Недавно я обновил ОЗУ на компьютере моего отца (Lenovo ThinkPad E545), потому что он жаловался, что он работает медленно. Некоторое время все работало нормально, потом его WiFi умер на нем.
Windows 10 считает, что аппаратный коммутатор выключен, и все попытки запустить средство устранения неполадок просто говорят мне снова включить коммутатор. Все попытки включить выключатель были безрезультатными, это ничего не делает.
Я заново установил ОЗУ, переустановил старую ОЗУ, переустановил карту Wi-Fi, отсоединил и снова подключил кабели антенн, проверил BIOS и диспетчер устройств, чтобы убедиться, что карта распознается (она есть), переустановил Windows и даже загрузился в Fedora Linux с USB-накопителя (и столкнулся с проблемами, похожими на Windows).
Так что я уверен, что сейчас это какая-то проблема с оборудованием (не стесняйтесь, вставьте сюда). Но что это может быть? Опять же, карта Wi-Fi распознается компьютером, поэтому я немного растерялся.
--- Редактировать ---
Я изменил карту Wi-Fi, и проблема остается неизменной.
Вот вывод команды lspci -vvv
