rtl819xU: --->FirmwareDownload92S() -> usb 1-5.4: firmware: requesting RTL8192SU/rtl8192sfw.bin -> rtl819xU:request firmware fail! -> Bus 001 Device 006: ID 0bda:8172 Realtek Semiconductor Corp. -> TRENDnet TEW-649UB Wireless Adapter not working in Ubuntu 10.04 LTS

Please first connect your network card to the wireless router using an ethernet cable (also known as a LAN cable).

In order to gather essential troubleshooting information about your wireless card, please follow this procedure:

Step 1: Open Terminal from "Applications->Accessories->Terminal"

Step 2: Please copy-paste the following command from the https://answers.launchpad.net/ubuntu website in Firefox into the Linux Terminal. Do NOT copy-paste from the Email message into the Terminal, as that will only copy PART of the command. The command STARTS with the word sudo and ENDS with the word restart. So please copy-paste the ENTIRE command below from Firefox into a Terminal, press <enter>, then enter password when sudo asks for password, then press enter again.

Tip: If you have a wheel mouse or 3 button mouse you do not need to type commands into the Terminal. Highlight the command written on the page. Move your cursor anywhere in the Terminal and press the wheel or middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

sudo aptitude update; sudo aptitude install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

Step 3: Please post results (copy/paste terminal output) on this thread. The troubleshooters here need to see the full Terminal output from running the above command.

Here you go:

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

eran@ubuntu:~$ sudo aptitude update; sudo aptitude install hwinfo grep; sudo lshw -C network; rfkill list; sudo iwlist scanning; cat /etc/network/interfaces; cat /etc/lsb-release; lspci -nn; lsusb; sudo lshw -short; uname -a; dmesg | egrep 'ound|irmware|eth|ath|wl|ipw|b43|witch|ndiswrapper'; iwconfig; grep b43 /etc/modprobe.d/*; grep wl /etc/modprobe.d/*; sudo hwinfo --netcard ; sudo /etc/init.d/networking restart

Please try all the suggestions (one by one) in the following bugreport:

https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/594248

In the meantime, I have gained more insight into this issue.

I first suggest running the following command:

sudo aptitude update && sudo aptitude install linux-firmware linux-firmware-nonfree

So make sure both the linux-firmware and linux-firmware-nonfree packages are installed.

Then run the following 2 commands:

wget http://svn.debian.org/wsvn/kernel/dists/trunk/firmware-nonfree/realtek/RTL8192SU/rtl8192sfw.bin

sudo cp rtl8192sfw.bin /lib/firmware/RTL8192SE

I think that the problem is that the firmware file rtl8192sfw.bin is installed in the "wrong place" (by default).

The firmware file rtl8192sfw.bin is installed and located in /lib/firmware/RTL8192SE

However the rtl819xU wireless driver is searching for the firmware file in the directory /lib/firmware/RTL8192SU

Notice the SU at the end of the directory name /lib/firmware/RTL8192SU.

That is why they propose creating a symlink from /lib/firmware/RTL8192SU to /lib/firmware/RTL8192SE (so that the driver can find the firmware file...)

So create a symbolic link using this command:

sudo ln -s /lib/firmware/RTL8192SE /lib/firmware/RTL8192SU

Then reboot and retest wireless.

Hope this helps.

hello,
I think that you found the right partial solution.
As a matter of fact I was not able to connect using this Realtek adapter ( Belkin version ) and the kernel driver (staging).

I had for two months the three firmware files contained in "RTL8192SE" ( copied in "RTL8192SU"), but never gained a single connection. So I thinked to some problem coming from "staging" driver, none of my attempts to solve this problem has worked.
This night I have read your hint, downloaded this firmware file (rtl8192sfw.bin) and discovered that the one I already ( from "RTL8192SE" and downloaded from svn.debian... ) ) have the same name but the size differ !!!

The 8192SE is about 80Kb while the 8192SU is about 68Kb.
I have simply replaced the firmware with the one just downloaded, now the staging kernel drivers is fine on 32 and 64bit os
