Excellent – This is our current household unit servicing one Desktop, three laptops, a netbook, and a Nintendo Wii. I've seen some other routers fail at correctly assigning MAC-IP adresses, this one does it solidly, if you don't assign an IP to a MAC it won't connect to that machine PERIOD (if you choose to enable MAC filtering option, that is). Solid security. It's fast. It has very good range and penetration of walls, even in a steel framed brick house. Has operated flawlessly since new, even during the 40+ degree C heat-waves. Was a bit pricey, but has operated flawlessly since new.
