While the packaging and form suggest performance, I am not at all satisfied with the product or its customer support. When my computer is plugged directly into the router (Dlink DIR-655), the connection is perfect. When I place the DES-1105 between the router and computer, the "100Mbps" blinks slowly and regularly, and my connection speed is like dial up. I can no longer access my networked computers. Perhaps, I have a defective product. After searching the web for some way to correct the issue to no avail, I caved and called customer service. The box lists "24/7" support, but the hours are Monday-Friday. An email was sent days before the phone call to tech support, with no response as of now. I'm usually very forgiving with regard to idiosyncratic electronics and non standard as well as proprietary technologies, but this is absurd. Maybe I'm overlooking something, but there's no software diagnostics available from DLink...
