What does an icon that looks like a pair of connected chain links next to a wireless network name mean? (1 answer)

Closed 2 months ago.

I just stumbled across something I never saw before. When clicking on the the Wi-Fi icon in the menu bar at the top right of my screen, every available network has this "Wi-Fi icon" except one which has another icon and a "[?]" displayed as name, can someone explain what this is ? I'm running macOS Sierra on a MacBook (8,1).

Answer 1

The two-links symbol means Personal Hotspot. See https://support.apple.com/en-us/HT207354.

Answer 2

That just means your Mac does not know how to display the network name. It could be an emoji that your computer doesn't know about.
