802.11n Wireless ADSL/ADSL2/2+ Modem Router
This Wireless N300 ADSL2+ Modem Router connects a group of users to the Internet, allowing multiple computers at home or the office to share an integrated high speed ADSL2+ connection. It features four built-in 10/100 Ethernet ports, an 802.11n wireless access point, a USB 2.0 port for printer or storage sharing, firewall protection, and QoS
for smooth and secure transfer of photos, files, music, video, and e-mail over the Internet.

Ultimate Wireless Connection with Maximum Security
Powered by Wireless N technology, this Router provides wireless speeds of up to 300Mbps*. Maximise wireless performance by connecting this Router to computers equipped with Wireless N interfaces and stay connected from virtually anywhere at home and in the office. The Router can also be used with 802.11g and 802.11b wireless networks to enable significantly improved reception. It supports WPA/WPA2 and WEP for flexible user access security and data encryption methods. There is a built-in WPS button for easy wireless setup.

Firewall Protection
The router provides firewall security using Stateful Packet Inspection (SPI)and hacker attack logging for Denial of Service (DoS) attack protection. SPI inspects the contents of all incoming packet headers before deciding which packets are allowed to pass through. Access control is provided with packet filtering based on port and source/destination MAC/IP addresses. With Virtual Server Mapping, only specific services on a local server, like web, FTP or games may be made accessible from the Internet, ensuring the rest of the machine remains protected from hackers. VPN pass-through is provided to let mobile users securely access office files and mail from home.

Quality of Service Features
The DSL-2750U supports multiple priority queues to enable a group of home or office users to experience smooth connectivity without suffering the effects of network congestion. This support for Quality of Service (QoS) allows you to enjoy lag-free transmission for applications such as VoIP and streaming multimedia over the Internet.
