My context: Long-term 16.04 user but still a noob (just appreciate the relatively minimal OS). New laptop, installed 18.04, completely replacing Windows 10. Been unfruitfully trying to solve this for hours.
My problem appears to be similar to that of this post, however their solution does not work for me.
To mimic the information they provide:

Additional stuff
Ubuntu tells me "No Wi-Fi Adapter Found". There are no updates for this driver in "Software and Updates" -> "Additional Drivers" (even after checking all the additional "Downloadable from the internet" options under "Ubuntu Software").
I have tried countless solutions (that I have since loss track of) related to using GitHub repos for downloading the drivers.
Secure Boot is disabled.
Maybe important: I read somewhere that I may need to physically turn on the Wi-Fi adapter, and I am worried this may the problem because I turned off the Wi-Fi when installing Ubuntu 18.04 (was using ethernet for faster download) and have no apparent keyboard shortcut to turn it back on if that is the problem.
