Netgear WNA1000N uses the same chipset. This fails with Mint12, Mint
LMDE, Fedora 16 as well. Doing another clean install to Ubuntu 11.10 to
do more tests (fortunately this T23 isn't in use yet)

Just tested Precise daily of 30.12.2011, and the device still doesn't
connect.
filename:

In response to comment #40, I was forgetting blacklisting the old
driver, rtl8192cu.
Also, if the Wifi USB adaptor doesn't work, it is useful to unplug it
and plug it again.

In response to comment #42, Realtek has corrected the code, and there is
no need anymore to patch source files.

The following fixed this for me (link at the end):
to solve the linux/smp_lock.h not found error you need to edit this
two files into the archive
driver/rtl8192_8188CU_linux_v3.1.2590.20110922.tar.gz
file 1: include/rtw_io.h
Change osdep_service.h (line 49) linux/smp_lock.h to linux/smp.h
file
I can compile and install the latest driver from realtek following
comment #40 and blacklisting the original, but when I plug in the dongle
it starts connecting to the network and inmediately after it connects
everything freezes! and I mean EVERYTHING, the only way to restart the
machine is to cut
Strange. the above procedure works once for Linux Mint 12 (next time the
computer reboots I experience the same problemas) and never for Ubuntu
11.10.
Any hint please?
I don't need to patch the source files, it compiles ok.
Am I doing something wrong?
Thanks in advance for any hint.

Steps I follow:
1) Download the driver
2) Unzip RTL819xCU_USB_linux_v3.3.0_2971.zip in a directory
3) cd directory
4) sudo ./install.sh
5) It compiles ok
6) But I don't know how to install it.
Here are the last lines of output of install.sh:
make[1]: Leaving directory
I think the old module interferes with the new compiled one.

Solved!
Sorrry for the noise. I'm quite novice.
How to compile it:
1) Turn off wifi
2) Reboot computer
3) modprobe -rv rtl8192cu
4) cd directory
5) sudo ./install.sh
Hope it maybe useful to anyone else!.

The proprietary driver RTL8188CUS works fine:

To compile the driver for the 3.0 kernel you need to patch two files:
I confirm that the propietary RTL8192CU driver can be compiled
successfully changing those linux/smp_lock.h includes to linux/smp.h.
The propietary driver works fine.
Thanks a lot, chicoff, you've saved my 11.10 install :-)

Just tested OpenSuse RC2 with the 3.1 kernel. Same problem, APs visible,
won't connect. Looks like the driver needs to go back to the testing
branch for another year or two.

I've messed around with this a bit and I think, at least,
the rtl8192cu driver needs to be rewritten to eliminate the BKL (big Kernel
Lock).
Where is the documentation that explains the BKL and how to replace it
in drivers?
The BKL calls are defined in smp_lock.h.
Is smp_lock.h included in any

I've gotten in touch with upstream developers, they suggest running
wireshark to isolate the issue. I don't have a lot of experience with
wireshark, but I'll give it a try if i can find a bit of time.
