bob.tchida1962,
Did you recently reinstall the opertaing system? If yes, did you install the Dell Notebook System Software, v.4.5.0, A21 and the Intel Mobile Chipset, v.7.2.2.1006, A09 drivers first? If not, the rest of the drivers will fail to install.
The Broadcom 440x 10/100 Integrated Controller, v.4.37, A13 drivers are for ther ethernet connection.
