Summary: Although I'm not a computer novice, this unit was hard to install. While the green LAN (Ethernet) light came on when plugged into the router or DSL modem, it didn't work when plugged directly into my PC or laptop. Someone here wrote that in such case you need a "crossover" ethernet cable (or adapter). THANK YOU! I learned that routers have the smarts to figure our what type of unit is plugged in, and automatically assign transmit and receive signals to the proper pins.
Summary: I bought the product 2 weeks before and I have a thought this will work with all printers but not. D Link technical support is very bad I called at least 10 times to find my printer is compatible or not. User manual is not complete so configuration is very difficult. Changing the IP Address manually and re assigning the new IP Address is very difficult. And it cause problem for other wireless divices (Mouse,Keyboard,Wireless web camera and External wireless hard disk).
Summary: After 3 hours of banging my head against a wall I finally called Tech Support. They finally figured out that this is not compatible with multi-function computers. You can learn that on their support website but no-where in the standard documentation that comes with it.
