Realtek 8192 firmware not loading

ra_pro · August 9, 2010, 10:35pm

I have a usb wireless stick that uses Realtek 8192 driver.

Bus 001 Device 006: ID 0bda:8192 Realtek Semiconductor Corp.

I installed 2 different firmware drivers into /lib/firmware/RTL8192SU/rtl8192sfw.bin but both fail to load:

Have I tried wrong drivers if so where can I find the correct one? Or is it something else?

Are you forcing the load? My copy of the kernel sources show that this device
should use the one in rtl8192u, not rtl8192su, and that the firmware to be
loaded is “RTL8192U/boot.img”, “RTL8192U/main.img”, and “RTL8192U/data.img”.

Thanks, all these you mention are present in the right directory but the boot log is looking for ‘RTL8192SU/rtl8192sfw.bin’ and that’s why I put it there. What should try next?

I have no idea. Those vendor-written drivers in the staging directory come
without any guarantee. Check the warning in the dmesg output. I have discovered
that your USB ID was in both rtl8192su and rtl8192u for kernel 2.6.34, but that
it is only in rtl8192u in 2.6.35. I have no idea why, but that seems to be a
clue. Try the two commands below:


sudo /sbin/modprobe -rv r8192s_usb.ko
sudo /sbin/modprobe -v  r8192u_usb.ko

Does that help? If so, you should blacklist r8192s_usb.ko by adding it to
/etc/modprobe.d/50-blacklist.conf.

the commands show that the files don’t exist. Here is the relevant output from dmesg after I deleted /lib/firmware/RTL8192SU:

You are aware that deleting firmware has no effect on loading drivers, are you not?

This warning shows a fault in the driver. It creates some objects that it never
destroys. Sloppy coding.

The firmware is not there.

Please blacklist “r8192s_usb” and reboot. Do not include the “.ko” part that I
suggested earlier. That was an error.

You did not blacklist the driver the way I asked. The wrong one for that
firmware is still loading.

ra_pro · August 10, 2010, 8:30pm

I put “blacklist r8192s_usb” in the file ‘/etc/modprobe.d/50-blacklist.conf’. Is that not correct?

ra_pro · August 10, 2010, 9:33pm

Looking at ‘lsmod’ output I can see that r8192u_usb module is loaded. So is the ‘RTL8192U/boot.img’ incorrect firmware? If I blacklist ‘r8192u_usb’ than the ‘s’ module loads and requests ‘RTL8192SU/r8192sfw.bin’ firmware which for some reason doesn’t load. What next?

As the r8192sfw.bin did not work, you need to blacklist r8192s_usb. With it
blacklisted, what does dmesg say?

If that does not work, your only other option is from the Realtek site, where
they have driver sources. I have no idea if those will work.

With the ‘r8192u_usb’ loaded dmesg says:

Do I need the driver or the firmware? Isn’t the driver either of those 2 modules ‘r8192u_usb’ and ‘r8192s_usb’ or am I altogether in the left field?

A driver is a xxxx.ko file, thus r8192u_usb and r8192s_usb are the drivers.

Which is the correct driver then? Do I need the correct firmware for that driver?

I have no idea. The correct one is the one that works. What do you think about
the firmware?
