Wireless is not working on Toshiba L500 laptop
 
I recently installed FC11 on my Toshiba L500 laptop. After installtion linux is not detecting wireless adaptor. I believe toshiba L500 has realtek RTL8191SE CAN 802.11n PCI-E NIC adaptor.

Can any one help me please?

Could you post the contents of the following commands:
Code:

lspci
Code:

uname -a
Code:

lsmod
Code:

dmesg
Run them as root and post the content to http://pastebin.com please.

i run those commands and sent the results to http://pastebin.com

Erm, you should post here the links to your content so I could take a look at them. :)
EDIT: Nevermind, I found your post. It seems that the driver for your wireless card is missing.
The good news are that Realtek provides a Linux-native driver:
Link for 32 bit
Link for 64 bit

***
Your system MUST be able to compile software in order to complete this guide!
You'll need the kernel-headers package installed in order to compile a kernel module ( the driver ).
I don't know the package names for Fedora, but I think the command
Code:

yum install kernel-headers
could do the trick.
-----
I'm referring to this Ubuntu 9.10 guide on setting up a realtek RTL8191SE

The installation should be similar on your fedora system.
***
Install the driver using the following instructions:

Login as root
Code:

su
Go to the /usr/src directory
Code:

cd /usr/src
Unpack the tarball you've downloaded
Code:

tar xzvf /your/download/location/rtl8192se_linux_2.6.0010.1012.2009.tar.gz
Go to the new directory
Code:

cd rtl8192se_linux_2.6.0010.1012.2009
Copy the firmware for your card
Code:

cp -rf firmware/RTL8192SE /lib/firmware
Build the driver
Code:

make
Note: You may get an error at this stage depending on your kernel. Don't worry about it, the stuff we need is compiled.

Now, we copy the compiled kernel module ( a.k.a. the Driver itself )
Code:

cp HAL/rtl8192/r8192se_pci.ko /lib/modules/`uname -r`/kernel/drivers/net/
Code:

depmod -a
If you wish you may remove the driver folder by using
Code:

rm -rf /usr/src/rtl8192se_linux_2.6.0010.1012.2009

----
Hope this helps and good luck!

Thanks for your help. I tried to run these commands, unzip rtl8192se_linux_2.6.0014.0115.2010.tar.gz and run make command. It showed following message
make: *** /lib/modules/2.6.30.10-105.2.23.fc11.i686.PAE/build: No such file or directory. Stop.
make: *** [all] Error 2

Then i run install command, i got following result
install: missing file operand

During this process i noticed that my laptop got RTL8191SE Wireless LAN 802.11n PCI-E NIC adaptor. i tried to search driver for this adaptor but surprisingly i could not find this driver.

I look forward to hear from you

Cheers

Hello, sonitarunp!

It seems your system is unable to find the path to your kernel source.
Btw, yesterday I had to fix up a Realtek WLAN 8192SE and went to http://www.realtek.com.tw and got a new driver package. Just search for 8191SE and click on the RTL8191SE-VA2 (Software) Link. Then download the new updated package for Linux 2.6.X and repeat the steps above. Also, before starting the process described in my first post, try this
Code:

yum install kernel-devel
. I think this should get you the needed files to build the module successfully. If you get errors in the process, post them here.

Good luck!

Thanks for your help.
I downloaded rtl8192se-VA2 and tried to install it by reading 'readme' file. But it did not work.

Now i first installed kernel devel and then try to install the this but did not get through.

I encountered following errors...............
Command 'make'

make: *** /lib/modules/2.6.30.10-105.2.23.fc11.i686.PAE/build: No such file or directory. Stop.
make: *** [all] Error 2

command 'cp HAL/rtl8192/r8192se_pci.ko /lib/modules/`uname -r`/kernel/drivers/net/'

cp: cannot stat `HAL/rtl8192/r8192se_pci.ko': No such file or directory

I once again appreciate your help.

Cheers

Ok, it seems that the "/lib/modules/2.6.30.10-105.2.23.fc11.i686.PAE/build" for which it is looking is actually a symlink to the kernel source.
If you have installed the kernel-devel package, then this command should be able to take you to the next step:
Code:

ln -sv /usr/src/linux /lib/modules/`uname -r`/build
and retry to build the driver.

Good luck!

A new version of the driver RTL8172 / RTL8192SE / RTL8191SE has been created by realtek. The driver works very well on a Toshiba with standard Ubuntu 9.10 64bit while the previous versions of the driver did not see the network. I know it works on 64bit 9.10 Ubuntu but I don't know if it is a 64bit driver or if it is a 32bit driver fully compatible with 64bit system.

The driver file is rtl8192se_linux_2.6.0015.0127.2010.tar.gz and is 1905119 bytes long. Another version of the same file is 1860920 bytes long but the wifi is working on AC but is not working on battery. Last night I checked the realtek download site but it is an old rtl8192se driver. You should get it from realtek by emailing to realtek support at wlanfae@realtek.com or to roger_liang@realtek.com. I prefer you get it from realtek but I will sent it when you request it by private message.

--- The driver is now available from Realtek download page ---

http://www.realtek.com.tw/downloads/...Downloads=true


The driver works with a simple make + sudo make install + reboot , BUT remember, it has to be recompiled each time the linux kernel changes number.

Note: Make sure lscpi shows RTL8172 at line 02:00:0. If it shows RTL8192, you need the RTL8192E driver.

Solved - Now wireless is working on my toshiba L500
 
Thank you very much for your assistance and guidance.

Now things have changed a bit. I wiped out FC11/14 and installed FC15 on the laptop, in the anticipation that wifi will work, but it did not.

Then,I contacted realtek USA office and requested them to send me the latest driver for RTL8191SE adapter. I followed the instructions and tried to install the drive but again gave the same error. (SEE MY EARLIER POST) missing kernel*****.PAE file.

I contacted them again and attached the error message for their reference. They advised that i need to install kernel header and source. Then I installed kernel header, kernel source called "ketchup-0.9.8-5.fc15 (noarch) and then tried to install the drive once again. Then it gave some error (in short missing "gcc"). Then i installed gcc and run the make command. This time it run successfully and build the driver. Then I run "make install" command, and it worked, finished without any error.

I reboot the laptop, now wifi started working.

I once again thank you all for your effort and support.
