Ethernet adapter keeps needing to be reset in Windows 8.1
I am running Windows 8.1 on a Mid 2010 MacBook Pro 15" which has Mavericks installed. I am using the Broadcom NetExtreme Gigabit Ethernet driver (15.6.1.3) provided through Bootcamp 5.1. Eventually, during use, Ethernet connectivity will be lost, and I will need to reset the adapter. I have done this using the troubleshooting section of the Network And Sharing Center Control Panel, manually in the command prompt (ipconfig / release followed by ipconfig /renew), or by disabling and enabling the driver in Device Manager. All three methods get ethernet back but it will eventually drop out again. Usually, but not always, when this happens the indicator lights on the gigabit switch that my cable is connected to will blink rapidly even though there is no traffic. It happens much more frequently if I am streaming audio/video or copying a large file from other computers on my network. One time it kept happening over and over and I had to restart Windows to stop it. I have never had any issues like this booted as a Mac, and my network is fine. Other devices can copy files and use the internet, so I don't think it is an issue with my switch, modem, or router. Are there any changes to settings for the driver in Device Manager that would cure this? Or is there another solution? Thanks!
