In Ubuntu 22.04, I purchased a wireless LAN card to do AP mode, installed a Linux driver, and made various attempts to do AP mode, but it didn't work.
The iw list command recognizes the wireless LAN card and Wi-Fi comes out, but the Internet connection is not working.
I thought the AP mode was the same as the hotspot, so I operated the hotspot, but the Wi-Fi is not coming out on my phone and the QR code is not connected even when I scan it.
It didn't become a hotspot, so I tried it because other sites said it could be solved with a downgrade, but I couldn't get the wifi.
How can I solve the problem?
