Ubuntu Question - How To Reinstall Wireless Drivers?

For an Acer Aspire one?

I was using modprobe I believe.. and one day all wireless options were gone.

How do i get them back?

Please cut-paste the procedure..

The Aspireone Ubuntu faq has 2+ wireless adapters listed and its gotten very unorganized.

Any help would be appreciated..
thanks

After an update changes your kernal, you need to recompile the wireless drivers for the new kernal. Fret not, it is easy. I have pasted the steps below. To accomplish this task, you will need to plug your aspire one directly into a network to allow you to download the drivers.

Code:

WIRELESS:

There are two different ways of configuring the wifi hardware, using either madwifi drivers, or wrapping Windows drivers with ndiswrapper. If you have troubles with one method, try the other.

Now we need to disable the hardware drivers that Ubuntu tries to use before the ones we make will function. So go to System -> Administration -> Hardware Drivers and uncheck everything. It should prompt us to reboot, so lets do it now.

We need to grab the wireless driver, and the things we need to build it, from a terminal:

mkdir source
cd source
wget [url]http://snapshots.madwifi.org/madwifi-hal-0.10.5.6/madwifi-hal-0.10.5.6-r3835-20080801.tar.gz[/url]
tar -xzvf madwifi-hal-0.10.5.6-r3835-20080801.tar.gz
cd madwifi-hal-0.10.5.6-r3835-20080801
sudo apt-get install build-essential linux-headers-$(uname -r)

And we build and install:

make
sudo make install
sudo modprobe ath_pci
