No WIFI or LAN on Ubuntu 12.04 or 12.10 Live CD/USB using Toshiba qosmio x870

Question

I recently had issues with secure boot and couldn't boot the Live CD/USB but after disabling secure boot, I was able to 'TRY UBUNTU'. My currently problem is that I can't access WIFI or LAN from either Ubuntu 12.04 or 12.10 Live CD/USB which I do from Windows 8. Also, the wireless button is able to turn on and off the wireless LED but doesn't find available WIFI. Please, what should I do to get both WIFI and LAN working on Ubuntu using Toshiba qosmio x870?

Answer 1

The solution provided in this link Drivers for Realtek wireless module for Toshiba by @izx solved the wireless problem. Now I'm able to connect to my home wireless and can also see other wireless around from Ubuntu Live CD/USB.

All you need to do is open a terminal, and type/paste one line at a time the following:

sudo apt-get update

sudo apt-get install build-essential linux-headers-generic linux-headers-uname -r

wget -O- http://dl.dropbox.com/u/57056576/DRIVERS/REALTEK/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012.tar.gz | tar -xz

cd rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012

make

sudo make install

sudo modprobe rtl8723e

Update: To get my Atheros AR8161 (LAN) working, I did the following:

apt-get update
apt-get install linux-generic-lts-quantal

After updating my kernel, my WIFI stopped working. Here is what I did to get it up and running.

For kernel 3.5 and above, use the newer driver version:

wget -O- http://www.liteon.com/UserFiles/driver/Module/Network/WLAN/RTL/rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012.tar.gz | tar -xz

cd rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012

make

sudo make install

sudo modprobe rtl8723e

If it doesn't work then you need to remove rtlwifi because the version that comes with the lower kernel is different from the one the newer rtl8723e is compiled against. That way, the new one will work!

Hence, do the following:

rmmod rtl8192se and any other rtl that was compiled with the previous kernel.

rmmod rtlwifi

Finally, execute

sudo modprobe rtl8723e

and your wireless should be up and finding all wireless around.

Answer 2

OK, first answer :) You have an Atheros 8161 - Try the following ! (original post is http://ubuntuforums.org/showthread.php?t=2088179 )

(You'll need an online machine to get the driver to a USB stick and the ubuntu CD inside the x870)

on the working machine with internet:

wget -O- http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-2012-07-03-pc.tar.bz2 or just get the file with a browser.

then copy that compat-wireless*.tar.bz2 to a usb drive

insert the install cd & usb stick into the machine that needs the drivers and run in terminal (use your thumbdrive in place of USBTHUMB):

sudo apt-get install build-essential

cd /media/USBTHUMB/

tar -xvf compat-wireless-2012-07-03-pc.tar.bz2

cd compat-wireless-2012-07-03-pc

./scripts/driver-select alx

make

sudo make install

Hope this helps.
