The report I have from Realtek is that a mac80211 driver for that device is
nearing completion. I originally thought that you were using a staging driver,
but you must be using a driver from Realtek's site. Do you have the latest? I
show it to be rtl8192se_linux_2.6.0018.1025.2010. As I recall, that one does not
work on a 64-bit system.

You need to run iwlist as root to get an active scan. That is why I specified
the "sudo iwlist scan". Your prompt above looks like the regular user one. If
I'm wrong there, then something is blocking transmission. Is the module rfkill
loaded?
