Question
I have a toshiba laptop c850, dual core. Toshiba does not provide any driver for Wi-Fi for Ubuntu 12.10. I am currently having problem in using DSL modem, Ethernet and Wi-Fi. Can anyone tell me the solution to this problem?
No correct solution

maybe you will find some information there :

Wireless
A really up to date kernel is required for wireless support, at least 3.5.0 is recommended. Realtek has the Linux drivers available for download but they must be re-complied after upgrades to kernel.
As you commented, you got the Atheros Communications Inc. AR8162 Fast Ethernet Controller. This is some guesswork here because there are several versions of the driver and some people state only one is working for them, I stick with the most popular for now.
First download this file from another machine: https://www.kernel.org/pub/linux/kernel/projects/backports/2013/03/28/compat-drivers-2013-03-28-5-u.tar.bz2
If you have Ubuntu or another Linux distro on your second machine you can use wget to download the file:

Next, use your preferred method (preferably an USB Drive) to copy it to your target machine (Toshiba C850) and use the following commands in a terminal. Make sure you are in the right directory first and use cd to change to the directory where your downloaded file resides.
tar -xzvf compat-drivers-2013-03-28-5-u.tar.bz2
cd compat-drivers-2013-03-28-5-u
./scripts/driver-select alx
make
sudo make install
sudo modprobe alx
If this doesn't work try a reboot first then you can try one of the other versions, I can't tell which will work for you:
