![](/p.gif) | The professional VPN router LANCOM 1781EW+ is the powerful basis of a high-speed Internet access via external cable modems. Due to its modern hardware platform it is ideal for Gigabit-speed Internet connections. With its intergrated dual band WLAN based on IEEE 802.11a/b/g/n with 3x3 MIMO the LANCOM 1781EW+ also connects wireless clients with up to 450 Mbps at both 2.4 and 5 GHz. With its extensive VPN capabilities, the device provides secure, high-performance connectivity to branch offices and remote workers. The four ports of the integrated Gigabit Ethernet switch ensure maximum performance and are also energy-efficient based on IEEE 802.3az: If no data is transmitted over an interface, its power consumption shuts down automatically. The LANCOM 1781EW+ provides everything required of a modern enterprise network, such as comprehensive Quality-of-Service capabilities and an object-oriented firewall.
