Brian, thanks for your response. Sorry for the delay in uploading the required information. I didnt know which package this bug belonged to so I left it unclassified. I'm sure the more experienced guys here can classify it better.

Hans, there are couple of key differences between this bug and https://bugs.edge.launchpad.net/bugs/401126 . This bug is for the RTL8192S*U* USB based device rather than the RTL8192S*E* PCI device.

I downloaded the mainline 2.6.32 dailybuild kernel source, enabled the staging drivers and compiled it. The device seems to work. But I had to search for the firmware which I found on the Internet. Not sure if it is to be trusted. The filename is: rtl8192su_linux_2.6.0002.0708.2009.tar.gz . It seems to be an out-of-tree firmware but could not get any solid references. After installing the firmware in /lib/firmware/RTL8192SU/ the device worked. I am able to connect to all wireless networks ( WEP / WPA2 ). The connection seems to be stable.

Can we get this driver backported to the current 2.6.31 kernel in Karmic?

Dinesh,
thanks for the filename to search for. copying the directory
rtl8192su_linux_2.6.0002.0708.2009/firmware/RTL8192SU (containing rtl8192sfw.bin)
into /lib/firmware, unplugging the usb adapter and putting it back in worked great - instant N connection.
Didn't need any kind of kernel patch with 2.6.31-16-generic - I think we just need to get the firmware added to restricted modules (if restricted???) and folks can use this adapter.

Ryan,
I have tried what you suggested, but Ubuntu (karmic) freezes immediately and the caps lock key begins to flash. I have not yet try a kernel patch.

Ryan, thats a no-go on -16 or the newer -17 kernel. My system still freezes up. It seems a lot of bug fixes went into the driver which are present only in the 2.6.32 series.

Still not working in the 2.6.31-19 kernel on Ubuntu Karmic

Hi, I'm using:
- Ubuntu 9.10 64-bit
- Kernel 2.6.31-19
- USB Wireless adapter AirLink 101 -> Golden N, adpater, model AWLL 6075, which uses rtl8192su chipset, recognized by lsusb as:
  Bus 001 Device 010: ID 0bda:8172 Realtek Semiconductor Corp.

And it doesn't work. nm-applet says "El dispositivo no está listo" ("Device is not ready" -translated by me).
I downloaded and installed kernels 2.6.32 and 33 and they neither work. I did some tests and my system freezes too, with the Caps blinking thing.

There are several changes for the rtl8192su in the 2.6.34-rc1 kernel. A PPA of this kernel can be found at http://kernel.ubuntu.com/~kernel-ppa/mainline/

Hi Dinesh,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 492034

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I can reproduce in Lucid amd64. I'm using the mvix solido which uses the 8192SU driver (although it has the 8191 chip)
I'm running the 2.6.34-rc6 kernel. When I copied the firmware directory as indicated above, the firmware downloaded and the wireless device began to work (sort of. It can scan stations but not connect, but thats probably a separate issue)

Sorry for the delayed response. Yes, this is still an issue with Lucid Lynx x86 and x86_64. IIRC, 2.6.32 staging driver is far more stable. I tried compiling my own kernel and confirmed it. Please note, the firmware for this device is still not included in Lucid.

I am running the mainline kernel 2.6.34-020634-generic on Ubuntu 10.04 Lucid Lynx (with all latest updates applied) and the wireless N adapter described above does not work automatically. I got the same messages in the dmesg output as the OP shows.

I copied the firmware off the CD that came with the adapter and it works.

Details on how to do it here

http://gurrier.wordpress.com/2010/06/18/inexpensive-802-11n-wifi-usb-with-ubuntu-10-04-lucid-lynx/

lsusb shows
Bus 001 Device 010: ID 0bda:8172 Realtek Semiconductor Corp.

Hi Tony,

Thanks for your feedback. Could you possibly post the firmware somewhere (
along with the md5 sum )?

Thanks

Dinesh

I have a problem with Belkin version of this USB device.
Using kernel drivers I'll never been able to connect ( also tested using various kernel and gentoo, mandriva and fedora distro with the same results)
After some time I can see only the password input box

If I compile the sources from the realtek site all works fine, but only on 32bit os, this driver does not work under amd64 environment ( the system crashes once loaded the driver )

We have just confirmed this bug using the LiveCD of Ubuntu 10.10 with the the following device:

Bus 001 Device 006: ID 0b05:1786 ASUSTek Computer, Inc.

