This controller is on a Dell Studio XPS machine and has been a problem from the moment I pluggied the in the machine out of the box. The history with this is that I have to uninstall the thing on a regular basis to get it to work. Some days it just won't work at all. Normally I can get it to work by uninstalling it. Today, I lost power for 2 seconds and when the machine rebooted the controller failed to reconnect. I have two other machines using the same router, wired and not that have no problem. I downbloaded and installed the latest driver and nothing. Any help with this would be appreciated.
