#Broadcom ethernet controller update
It is also possible that Microsoft pushes the fixed TCP/IP stack into the monthly releases of updates to Creators' Update (RS2, 15063) earlier than the formal release of the next version. Revert to Anniversary Update (RS1, 14393) if not already done, and wait quietly until Creator Fall Update (RS3, due next autumn) which will very probably include the fix in the TCP/IP stack.Step in for most recent Insiders' build, which looks a bit like being (one of) the guinea pig.Not be fixed) you need to disable the device in the BIOS to prevent the buggy 440x driver to load As did Derek, drop the network card which driver has the underlying bug (which will.I did not read any negative report so far.Īt this point, there are several possible paths: This has been verified to work by several people (including me) and Later (June 22nd), he explained that a fixed TCP/IP stack has been pushed as part of Insider build 16226, which allows to use the computer with more-fresh-than Creators' Update releases. Doing so should cause the symptoms (hang during update, no network connectivity, 100% CPU usage in kernel) to Given the nature of support for the old driver we cannot fix the Broadcom 440x. This exposes an additional bug in tcpip.sys which causes the symptoms that have Unfortunately the Broadcom 440x has a bug where it returns incorrect responses when Windows asks it about support for the hardware optimizations. But starting with the creators update the optimizations are nowĪvailable on client versions. These features have been available on Server versions of windows for some time. New features that take advantage of some Network Card hardware optimizations that are available on newer models. As you know it has worked faithfully all those years. The best characterization of the issue given so far is IMHO a post by an Microsoft engineer signing "Travis (MSFT)" inįirst, a brief synopsis of the technical details: The Broadcom 440x is a XP/Vista era driver and hasn't been updated in many years.
The issue you are facing is known, and (sort-of fixes) are being actively developed.
