I was looking for an ADSL2+ modem to go with a new TP-Link TL-WR1043ND gigabit router. I prefer the flexibility of a separate modem and router than an combined modem/router. This is especially useful if I move to a fibre based internet connection in the future as I won't need to change my router only the modem.
Searching for ADSL2+ modems shown them to be rather expensive for what they are. However a few further searches on Amazon found me this very cheap TP-Link TD-8817 modem (and single port router).
Installation was very simple (I updated to the latest firmware) and I was up and running in minutes! Initially I just connected a PC to the WAN port of the TD-8817 to check out access to the internet. Following this I then connected the supplied ethernet cable to my TL-WR1043ND.
Note to anyone considering a similar setup and is a little lost on the networking front.... As supplied both routers have the same default IP address and DHCP switched on. I changed the TD-8817 from the supplied 192.168.1.1 to 192.168.0.1 and switched DHCP off. I left the TL-WR1043ND router with the supplied 192.168.1.1 address and DHCP switched on, but configured the WAN connection as 192.168.0.250 (note this could be anything you like in the 192.168.0.xxx range, e.g. 192.168.0.100), subnet 255.255.255.0, gateway as 192.168.0.1 and DNS as 192.168.0.1 to ensure internet traffic from the TL-WR1043ND passes to and from the TD-8817 modem/router. All was up and running smoothly within 30 mins. This setup has also continued to run without any rebooting for the last couple of months I've had the kit.
I thoroughly recommend the TD-8817, great value for money and it just works straight out of the box. The same is true of the TL-WR1043ND, it has a very useful USB port on it which I use to provide a network access to USB disk drive.
