I recently installed Ubuntu 18.04 on Mi notebook air. But, I couldn't connect to the Wi-Fi and it tells me that "No Wi-Fi adapter found"
Things I have Tried
Followed the link https://help.ubuntu.com/stable/ubuntu-help/net-wireless-troubleshooting-hardware-check.html
Typed :
lshw -C network

To know about chipset,
lspci -vvnn | grep Network
Result
00:14.3 Network controller [0280]: Intel Corporation Device [8086:02f0]
Driver for PCI device
lspci -vvnn | grep -A 9 Network | grep Kernel
Result:
Kernel driver in use: iwlwifi
Kernel modules: iwlwifi
I also checked the kernel version
uname -srm
Result:
Linux 5.0.0-37-generic x86_64
Then from https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html, I downloaded iwlwifi-9000-pu-b0-jf-b0-34.618819.0.tgz
based on kernel version and copied the files in
/lib/firmware although I am not sure if its correct. Then I restarted laptop. But still the Wi-Fi is not working.
Furthermore I followed the steps from Here, but Still not working.
