The link basically says to visit the Intel website and use the Intel Driver Update Utility. The utility will automatically scan your computer for devices that are eligible for an update. Hope this helps you because it helped me. I also updated my Wireless
driver while I was using the Intel Driver Update Utility since a newer driver was recently made available.
This worked for me; however, I ended up having to uninstall the old Intel WiDi driver and then restarting my computer before the setup.exe file would run and install on my computer (dell inspiron). I did create a restore point in case it didn't work, but
everything seems to be running smoothly!
I should also point out that just deleting the Intel WiDi driver also got rid of the yellow exclamation mark, and unless you are planning to try and connect to your computer to your TV wirelessly, I don't think it is something that you need. Here is a
link that explains what the driver does:
