I am new to Linux. I am running Ubuntu 20.04 on a Acer Aspire 4752. Ethernet is working BUT when I want to turn on WiFi Linux says ”No WiFi Adapter Found”. Turn on WiFi Button does not work either. Terminal lshw -c network command gives following results - see following:

There's no pic but that's a good thing! Please don't post screenshots of commands and their results. Always post those as text properly formatted as code.

Thank you for the advice. I added the results of the ”lshc -C network” command manually.

Please try: `sudo modprobe -r acer-wmi` Does the wireless spring to life? Now does Fn+F3 remove the hard blocked: yes? If it helps, I will propose an answer.

It is not: `sudo modprobe -r acer -wmi ` There is no space between acer and -wmi. It is: `sudo modprobe -r acer-wmi` Please try again.

Is there any setting for wireless in the BIOS? Is wireless enabled in the BIOS?

Checking BIOS the only thing I found regarding network was "network boot", which was disabled. I enabled it and went through the earlier but still does not solve the problem. I added 2 pics. The 1st one showing the button to turn on Wifi which is always greyed out. The 2nd makes me wonder- stating no wifi adapter found.

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.
