I have Windows 7 Pro (RTM) installed on a DELL Precision M65 laptop.
My LAN interface reports "Cable unplugged" although the cable is inserted and working.
I have no network connection through this interface.
the onboard NIC is a Broadcom NetXtreme 57xx Gigabit adapter and the driver reports it is working correctly.
If i try to install the latest driver from Broadcom, Windows says I already have the latest driver installed!
