Интернет в моей новой квартире очень медленный. Быстрый анализ пинга показал, что большая часть времени соединения с локальным беспроводным маршрутизатором прерывается, а затем внезапно на мой компьютер приходит всплеск ответов:

Я использую Mac (Lion) с аэропортом; та же проблема распространена на моем iPhone и Mac моего друга (Mountain Lion).
Проблема сохраняется, даже если я перемещаю компьютер близко к маршрутизатору (тонкая стена), и сохраняется при перезагрузке маршрутизатора. Отношение времени ожидания к пакетам ответов варьируется, в некоторых случаях большинство пингов отвечают, в других случаях большинство пингов теряется.
Кто-нибудь испытывал что-то подобное, или есть какие-либо предложения относительно того, что не так? Я не знаю марку роутера, но хочу дать несколько хороших предложений домовладельцу, прежде чем я снова расскажу об этом.
