Broadcom NIC disconnect after an hour or two [Fix]
I found on my Aurora R1 that the onboard Broadcom NIC would randomly stop working after about an hour, and required a reboot to get it working again. This is similar to a win 8.1 issue.
The fix, is to install the newest Broadcom Driver from their website under the 57xx driver heading.
Of course, WIndows 10 tries to prevent that by saying it knows that the best driver version is 15.6.1.2, and won't update to the newest one.
The "fix" is to go to the start menu > Settings > Devices > Devices and Printers
Right click your computer in the list, select Device Installation Settings
Change this to, No, and never install driver software from windows update. I also unchecked the box below, not sure if it's necessary. Save changes.
At this point, Windows 10 should function much like 7/8. I personally had removed the NIC from Device Manager, and then renamed the origional file and copied in the new one to:
c:\windows\system32\drivers\k57nd60a.sys
at this point I rebooted, and the nic installed with an error saying it couldn't load the device driver.
I right clicked on the NIC in device manager, went to update driver > browse my computer > let me pick from a list > have disk > point to the new driver files you downloaded from broadcom.
From the list I selected the NetXtreme 57xx Gigabit Controller. Installed, and poof it finally worked flawlessly.
The driver version of the "new" driver is 17.0.0.3 dated 12/17/2014, and has been up and running flawlessly for over 8 hours now.
Hope this helps some of you guys with old Alienware boxes and those Broadcoms.

Thank you for your very useful post
However I am not sure which driver to download. I have an Alienware Aurora (late 2009) - that is the Dell description.
In typical fashion I updated to Windows 10 without reading the Dell dire warning! In fact installation went OK except sound didnt work until I found very useful unoffical Windows 10 driver uppdates on the Creative Forum.
I am running a 64bit windows 10 Pro system
It has an inbuit Broadcom network "card" which the BIOS describes as LAN BCM5784
Now my problem is as you described with random internet disconnections - I have a wired connection to my broadband router - this never happened with Windows 7. I currently have the windows 15.6.1.2 driver installed
However when I look on the broadcom driver page - www.broadcom.com/support - there are mulitple drivers and no version numbers agreeing to yours. I think this may be because they have posted Windows 10 drivers in the last week. However downloading, but not installing them, they start with a "b" not a "k" and my "card" number is not mentioned.
Do I install the NetLink®/NetXtreme® I Desktop/Mobile/Server (x64) driver?
Do you, or anyone else reading this!, think it will work with my 5784 version
Any help gratefully received - apologies in advance if my question is simple - I am no computer expert!

Yes, that is the correct driver package, when you go to install via "have disk" you'll get a pretty big list, make sure to select the 57xx driver and it should work fine. In all honesty there are several drivers that will work on these cards, and I believe anything in the 16+ driver version will work.
Currently the driver version I have installed is 17.2.0.0 from their site. Windows 10 will say it can't verify this is the correct driver for your hardware, but since you have the same Aurora as I do, it should work just fine.

Vestriel, you're awesome. Thank you so much. My NIC would disconnect every 5 minutes until I found & applied your solution. It's only been an hour so far, but at least not I'm optimistic since I never made it this long before.

I have the same problem since yesterday under a Win10 install. Hard wired adaptor connection worked fine before then but today has a Code 10 Device Cannot Start. Tried all your suggestions (thanks) but get no further than the Code 10 error.
Update: scratch above. Did what you suggested by overwriting the Windows Driver file with the Broadcom file - rebooted - and Ethernet adapter now working. It is 16.8.1 (not sure how that happened) but main thing is that it works.
