I have a customer with a E1405 Laptop with XP Pro and it has the standard Broadcom onboard NIC and the Intel ABG WLan. The Broadcom NIC isn't even showing up at ALL in the device manager and the WLan can see wireless networks, but it times out trying to get an IP address and ends up with a 169 ip address. I tried reinstalling all the drivers with no success. I ordered a replacement Wlan card with no I did an OS repair with no success. There are two unknown devices showing up as Base System Devices, but I don't know what they are since I have tried to go through and reinstall all the system drivers. Any ideas?
