Originally had WiFi connection to my Wave Sound-Touch IV, but no longer. To re-establish the connection, I connected my laptop to Wave pedestal, as instructed in the app. Result: "cannot find speaker." I've unplugged the unit from the wall then re-plugged again. Have restarted the WiFi box. Still not able to make connection. Also wonder why connection was lost. Will a break in power require a new installation? Any help will be appreciated. Otherwise, Wave is excellent. Also noticed it is listed in my Amazon Alexa but is not showing as connected.
