App Access to Shark by Wifi

The App connectivity only works with the cellular data. Maybe try the electro App? I've didn't install it yet on mine

Electro isn't compatible with the Shark yet.

Use the pull down and check to see if WiFi is active. If you are a Android Auto or Carplay user it will constantly disconnect the Wifi.

You can get a cellular extender or DAS system to improve cell signal in your home.

Thank you for the suggestion. That could be a helpful workaround if there were any cellular signal at all. Unfortunately for me, there is zero cellular signal at my location. I have to go about a kilometre from my home to get a weak, intermittent signal.

Not a problem; are there other houses around or are you really remote? If you're on land, you could offer the telco to use some of your land to erect a mobile tower.

My home there is beachfront, so at sea level. There is a tower about four kilometers south, but with a hill between us. There is a much higher hill to the east that would be a good place for a tower. I understand that one of the cell service providers intended to put up a tower there, but discovered that the title of the land is in dispute. I expect it will work out, but I was saying that five years ago. :)
