I am running Ubuntu 20.04 My laptop has a broken wifi card. So I installed a USB wifi card in this device. But sometimes PCI wifi shows up in the settings and then it creates problems like not connecting to wifi easily. also my laptop hangs a lot when PCI wifi shows up.
I want to remove that wifi and use only my USB wifi.
Here are some command outputs that could help.
