Mam problem z bolesną niską prędkością internetu na moim Air 11 ”pod koniec 2010 roku w Sierra 10.12.2. Ani mój telefon, ani inne komputery użytkowników w sieci nie mają tego problemu. Przed wystąpieniem tego problemu użyłem oficjalny adapter kabla sieciowego.
Próbowałem już zrestartować komputer w trybie awaryjnym, odtworzyć interfejs Wi-Fi. Dla ilustracji mam

powiązać,
