No WiFi on Fedora 30

Question

sorry to jump directly to the issue, but I am facing quite a frustrating issue on Fedora 30. I have been using fedora on both GNOME and Deepin desktop environment till yesterday. Till yesterday I was having an option for Wifi on both Deepin and GNOME, but because I got bored with Deepin, I removed it yesterday using sudo dnf remove "Deepin Desktop".

Now, today when I booted up my laptop, I saw no option for WiFi which usually appears on the top right drop down menu.

I have faced a similar issue when I used to run Ubuntu 18.04, so I knew that I could run wifi using terminal. When I ran ifconfig -a, I got this;

But no wireless card is detected in this. So I went to WiFi settings, where I found the message shown below.

I have totally wasted my 6 hours trying to fix it myself. I tried sudo dnf install broadcom-wl and then sudo dnf update and finally rebooted, but nothing worked.

It all happened after removing Deeping Desktop Environment yesterday. Even after removing it yesterday, the WiFi worked for as long as I didn't shut down the laptop. Today, as I booted it up, nothing, the WiFi was gone.

Please help me with this issue.

EDITS:

Some points worth mentioning.

1. I am on dual boot (Windows 10 and Fedora 30) and WiFi is perfectly working on Windows.

2. As of yesterday, after removing Deepin, I had 3 other DE -> a.) GNOME b.) GNOME Xorg c.) GNOME classic. Today, GNOME Classic is also missing.

Its like my system has got messed up!

Answer 1

i resolved this problems by download new driver *.ucode (my wifi card is intel). put it to /lib/firmware and restart.
