by powering it off. With Solo:2 its easy to hear if the device suffers from interference than with other devices because the audio will fall out.
