After bluescreen and reload Wireless will not work

My new Inspiron 9100 with a Dell TrueMobile 1300 WLAN Mini-PCI Card crashed.
I did a complete format and reload. Everything works again but the wireless.
I have other PCs in the house that work fine....on the wireless network. I
have made no changes to the network.

The wireless icon is displayed in the system tray. In Network Connections,
the wireless icon has a red x across it & when I "View available Networks"
there are none. But in Device Manager under Network Adapters, there is no
red or yellow X. The device is enabled.

A) I have been through the MS troubleshooting steps carefully. I am now at
a loss...... Any suggestion will be greatly appreciated.
