I used to have a d-link wasn't impressed with it and went with a Cisco dual band wireless N router, couldn't be happier and in a house with 6 guys, 4 of which have girlfriends so the potential of 10+ people connected at any point in time, we haven't had any issues in terms of speed or lack of connectivity at any moment in time, keeping in mind I have unlimited internet with 100mbps speed
Just did a quick search online, the Asus routers are looking to be a better option at a cheaper price point. There are some on Amazon listed in the $100 range that are faster than mine, and I believe I paid $129.99 or something like that
