Wifi disappeared from settings menu and does not give me an IP address.

However:

sudo lshw -C network

will show the interface seems up and running:

 *-network                 
       description: Wireless interface
       product: Wi-Fi 6 AX200
       vendor: Intel Corporation
       physical id: 0
       bus info: pci@0000:52:00.0
       logical name: wlp82s0
       version: 1a
       serial: a8:7e:ea:54:bd:b6
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress msix bus_master cap_list ethernet physical wireless
       configuration: broadcast=yes driver=iwlwifi driverversion=5.11.0-25-generic firmware=59.601f3a66.0 cc-a0-59.ucode latency=0 link=no multicast=yes wireless=IEEE 802.11
       resources: irq:18 memory:e6b00000-e6b03fff

Also sudo iwlist wlp82s0 scanning shows a proper list of the networks nearby.

However, in Ubuntu settings there is no wireless interface shown. Also, in the indicator on the top left corner, wireless options have disappear. The card otherwise won't connect to any network although it scans all.

Any ideas?

Can you show output of `sudo service NetworkManager status` to see if the service is running? I not running, you can try to restart it with `sudo service NetworkManager restart`

Also please show us: `sudo dmesg | grep -e wlp -e iwl`

I do not know what was the problem. But after spending around 12 hours trying out every and any solution I could find in forums and here and there, this fixed the issue:

sudo apt remove --purge network-manager
sudo apt install network-manager

Haha...I just did this and now I don't have a network connection for apt to get the package. Just a heads up for anyone who sees this.

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.
