How many devices can i connect with Wi-Fi P2P?
<p>I need to connect 20+ android devices in a client-server network. Each client Android device will be communicating with the server Android device and vice versa. The client devices do not need to communicate with each other.
The server device would need access to internet for a brief period while connected to the clients.</p>

<p>My question is, can Wi-Fi P2P support that many connections reliably? And if yes, how do I go about implementing them? 
Or will I have to ensure that all devices are on the same WLAN?</p>
