Wi-Fi is a fantastic wireless technology that can work incredibly well when it is set up right. But it can perform poorly in some configurations. Here is my setup that works very, very well (used at large trade shows with hundreds of Wi-Fi networks and thousands of smartphones moving around)
1. Wireless-N dual band router such as the Netgear N600
2. Enable 5 GHz WiFi on the router
3. Connect the Wi-Fi router to the DAW by ethernet
4. Set the iPad to connect to the 5 GHz network.
The ethernet cable can be very long so you can move the router to a good place such as the center of your studio.
If you want to add extra security to the system, you can use the router configuration to set it to only connect to certain devices using the MAC address of the device.
