I've used quite a few modems and routers from various manufacturers, and I find D Link products to be the easiest to use and the most reliable.
I have a D Link DSL 584T to provide my internet connection at home. There is an easy to use setup wizard, where you enter your ISP username and password, set the date and time etc.
There is also a built in Firewall to protect your connection from intrusion by hackers, this is easy to set and configure.
The DSL 584T provides a stable internet connection and connects to the internet very quickly from powering on.
It is also an elegant a slim design, which easily sits on your desk, bookshelf or can be wall mounted using the holes on the case.
The enclosed user manual on CD is also comprehensive and easy to follow.
One of the better wired router/modems out there.
