auto wifi reconnect in guided access mode

Hi - I am using an iPad in Guided Access mode for a kiosk. I am using a browser as the main application and everything seems to be working great accept when I lose Wifi signal I can't get the browser to refresh the screen when it reconnects to the wifi. I have tried putting code into my page that say to refresh every "X" minutes and it doesn't work.

Any ideas on a setting I might be missing in the settings area that will allow for an application to refresh after losing wifi that will bring the webpage back up?

Thanks so much!!!
