Recently, I installed Ubuntu20.04 on my brand new laptop, but I cannot connect to wifi as it says "No Wi-Fi Adapter Found."
Following is some of the information that could help you to understand the issue better.
Wireless Adapter: Intel® Wi-Fi 6 AX210 160MHz (Pre-installed when bought)
Laptop: Galaxy Book Flex 2
( *** I went to Samsung Service Center in case it was a hardware issue, but it turned out to be fine with the wireless adapter itself. ***)
OS: dual-booting with Windows 10 and Ubuntu20.04
Kernel version (# uname -r): 5.13.0-051300-generic
Driver firmware (saved in /lib/firmware): iwlwifi-ty-59.601f3a66.0.tgz
( *** Since my wireless adapter did not have the right Linux firmware when I first noticed this issue, I both upgraded my kernel from 5.8 to 5.13 and placed the latest driver in /lib/firmware and load the driver with the command #sudo modprobe iwlwifi ***)
Wireless performance on different OS: wifi works fine on Windows 10, but only on Ubuntu, from the get-go, it does not.
Other settings:
disabled the "fast-boot" option on Windows
disabled the "secure boot" from grub

For days, I have tried many approaches online, but none of them seems to work. Any piece of advice would be greatly appreciated. Thank you very much.
Best,
