This is not a perfect system though, sometimes the AirPlay icon does not show up on the iPad. Which means the two devices do not see each other. So test the wireless network you use to see if it prohibits you from seeing another devices. If it does below are two possible solutions.
Create an ad-hoc or computer-to-computer network between the Mac desktop/laptop and the iPad. It is easy!
- Simply go up to the WiFi symbol on the taskbar on the desktop or laptop.
- Pick "Create Network" and you get the "Create a computer-to-computer" network box.
- Give it a name, pick either channel 1, 2, or 11, and secure it with a password if you want to.
- On the iPad, go to Settings:Wi-Fi and pick the ad-hoc network from the list to connect to it.
Use CloudFTP to create an ad-hoc network based on Daniel Chin's instructions here to access digital content on any USB storage device connected to CloudFTP.
An alternative for the Reflection app is called AirServer. The documentation states it will work over an ad-hoc network, too, so follow the directions for creating the Mac ad-hoc network above and find out how to create one in Windows 7 here.
