Q. I'm using AT&T U-verse and my Gateway is showing many computers that no longer exist on my network. How can I remove them?

A. On my network, I'm constantly creating and deleting OS instances. Each time I create an OS instance and connect it to the network, the AT&T gateway discovers the device and adds it to the list of known devices. Eventually I had over 85 showing, and new machines were no longer being displayed.

There's no way to delete devices using the normal web-based GUI. The solution is to use the Management and Diagnostic Console, which can be found at

Once you're in the MDC, select the Resets link under the Troubleshooting section. Click the Clear button for Local Network and all devices will be removed and re-added as they're discovered on the network again. I performed this process, and new OS instances were once again discovered and displayed in the gateway management interface.
