Laptop Wi-Fi is gone?

Hi @ all I have a HP6730s Unfortunately, my Wlan icon is no longer in the system tray to see and I can't connect anymore via Wlan, there are no more connections displayed. Only about the network cable is it possible someone knows why?

Then turn on the Wi-Fi active.

For the first to look at the notebook whether a switch has vorhaden, on the other hand via network adapter / network setting active

If it does not work with a reboot, try to look at the programs, if your program is still available in Windows.

If it no longer exists, use a Recovery CD and reinstall the program

There should also be downloads for you on the manufacturer's homepage.

There's a function key that can turn Wi-Fi on and off. See also https://support.hp.com/.../c01885670
