I been having this issue of my wireless adapter suffering an internal error and been constantly resetting sense I've bought this computer originally with Windows 10. I've tried twice reinstalling a fresh driver before and tried a few methods I've read about on the internet. I've been having this issue sense I bought the computer in 2019, I've always just shrugged it off waiting for the reset to finish, until I got a BOSD with it today.
