Падает WiFi каждые 1-2 минуты на ноутбуке под Ubuntu. Как починить?

Question

[Андрей Шульц]

Постоянно отрубается WiFi на конкретном ноутбуке. Пользуюсь интернетом в коворкинге. Вдругих местах все работает нормально.

lspci -k | grep -iA2 'net'

Что в логах?
Как определяется "падение"?

[Андрей Шульц]

sim3x, падение определяется тем, что пока не переподключишься, интернет не появится,хотя связь с роутером есть.

Логи - знать бы еще где посмотреть :-)