After connecting the wifi stick, the driver r8192s_usb cannot find the firmware:

rtl819xU:FirmwareRequest92S(): failed with TCR-Status: a
rtl819xU:FirmwareDownload92S(): failed with TCR-Status: a
rtl819xU:FirmwareRequest92S(): failed with TCR-Status: a
rtl819xU:FirmwareDownload92S(): failed with TCR-Status: a
rtl819xU:ERR!!! _rtl8192_up(): initialization is failed!

rtl819xU:FirmwareDownload92S(): failed with TCR-Status: a
rtl819xU:ERR!!! _rtl8192_up(): initialization is failed!

looking at:
http://lxr.linux.no/#linux+v2.6.36/drivers/staging/rtl8192su/r8192S_firmware.c
it seems that the driver r8192s_usb looks for a firmware file
/lib/firmware/RTL8192SU/rtl8192sfw.bin

but the directory RTL8192SU doesn't exist in Maverick. We first tried copying the firmware file from RTL8192SE:

sudo cp /lib/firmware/RTL8192SE/rtl8192sfw.bin /lib/firmware/RTL8192SU/

after this the wifi stick could detect wireless networks but couldn't connect (the filesize of this firmware is 80976 bytes).
Then we tried a different version of the firmware:

wget http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz
gunzip rtl8192sfw.bin.gz
sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/

with this one the wifi stick could detect wireless networks and connect to them (the filesize of the used firmware is 68368 bytes).

Anyway this discussion it is not relevant for 11.04 since the driver r8912s_usb (RTL8192SU) will be replaced by RTL8172U:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/staging/rtl8712/usb_intf.c;h=f1f0c63e5bbc2dea815eae4b873f59630601d06e;hb=0143832cc96d0bf78486297aad5c8fb2c2ead02a

Thanks a lot, Tony!!!

Copied firmware folder from CD to /lib/firmware/(kernel version/.

Default Ubuntu driver r8192s_usb works perfectly!

We're on Ubuntu Maverick 64bit.

Ubuntu currently wouldn’t load kernel driver automatically, so we added to /etc/modules:
r8192s_usb

To load manually by hand:
sudo modprobe r8192s_usb

Works on Ubuntu Maverick 64bit with following cards:
Canyon wireless LAN USB adapter 150N CNP-WF518N2 (rtl8188su)
Delock USB 2.0 wlan_n Stick 300 Mbps (rtl8191s)

Same problem for me.

* Ubuntu 10.10 32 bit, kernel 2.6.35-24
* USB adapter from EMTEC, ID 0bda:8172 Realtek Semiconductor Corp. RTL8191S WLAN Adapter

The solution of downloading a file from launcpadlibrarian.net suggested by logari81 worked like a charm! Thanks a lot!

BTW: you need to 'sudo mkdir /lib/firmware/RTL8192SU' before copying something inside ;-)

Hello I was trying to connect my RTL8191SU to my home network... After more than 8hours trying it will not try more... I tried days ago ubuntu 11.04 but have problems with X-org and ATI Catalyst Driver... My graphic card is a RADEON 5770, but RTL8191SU worked fine... The problem was that I did not have Control Panel and was not able to enable 3D... Also propietary graphic cards can´t detect my graphic card... This bug of RTL8191SU is there more than a year when I bought new CPU and new wifi-card... I was tryining to do all I read but still can´t make it works...

Have to try this: http://gurrier.wordpress.com/2010/06/18/inexpensive-802-11n-wifi-usb-with-ubuntu-10-04-lucid-lynx/

Can you confirm if it works in ubuntu 64 bit version?? I need a stable linux and last year all went problems... Have to use VM in W7...

I was trying archlinux but still have same problems...

Also I am little noob, Should I install 11.04 and have to fight with ATI drivers and X-org? I am desperate...

Sorry for my english and thanks in advance.

Greetings.

Omg FINALLY IT WORKED IN 64 bit archlinux... Solution is in #35... I don´t know what i did but the file was not in correct path... I had a directory rtlfxxxx.bin and inside the driver.... :(((((((((((((( What a lost of time today...

Thank you for solution :)
