Hello,

I have just rebuilt a Latitude D800 for my brother, combining two not working computers into one functioning one. Have almost everything running properly. My problem is the Network Controller. It Shows up under Other Devices in Device manager with the dreaded Question mark on it.

I have seen the other posts on simliar/duplicate questions. I have followed the advice of these and downloaded the various drivers including the System Software and Chipset Drivers. After uninstalling the devices I have gone back and loaded the drivers in the order set forth by Dell. No luc, I still have a big yellow question mark.

I am slightly confused on which driver(s) is/are supposed to be fixing the Network Controller issue. The drivers suggested by the other threads indicate that they are for the Broadcom 570x. The Broadcom 570x is working fine, it sends and recieves pings and passes all of its diagnostic tests. Just without the Network Controller this computer has no internet!

Please help, the more detailed the description of steps involved in fixing this the better.
