Intel 7265 WiFi not working after upgrade from F27 to F28

Hi all!

When I updated my system from Fedora 27 to 28, my WiFi stopped working.

Wi-Fi settings says: "No Wi-Fi adapter found. Make sure you have a Wi-Fi adapter plugged and turned on"

I'm using a Dell Inspiron 5548. My wireless card is Intel Corporation Dual Band Wireless-AC 7265

Thanks in advance for the help.

Here are some useful outputs:

$ iwconfig

I downloaded both firmware .ucode files from Linux* Support for IntelĀ® Wireless Adapters

iwlwifi-7265-14.ucode iwlwifi-7265D-14.ucode

and moved them both to /lib/firmware/ and /usr/lib/firmware/

$ ls -la /usr/lib/firmware/iwlwifi-7265*
