For the longest time, I couldn’t figure out how to get my wireless to on my laptop. I could enable and disable my wireless card, but I could never scan and view available wireless channels. After searching many forums, I came across an article that suggested this.
rfkill unblock all
After you run this command, disable and enable your wireless card. If your problem was similar to mine, then you should be able to see wireless channels and connect. I’m not sure exactly why this works, but it worked for me. Feel free to explain if you know why this solution works. I am curious.
I hope this helps someone out. I’m very thankful I was able to come across the solution.
