Not sure what distribution you are running, but I am seeing problems
with NetworkManager in recent Fedora.

Could you try the following:
1) Unplug the WiFi dongle
2) (Re)load the driver (rmmod rtl8xxxu ; insmod rtl8xxxu)
3) Restart NetworkManager 'systemctl restart NetworkManager'
4) Plug in the WiFi dongle

Thanks,
Jes

Jes,

I can confirm what Drunk Cat sees. There is something different about the 
RTL8192RU as using the iwconfig utility shows no APs in the scan. I hope to get 
to debugging the problem soon.

OK - thats unfortunate. Most likely the wrong antenna path is being
enabled for it, or something like that.

Once I finish up the 8723bu/8192eu patchset, I'll try to find some time
to look at it, if you don't nail it before.

It definitely is an antenna path problem. I finally got a few scans with signal 
levels in the -100 dBm range.

No help. The name of the patch makes it sound as if it is for a 1T2R device. The 
RTL8188RU is 1x1.

Darn, I didn't have an 8188RU near me when I discovered that bug and so
I wasn't sure if it was 1T2R or 1T1R. All my other 1T1R parts work
fine with the current code.

It will not change a thing for the AWUS036NHR. It will fix a bug in 1T2R devices.

After pulling my hairs out over this one for days (if not weeks), I
think I finally figured it out.

I just pushed a patch into the rtl8xxxu-nextgen repository which makes
the AWUS036NHR v2 work for me.

That one I have never seen before - could you try and insert some debug
prints to see where the RF initialization fails?

The call to usb_control_msg() is returning -EPROTO (-71), but sometimes the 
system works. I added the following patch:

Perhaps you can recognize what is wrong.

Odd, I wonder if my code writes the reigsters out to the device too
fast. You could try adding a call to read back the RF register before
exiting the function - preferably after the udelay().
