I no longer recall if he asked me whether I had anything you declare, but I didn't, and had only a carry-on bag.
The issue with WiFi and cell service in general is being addressed. When FIS construction was taking place, the networks were removed and lets say someone forget to check if they were replaced or upgraded.
