Product Details
The TP-Link ADSL2+ Modem Router (TD-8840T) is a 2-in-1 device that combines the functions of a DSL modem and 4-port 10/100 Ethernet router. It supports the latest ADSL2/2+ standards to provide higher performance (up to 24Mbps downstream) 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, and printers.
The TD-8840T 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 (Packet filtering and NAT) to help protect your network from potential attacks from across the Internet. Setting up the TD-8840T is simple since it automatically detects your DSL settings to quickly establish a connection to the Internet.
