A mobile app called Wifi Analyzer had the answers to both questions.
Wifi Analyzer is a free app that scans your home wireless system to discover and identify all of the devices that are currently connected to it. The devices appear in a simple list that IP addresses, MAC addresses, display names, and access points that the system is connected to. Users can customize the list to change icons and edit display names.
Because all of my devices were accounted for, so a poacher wasn’t my problem, so I moved on from the Wi-Fi scanner and clicked a second button that launched an Internet speed test. Turns out my cable company was falling short of the promised download speed by a few Mb/s. That was information I could use when I called the company’s tech support line.
