DRAYTEK VIGOR 2820VN MANUAL PDF

Этот материал посвящён маршрутизатору DrayTek Vigor VG, который имеет ряд отличий от Vn, позволяющих назвать его более гибким в работе, но, в тоже время менее универсальным решением "всё-в-одном". Так же, как модель DrayTek Vigor Vn , герой сегодняшнего материала поддерживает два независимых подключения к Интернету, при этом допускается использование второго канала не только как резервного, включающегося в работу при отказе основного, но и для совместной работы и балансировки нагрузки. Интересно, что здесь, в отличие от , порт для подключения второго внешнего канала WAN2 объединён с портом для локального подключения, то есть этот физический порт можно настроить на работу в режиме локального или внешнего интерфейса. Если такой вариант второго внешнего подключения не устраивает, то, так же, как у , можно воспользоваться портом USB, подключив к нему 3G-модем или модем, поддерживающий WiMax 4G. Модель интересна функциями виртуальных сетей.

Wireless Security is comprehensive too; the Vigor Series provides several independent levels of security including encryption up to WPA2 , authentication The Web interface lets you see how many and which clients are currently connected as well as their current bandwidth usage.

The Multiple SSID features enables you to have up to four distinct or common virtual wireless access points. For example, you could have one for company usage, with access to your company LAN and another for public access which allows internet surfing only. For specialist or more demanding coverage applications, optional aerials can be used with the Vigor to potentially increase the range of wireless coverage depending on enviroment or provide directional coverage in order that your wireless transmission is focussed and concentrated into one direction only, for example into a room or across open space.

With the increasing popularity of wireless LANs, you will want to choose the least congested wireless channel Nos. The Vigor can scan and provide a list of all devices in the vicinity so that you can choose the best channel see screenshot below. Above : The Vigorn provides a local survey of other access points so that you can choose the least congested channel.
