1. Temporary solution: execute in the terminal: sudokill-9 ` psaux | grep-Vgrep | grep/usr/libexec/airportd | awk' {print $2}''

Two. Stable solution:

1. In the network settings, a new location has been created and "Automatic" is no longer used.

2. in "security and privacy", "location service"->; In System Services, the checkbox for Wifi network has been unchecked.

PS: My answer here is to prevent me from encountering the same problem next time. I forgot to find the original answer, so Baidu knew it would always appear in Baidu. Leave a path for yourself
