I currently have ubuntu installed on my pc and Im trying to connect it to wifi using Intel I211 adapter, but even after downloading and installing drivers for I211 for linux system from Intel official site, system shows that adapter is unavailable and in wifi page the only message I see is - "No wifi adapter found".

I have installed different versions of drivers. I have reboot my pc a lot of times, reinstall all drivers (That was possible). (Adapter is working on windows) I really dont know what to do. Maybe its better to swich back to windows?

The i211 device is ethernet, not wifi. So far, we see no wifi device at all. Let's see: `lspci -nnk | grep 0280 -A3` and: `lsusb` Welcome to Ask Ubuntu.

Here is your wifi device: ID 2357:0138 TP-Link 802.11ac NIC

Please obtain a working internet connection with the perfectly working ethernet and open a terminal and do:

sudo apt update
sudo apt install --reinstall build-essential dkms bc git
git clone https://github.com/morrownr/88x2bu-20210702.git
cd 88x2bu-20210702
sudo ./install-driver.sh

Reboot. You should be all set.

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.
