## Overview

The Lancom 1821n Wireless ADSL Router ISDN delivers robust 300 Mbps dual-band Wi-Fi with integrated ADSL2+ modem, advanced security features including Stateful Inspection Firewall, and versatile connectivity options such as ISDN and USB 2.0.

## Description

LANCOM 1821n Wireless ADSL Router ISDN The LANCOM 1821n Wireless has everything you need for location networking: In addition to its 5 integrated VPN channels, which can be expanded to 25 using a VPN option, it already has an ADSL2+ modem on board. This allows the device to be connected to the Internet without an additional modem. Versatile connection options, e.g. via ISDN, the four separable switch ports, the serial interface and the USB 2.0 port allow the connection of telephone systems, network devices or provide alternative configuration options when the device is not accessible via IP. A load balancing can be carried out for up to four wall connections. High quality safety features such as the Stateful Inspection Firewall with Intrusion Detection and a Denial of Service Protection ensure safety. And that's not all: thanks to the Wi-Fi module, it works at 300 Mbps and thus creates significantly more range than its predecessor. As the wireless coverage is significantly improved due to the integrated MIMO technology, additional access points can often be avoided in smaller branches. As multi-SSD can set up to 8 user groups, Wi-Fi guest accesses that should be safely separated from the corporate network are completely unproblematic.
