У меня есть MacBook Pro середины 2014 года, который испытывает очень переменную реакцию на пинг по WiFi. Сотрудники, использующие одну и ту же сеть Wi-Fi, не сталкиваются с той же проблемой, поэтому кажется, что проблему можно сузить до моего собственного MacBook. У меня практически нет служб, работающих в фоновом режиме, но все равно мой пинг выглядит так:
$ ping 192.168.123.1
