2-in-1 Device
The TP-LINK TD-8840T is a 2-in-1 device that combines the function of a DSL modem and 4-port 10/100Mbps Ethernet router. No need to buy a separate router, the TD-8840T is designed to allow you easily create a high-speed wired network and share it with up to four computers or other Ethernet-enabled devices to you home and to the Internet. Having this, you can avoid the cable clutter because now you have got a router inside.
Access High-Speed Internet
Supporting the latest ADSL2/2+ standards, the TD-8840T provides higher performance (up to 24Mbps downstream) and longer reach form your Internet Service Provider's (ISP) Digital Subscriber Line Access Multiplexer (DSLAM). Unlike a dial-up Internet service, the TD-8840T can get the DSL connection always on so that you don't have to wait to access the web. Besides the high-speed internet connection, this device also supports TR-069, which can automatically updates the firmware and other setting when they become available from your ISP.
Various Functions
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.
IP QoS－Control Bandwidth Reasonably
Among the wireless network, indiscriminate Internet surfing and bandwidth-guzzling downloads by internal users often leave home or small office with insufficient bandwidth. TD-8840T supports IP QoS function, allowing optimum utilization of bandwidth and offers bandwidth control over congestion, preventing the bandwidth abuse. In this way, the users of a small network receive committed and specific bandwidth, preventing non-critical applications from degrading network performance.
