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.

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.

Wifi is always on in Dell laptops. There is no antenna button.

@Mahler Google says that's a motherboard available on Ebay. Do you have a link to the user manual?

@chili555 Sorry. I don't want to share this information all over the internet.

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.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
