"From Microsoft's The DevCon command-line utility functions as an alternative to Device Manager:
The DevCon utility is a command-line utility that acts as an alternative to Device Manager. Using DevCon, you can enable, disable, restart, update, remove, and query individual devices or groups of devices. DevCon also provides information that is relevant to the driver developer and is not available in Device Manager.
See Using Devcon for more info.
You may therefore use :
devcon listclass Net
to figure out the name of the network adaptor in question, then just make a bat file with for example
devcon disable *ven_14E4*<br/> or devcon enable *ven_14E4*"
