Turn on Network and Sharing Center Acer Aspire 4720z
Hello,
You need to install the drivers for those components. GO to the website of your computer's manufacturer and install the updated drivers for those hardware and make sure that the drivers are compatible with windows 8.
After installing all drivers, make sure to keep them updated so that you can avoid from getting any problems. Install RadarSync if you want to automate the driver updating mechanism of your computer.
I hope this helps!
