Re: debian + hostapd + pptp = pptp random disconnect
Похоже проблема была не в карточке 3Com или не только в карточке 3Com.
Сегодня после 3-х дней стабильной работы pptp с картой Realtek на моём
роутере опять начались проблемы, правда теперь pptp не отключается, а
"падает" wifi сеть. При этом наблюдается следующее:
