From the Rack Mixer Owners Manual
2.2.1 Wired LAN Networking (Ethernet)
The easiest way to configure your control network is to connect your mixer and devices (computer, iPad, or Android) to a wireless router. This allows you to quickly connect devices for remote control using UC Surface and QMix-UC.
1. Connect your StudioLive Series III Rackmount mixer to a wireless router with an Ethernet cable.
2. Power on the router *) and then power on the mixer.
3. Connect your computer, Android and iOS device to the wireless network. You can also connect your computer directly to the wireless router using an Ethernet cable if you prefer.
4. The Control LED on the front of your StudioLive mixer will turn blue once it is connected and communicating properly to the network.
*) The router has to boot fully BEFORE the mixer is powered on.
