The box neatly unpacks to reveal a warranty card, a simple user manual, a driver/utility disc, and a USB extension cable which allows angling of the USB-N53 to receive the best signal or to position it upwards if you don't have much room to the sides/back of your computer.

After days of working through the ASUS RTN66U router documentation, which is a poor Taiwanese to English translation, I was able to finally get it to work. It still doesn't work just right with my Vonage Box, or my Sony HDTV direct connected.

Then I bought a ASUS USB-N53 Dongle for my PC. I am now on the third day of trying to get it to work. Maybe it's just me. Maybe I am the dumb one. But after installing the ASUS drivers and utilities the Dongle finds the Router just fine, the router won't provide a LAN address for the ASUS USB-N53 to connect to. Mind you you can see the device in Windows XP, but it has a very odd predefined address, that will never connect with my router.

No way to configure the right address. No technical information to trouble shoot the problem. It seems like I am the only one with the problem.

If you like to spend days to configure network components ASUS is the way to go. There is good power and lots of parameters to configure. How you find them, what their values mean, are a different story. Good luck.
