There could be a number of reasons, from corrupt driver to faulty hardware, why your Intel wireless is not working. You can try the following suggestions to fix the issue:
Try a clean installation of the Intel Wi-Fi driver.
Update firmware on your wireless access point's Wi-Fi modem, router, or extender as old firmware can cause this issue as the adapter will disable itself if it receives a large number of bad frames from the access point.
Change your Wi-Fi adapter's power settings.
