ADSL2+ Modem Router

A Modem and Router, All-in-One

The D-Link ADSL2/2+ Modem with 4-Port Ethernet Router (DSL-2540B) is a 2-in-1 device that combines the function of a DSL modem and 4-port 10/100 Ethernet router. The DSL-2540B 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). You can also create a wired network to share your high-speed Internet connection, documents, photos, music, videos, printers, and Network Attached Storage (NAS).

Access High-Speed Internet

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-2540B 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 ISP’s infrastructure is ensured. This device also supports TR-069, which automatically updates the firmware and other settings when they become available from your ISP.

Advanced Networking

The DSL-2540B 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. With a built-in 4-port 10/100 Ethernet router, up to four network-ready computers or devices can simultaneously be connected to the DSL-2540B.

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 DSL-2540B ADSL2/2+ Modem with 4-Port Ethernet Router (DSL-2540B) is the ideal all-in-one broadband and wired networking solution.

Greater Compatibility

This D-Link ADSL2/2+ Modem with 4-Port Ethernet Router (DSL-2540B) is TR-067 compliant, ensuring that it will work with your Internet Service Provider’s (ISP) infrastructure. It is also TR-069 compliant, which automatically updates the firmware and other settings when they become available from your ISP.
