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.
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.
With the function of Application Filter, you can easily set Allow or Deny for applications such as ICQ, MSN, YMSG and Real Audio/Video. If you select Allow, the router will accept the application; if you select Deny, the router will forbid the application. This is useful for home users and small office.
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.

I ran through the setup wizard, selecting VPI = 0, VCI = 38 and setting it to Bridged mode. I gave it the IP address 10.86.1.1 and a subnet mask of 255.255.255.0
I finally disabled the DHCP server on it and plugged it in to the WAN port of my router.
On my router I went in to the WAN settings and changed the connection type to PPPoE and used the @btinternet.com address as my username. I set my router LAN IP address to 10.86.0.1 (in a different subnet to the modem).
My router then correctly used the modem to create a DSL link and it's working really well - I get good speeds for my area (although I have nothing to compare to for DSL) and all the features of my already owned router.
For the price and for those who already have a good ethernet based router (perhaps from your cable provider or if you had infinity) then I strongly recommend this product as a cheap way to get DSL connectivity.
Well, I am here to refute that view! The TD-8840T is in their "newer" style which, while not exactly pretty, is perfectly acceptable (and a lot better than the retro black curvy style I refer to above). It was easy to set up with the built-in wizard (no, I didn't use the CD setup tool), doesn't get at all hot in operation (it's rated at 6 Watts max.), hasn't crashed or glitched on me once, and seems to hold the ADSL sync well. Besides the normal firewall and filtering settings, it has a fairly extensive array of features (such as SNMP, QoS, VLAN, CWMP) that most people will probably never use. The web configuration interface isn't elegant, but it gets the job done and is no worse than many others. My one gripe is that the system log facilitiy is short, cryptic and generally useless.
I bought this router to replace one of another make that was unreliable, and represents the sixth different make of router I've owned. Based on the performance of this device, I would not hesitate to buy another TP-Link product. I use it in conjunction with a much flashier (and much more expensive!) wireless device, but I like the TP-Link because this is the sort of kit you can configure once then forget about it, while it sits quietly doing its job.
NO WIFI here and NO VDSL (FTTC fibre). Just good dependable wired adsl / adsl2/adsl2+ or at least as dependable as BT will allow (we're all at their mercy no matter which ISP your on - with the exception of virgin of course).
I've had this router running a number of devices from my home (which is around 3.5km away from my local exchange) it keeps a connection of around the 4mb mark and holds the connection well (a few line issues apart which were probably down to BT it (the TP link unit) has remained pretty much rock steady.
You could pay quite considerably more for another unit using a Broadcom or Lantiq chipset - which I myself considered as many people look down on units such as the TP Link TD-8840T which use a Trend chipset.
All I can really say from my own experience over the last 18 months is that the unit has performed pretty much faultlessly and done it as quick as any other modem router I've used over the last 20 years. Please bear in mind that all telephone lines / conditions vary to a lesser or greater degree depending upon the distance you are from the exchange, the line condition and the circumstances at the exchange itself (DSLAM contention etc).
For my own personal experience, minor nit-picking aside I really can't fault the unit, especially given the price paid.
