What is happening to your signal in Sunward Park

Over the last 2 weeks or so your Wifi signal at the Sunward Park hospital has becom irratic. It appears that either the strength of the signal alternates or that something was moved. I sit in one position for 4 hours and every now and again Wifi connection is lost. Very frustrating if you have typed a memo on your iPad and the signal \hangs"and you have to retype all. Can you please attend to this issue. """
