My laptop: Toshiba Satellite C55-A-1HN
Wireless driver: Qualcomm Atheros QCA9565 / AR9565 Wireless

After a new installation of Ubuntu 22.04.01 my WIFI became unavailable. That is quite frustrating since I have had a similar problem. Please help me fix that.

    "Wireless LAN Hard blocked: yes" This suggests that the wireless switch, also known as Airplane Mode, is switched off. Find it and switch it. – chili555 Jan 04 '23 at 00:43
  • Hi @chili555 ! Thanks for your comment. After a second thought, I came to realize that you were right. Indeed, my problem was as you suggested that my WIFI antenna was switched off. Thanks again... cheers. – goldenself Jan 04 '23 at 18:50
  • Wifi is always on in Dell laptops. There is no antenna button. – Mahler Jan 04 '23 at 19:18
  • @Mahler May I have a model number where no wireless switch is provided? – chili555 Jan 04 '23 at 19:32
  • @chili555 Dell Inspiron 06F315 – Mahler Jan 04 '23 at 19:41
  • @Mahler Google says that's a motherboard available on Ebay. Do you have a link to the user manual? – chili555 Jan 04 '23 at 21:05
  • @chili555 Sorry. I don't want to share this information all over the internet. – Mahler Jan 04 '23 at 21:17

From the answer of the question's author which was originally posted in the question:

Make sure your Wi-Fi antenna is working (switched ON) by pushing the button with the antenna symbol on it as you can see in this image below. On my laptop the Fn+F12 keys turn the Wi-Fi ON and OFF.

enter image description here

This is quite a major problem: In Ubuntu, you can have the "physical" antenna turned OFF while having the Airplane Mode switched OFF. In this scenario you have no idea that your Wi-Fi is disabled, and that the only thing you need to do in order to use Wi-Fi is to push the antenna button on your keyboard as shown in the above image.
