freese, простите, но Ваша идея о том, что во всем виновато шифрование, выглядит не очень убедительно.
Согласитесь, она никак не объясняет резкие колебания скорости передачи.
Может быть разумнее было бы не начинать сразу строить гипотезы, а для начала получить ответы от автора темы о условиях соединения в его сети? Если он напишет, что от notebook'а до маршрутизатора 50 метров на которых стоят 4 капитальные стены и вышка сотовой связи, полагаю, Вы сами согласитесь, что проблема не в шифровании.
Вообще говоря, я предпочел бы получить информацию подобную той, которую можно найти под спойлером:
