Cannot connect to internet when both wifi & cellular data are activated

Question

I have setup a wifi network in my office to allow all my Apple devices to wirelessly communicate with each other. I purposely setup the wifi hub without Internet access: the sole purpose of the hub is to project data from various iPad's and iPhone's onto my Apple TV. This has worked flawlessly.
I receive a strong Verizon signal in my office which allows me to access the web on my wifi+3G iPad2.
Here is the problem: when I'm connected to both the cellular network and the wifi router (that does not have Internet access), I can no longer search the web. My belief is that even though I have a strong Verizon data signal, the iPad purposely switches over to wifi to access data, continuously searching for an Internet connection that isn't there.
Does anyone have a solution to this? Is there a way to override the iPad so it pulls data from the cellular network first, then from wifi? Please note that I do not have the ability to establish an Internet connection through the wifi router--only via the cellular network.
The goal is to be able to surf the web on the iPad using the Verizon network, and project what I'm viewing onto the Apple TV using the wireless hub. I can execute both actions separately, but not simultaneously.

Answer 1

The iPad uses wifi first for connection. If wifi is not available, it switches to cellular. I know of no way to reverse the connection. You'll have to make your connections manually each time. If you want to use cellular first, turn wifi Off.
