Macbook problems, code -1005F

My macbook wasn’t connecting to wifi, i restarted it and the symbol of a file with question mark on it came up, i researched how to fix it and attempted when a globe with a caution symbol appeared and the error -1005F i have tried talking to assistants and i even bought a ethernet adapter and tried fixing it with that, all attempts failed. Please help. It’s a 2015 macbook and i believe it’s catalina version 10.15.7.
