Behringer X-Air / XR12 / XR18 losing network connection
Behringer rack mixers are predominantly controlled remotely, through Behringer’s own X AIR Edit software or through third-party tools like OsiMIDI Stage.
If you are running this software on Windows and you are experiencing disconnections without even touching the computer, you might be dealing with a network driver problem which can be resolved in the Windows Device Manager. Read more here.
(The article above assumes that you are using the rack mixer in a wired networking environment. If you are experiencing disconnections while using the rack mixer over wifi, make sure you are in range and you don’t use the mixer’s built-in wifi.)
