TP-Link TD-8840

ADSL2+ Modem Router


TD-8840 uses integrated ADSL2+ transceiver and a 256-MHz MIPS32 CPU.The AFE supports full-rate ADSL connectivity conforming to the ITU and ANSI specifications; MIPS32 CPU with MMU and 16-KB I-cache/8-KB D-cache is integrated into the device. In addition to the basic DMT physical layer functions, the ADSL PHY supports dual latency ADSL Framing (fast and interleaved) and the I.432 ATM Physical Layer.TD-8840 is a complete plug-and-play solution. With standard Ethernet interface, it can be directly connected to any 10M/100M Ethernet devices,supporting Auto MDI/MDIX.

The TD-8840 uses ADSL (Asymmetric Digital Subscriber Line) technology for Internet connection speeds of up to 455x faster than dial-up, while using a standard phone line. With a built-in 4-port switch, up to four network-ready computers or devices can simultaneously be connected to the TD-8840 for access to the Internet.

The device comes with a CD with an Easy Setup Assistant that helps you step by step to complete your Internet connection, wireless network settings and security configurations. This feature allows even novice users to setup the router products without sacrificing any key features, just play the AUTO-RUN CD bundled to have your network set up quickly & hassle-free.
TD-8840 not only use html (web mode through Ethernet port) to configure the MODEM but also use external utility software, too. With TP-LINK’s excellent design of circuit and high quality production, we guarantee ADSL MODEM a high performance, very good stability and easy to use.
