Windows Vista Ultimate. New Dell D630 (O.S. factory installed). Sudden
inability to communicate with network either by Wi-Fi, ethernet card, or
Verizon Broadband wireless service. The message on the WiFi indicator says
Dependency service or group failed to start. The diagnosis utility says the
computer doesn't have a network card installed or configured. Everything was
working fine until all three stopped working. The Bluetooth module is still
working. Any help (and solutions) much appreciated.
