Update. I have had success maintaining the WIFI connection by using a wakelock (partial) in combination with a wifilock. Now my app successfully maintains the wifi connection even when the screen goes black - albeit at cost to battery life.
If anyone has any other insights they would like to share, those would be most welcome.
