I am a network administrator with a lot of experience with various routers, switches, hubs, etc. Wireless is still a relatively new technology but I think the lastest revisions of this model work fairly well for what they are designed to do. I am somewhat dismayed that most of the router manfucturers have off-shored their tech support. I would guess that D-link just followed suit so they could compete on price. I have one of these in my home. I have it connected to DSL modem, wired to the desktop and wireless to the laptop. The range is fine and it provides a reliable 24/7 Internet connection.
