Computers with Broadcom 440x LAN Adapters Should Disable Device Before Upgrading to Windows 10 Creators Update



Users attempting to upgrade computers to the Windows 10 Creators Update with a Broadcom 440x 10/100 Integrated Controller LAN adapter device installed, should either block the device or refrain from upgrading. It turns out the adapter can be a major blocker or cause stability problems during or after the upgrade. A forum participant on the Microsoft Community forum is recommending fellow users block the device within their BIOS in order guarantee a successful upgrade. A Microsoft employee, Travis [MSFT], confirms the bug in the Creators Update affecting the Broadcom 440x driver. Here is what he had to say:


Hello.  I am an Engineer in the Windows Networking team.  I can confirm that there is a bug in the Creators Update that affects the compatibility with the Broadcom 440x driver.  We are working on resolving this until it is resolved.  We are looking at putting a upgrade block in place as erpmanila3w suggested.

Thank you for reporting this!  I will keep this thread posted if there are any updates.  Meanwhile following the steps mentioned in this thread will work around the issue (if you can call disabling Ethernet a valid workaround) until we have a real fix available.

If you have any questions please let me know. Source

I just managed to complete the update and my 440x is not working.  It says it is enabled and working but there is no network.  I did notice that my router setting was wiped out in the process.  Not sure what that was about.  I will downgrade and hopefully have my system working again.
