Hello everyone, it’s been a short time that I use bazite on my computer, I’ve always been with linux mint usually, I’m writing here for a doubt I have about bazite, I practically couldn’t find a wifi + bluetooth adapter that worked, as I took the ones you find on aliexpress and they only go on windows. I was desperately trying to make them work and I ended up doing all these commands on the terminal, after which I finally found one on tp-link’s amazon that works without problems. Now I wanted to understand based on all these commands that I made, if I have corrupted something in the system, or maybe I can have problems with wifi such as drops in performance or crashes I don’t know why occasionally the wifi crashes but I think it is a problem with the wifi that I have recently. But in doubt I wanted to understand if there is no problem or I should actually solve something, hoping maybe that I don’t have to reinstall Bazzite, I’m will wait for an answer and these are all the commands i used for try to make those wifi usb adapter work
