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
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.
