Беспроводный через раз видится то как wlan0 то как eth1. При чем
цепляется за точку доступа еще реже. Пробовал как через etcnet так и
через NM. Сразу после инсталяции (p5 desktop) система вроде видела все
хорошо и цеплялась номрально. Глюч вспылыл позже (после
distr-upgrade'а?) Совсем нихрена не понимаю.... Куда копать? Спасибо.
