The D-Link ADSL2/2+ Modem with Wireless Router (DSL-2640B) is a 3-in-1 device that combines the function of a high-speed DSL modem, wireless G access point, and 4-port Ethernet router. The DSL-2640B supports the latest ADSL2/2+ standards to provide higher performance (up to 24Mbps downstream and 3.5Mbps upstream) and longer reach from your Internet Service Provider's (ISP) Digital Subscriber Line Access Multiplexer (DSLAM). Unlike a dial-up Internet service, a DSL Internet connection is always on so that you do not have to wait to access the Web. Setting up the DSL-2640B is simple since it automatically detects your DSL settings to quickly establish a connection to the Internet. With support for TR-067, compatibility with your Internet Service Provider's (ISP) infrastructure is ensured. This device also supports TR-069, which automatically updates the firmware and other settings when they become available from your ISP. With the DSL-2640B, you can create a wireless network to connect 802.11g/802.11b devices as well as a wired network to connect up to four 10/100 Ethernet devices. Share your high-speed DSL Internet connection, photos, music, videos, printers, and Network Attached Storage (NAS) with multiple users. The DSL-2640B includes a built-in QoS engine that helps prioritize Internet traffic to enable smooth Internet phone calls (VoIP) and lag-free online gaming. In addition, this device includes Dual Active Firewalls (SPI and NAT) to help protect your network from potential attacks from across the Internet. To prevent unauthorized wireless access into your network, the DSL-2640B supports the latest encryption including WEP, WPA, and WPA2. Whether it is for a home user who wants to share high-speed Internet access or for a small office that needs Internet access for conducting essential business activities, the ADSL2/2+ Modem with Wireless Router (DLS-2640B) is the ideal all-in-one broadband and wireless networking solution.
