And are you sure that those are the drivers that your hardware needs? My
cursory googling suggests it is, one person wrote "The Alfa AWUS036H
uses a completely different driver (rtl8187) than does the AWUS036NHR

...which seems to suggest that rtl8192cu is the right driver.

I want to stress here that I know nothing about your particular card,
I'm just making generic suggestions.

Google. Or see if any other wifi drivers are loaded and experimentally
unload them. If everything goes bad, just reboot. If everything comes
good, blacklist the driver(s) you have unloaded.

Then wlan0 does appear. Good - at least one driver has done enough to
make the interface visible.

Run "rfkill list". If it says anything is blocked, then you probably
have the wrong driver or a driver conflict. You can then try "rfkill
unblock all" and see what happens...

Good to hear. And did you try googling "Alfa AWUS036NHR linux driver"?
