Reset Wi-Fi adapter automatically after failure(Автоматическая перезагрузка Wi-Fi адаптера после сбоя)

Возникла проблема – периодически виснет Wi-Fi соединение. Подозрение, что этому может способствовать установленные виртуальные сетевые карты от VMWare Workstation. В связи с этим, если работать с компьютером удалённо (через TeamViewer например), то после зависания сети доступ к компьютеру пропадает …

Решение проблемы:

Скачиваем и устанавливаем программку RedEyes Host Monitor

Эта программка умеет проверять состояние удалённого хоста и при его недоступности выполнять скрипты.

Используем для этой цели Power Shell.

Определяем нужный адаптер командой get-NetAdapter

Далее в меню Settings программы RedEyes Host Monitor выбираем пункт Notifications и настраиваем пункт Execute custom application:

Application: powershell.exe

Command line params: get-netadapter wi-fi | restart-netadapter

Настраиваем мониторинг на ping например хоста google.com и теперь при сбое адаптера будет автоматически выполняться скрипт powershell:
