No WIFI adapter found Ubuntu 20.04.3 LTS

ng flag

In wifi settings I get "No wifi adapter found. Make sure you have a wifi adapter plugged and turn on". Once I installed Ubuntu 20.04.3 LTS I had this problem first time but somehow was able to overcome it. Unfortunately after few months I tried to use bluetooth but it also did't work. Trying to fix it unfortunately get me back to no WIFI adapter found error. Tried many solutions without succes. Currently lspci -knn | grep Net -A3; rfkill list show:

    Subsystem: Intel Corporation Wireless 8260 [8086:0050]

my laptop is dell precision 7710. I can't find any hardware switch to turn dell-bluetooth or dell-wifi hard block to no. Previously for a moment had windows and wifi worked fine. Currently linux is my only system. Can someon help? What other logs should I post? Thank you.

To remove Hard block from Wireless and Bluetooth, try:

Fn+PrtScr.

As per Dell Precision 7710 Mobile Workstation Keyboard Guide, key combination of Fn+PrtScr would toggle wireless on/off.

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.
