I have tried setting up the 68u as a router, AP and a Media bridge. The only successful setup was the media bridge config. It seems there is some kind of failure that the device is expereincing every time a USB device is attacted. Be is either ports or be in powered or portable. I have sent the device to ASUS serive and they say there is nothing wrong with it. I have no idea what exactly seems to be the issue and how to solve it.
