I'm using it and so far it's very good. I have it since about 1 year and half and no problems really with it with 2 notebooks and one cellphone over WiFi and another desktop by cable. Also has a good configuration in the web interface. Don't know the exact range, but the farthest I've tried was about 10 meters with some walls in the middle and signal was still good with normal speed. I guess it should support about 50 meters easily. Over all, for a home it's a good option. For an enterprise it falls short and you'll have a lot of problems.
