How do I enable WiFi on an Inspiron 17 5000? Solved!

Since this morning, the WiFi on my Inspiron 17 5000 is disabled. I don't know why and I cannot find out how to enable it. The troubleshooter doesn't help. This just told me that the driver was up to date. The one that finally worked was Intel 3160/3165/7260/7265 WiFi driver. I solved the problem by repairing Intel 3160/3165/7260/7265 WiFi driver.
