Есть проблема - стоит и работает маршрутизатор (871). Приходят нехорошие люди и включают сварочный аппарат практически над ним (ремонтируют крышу). Естественно, сеть разваливается с сообщениями вида"Disassociated because sending station is leaving (or has left) BSS"
Однако, после отключения источника помех сеть не восстанавливается, а "sh dot11 statistics interface" показывает принимаемые пакеты, а счетчики отправленных на нуле.
Помогает только перезагрузка.
Спасибо заранее за помощь.

Дополнение.
Ситуация была повторена путем откручивания антенн.Nov 20 12:25:54: %DOT11-6-ASSOC: Interface Dot11Radio0, Station island 0013.0270.7475 Associated KEY_MGMT[WPA PSK]

*Nov 20 13:17:20: %DOT11-6-ASSOC: Interface Dot11Radio0, Station 0016.e3a3.5518 Associated KEY_MGMT[WPA PSK]Что интересно, отсутствует запись о 0016.e3a3.5518, хотя клиент утверждает, что производил пересоединение как минимум один раз. В то время , пока были сняты антенны, производился "dot11 do0 linktest target 0016.e3a3.5518", который всегда выдавал успешный результат, пусть и со сниженной скоростью.
Однако, в результате все равно машины от сети отключились.WiFi сокнфигурирован как bridge, вот конфиг:

Еще дополнение.После повисания помогает выключение/включение интерфейса do0.
Как решил проблему?Отпишись плиззз...
