Set up Toshiba L650 laptops after ubuntu installation

This article explains how to set up device drivers after installing Ubuntu in Toshiba laptops. Most probably Ubuntu will not support LAN, WiFi, Bluetooth and in some systems, anomaly in working of fan, battery are reported. Some of my problems like LAN setup, WiFi and Bluetooth have overridden and my battery is still showing some problems. I hope these instructions will be helpful for Toshiba Laptop users. Note that this article is a "how I did" type article rather than a "how to".
Some models of Toshiba Satellite are preloaded with Windows and some are not. In pre-installed models, try to make the system dual boot. There are a lot of tutorials for that and in Ubuntu, this is pretty easy compared to other distros. Anyway, I assume you have Toshiba system with a fresh Ubuntu installed. I used Ubuntu 10.04 LTS on by Toshiba L650-i5310.
Setting up Ethernet
My ethernet card was from Atheros Communications. A driver for Atheros is available from http://linuxwireless.org/download/compat-wireless-2.6 . Download and unzip the file. Then in terminal, cd into that folder. Then type the following code:

scripts/driver-select atheros
make
sudo make install

Then reboot the system.
Setting up Wireless
My Wireless LAN card was from Broadcom Corporation. The driver is readily available from ubuntu repository.

sudo apt-get install bcmwl-kernel-source
echo wl | sudo tee -a /etc/modules

Reboot the system.
Setting up Bluetooth
In bluetooth, I did nothing in Ubuntu and I installed a bluetooth driver from Toshiba in Windows 7. After that incident, my Ubuntu also start detecting bluetooth adapter and don't know how this happened.
