Query: worked great for about 3 weeks.

All of these folks writing reviews about how great it works, just wait a while. It will break. Mine was good for about 3 weeks, now it just freezes up constantly. I know that many other people experience the same thing. Now I have to buy another one, it's not worth my time to talk to support for two hours and then return it to them. You can get a linksys for about $50.I strongly recommend avoiding D-link. BTW, the reviewers will names like "darth nerd" and "geek" work for D-link. When in doubt, check out their other reviews.
