BTW, the "rtlwifi" family of drivers in Linux kernel (which includes
things like rtl8192cu and various others, and which used to live in the
"staging" part because it was not a well-enough behaved citizen) has
been removed in Linux-5.2 because there's a newer replacement in the
works which is supposed to be included (not in "staging" this time)
soon:

So maybe you should try that newer one.
