I have the written gouge and my NULL network works great. I don't know how to print to the AOC printers yet but that sounds like something I'm going to work on.
If you can only get onto the FedEx network, look to see what your location is under the apple at the top left. I have to change mine to FedEx (established when I created the NULL network) everytime I'm in the AOC. I must change it back to automatic to use a different connection at a hotel. I then go under the browser options and change my proxy to the FedEx proxy server. Again, I have to change it back to auto detect when I'm done.
Sounds like a pain but it is so much better than that GRID system!
