I just bought D-Link 802.11n wireless router and i'm glad i made the right choice. It's very easy to install and setup. I connected the router to my DSL modem. It has 2 external antennas and the wireless signal is excellent. It comes with a network magic cd that will guide you in your setup and manangement of connections. Aside from sharing internet connection, you can share printers and other files. Just follow the instructions in the manual or cd.
Don't forget to setup your own password for protection. The router also has firewall protection, secure wireless protection using WPA and WEP. Also make sure to that you have an internet connection and that you configure the connection before setting up or connecting the wireless router to your modem and computer.
If you're gonna buy a wireless router, choose the "N" type. It is much faster, transmits better and covers wireless signals at a greater distance compared to "G" type.
