We have confirmed many users were able to fix the Code 43 issue with a power cycle after installing latest drivers, as indicated above by vampiren. Others have described a software conflict in previous page.
If you are still experiencing this issue, we will need to troubleshoot each case individually because something else is causing it. I recommend you contacting your nearest Intel® support team for further assistance:
