В связи с отключение дома от ADSL, планируется замена оборудования.
На продажу роутер DrayTek Vigor 2820Vn работает с двумя операторами сразу по разным схемам и 3G свистками.
4 года честно трудился дома без единого глюка.
Тянул домашнюю сетку на 16 гнёзд, три WI-FI точки доступа (личная, и гостевая сетки), вход городского Московского номера (плачу только за номер), все исходящие звонки с городской трубки он раскидывал на двух SIP операторов, несколько удалёнок, VPN, и куча прочего другого.
Покупаю такую же машинку только на других интернет операторов.
Цена: 7 000 рублей.
