Ubuntu 9.04 can't connect to wifi with Intel Wireless WiFi Link 5100
 
I have only had a few weeks worth of experience with linux, so I'm probably considered a newbie at this but I felt like giving it a shot. I just configured my new Toshiba Satellite A505-S6969 to jaunty. Most of the transition is going well but I'm stuck with a few issues, one of which is getting my wifi to work. Right now I'm working off of an ethernet cable.

Some info that might be helpful:

Like I said, I'm pretty new at this, only minor programing experience. Answers in the simplest terms are best. I do not know if it's a problem with the driver, firmware, etc. Thanks for all and any help

Have you seen this page: http://www.intellinuxwireless.org/ ?

I checked that website and downloaded the driver. I'm a bit puzzled with the installation guide as I'm quite new to this. Can someone put it in plain english?

The iwlagn driver will look for the file iwlwifi-5000-2.ucode using the
kernel's firmware_loader infrastructure. In order to function
correctly, you need to have this support enabled in your kernel. When
you configure the kernel, you can find this option in the following
location:

Device Drivers ->
Generic Driver Options ->
Hotplug firmware loading support


You can determine if your kernel currently has firmware loader support
by looking for the CONFIG_FW_LOADER definition on your kernel's
.config.

In addition to having the firmware_loader support in your kernel, you
must also have a working hotplug and udev infrastructure configured.
The steps for installing and configuring hotplug and udev are very
distribution specific.

Once you have the firmware loader in place (or if you aren't sure and
you just want to try things to see if it works), you need to install
the microcode file into the appropriate location.

Where that appropriate location is depends (again) on your system
distribution. You can typically find this location by looking in the
hotplug configuration file for your distro:

% grep \"^FIRMWARE_DIR\" /etc/hotplug/firmware.agent

This should give you output like:

FIRMWARE_DIR=/lib/firmware

If it lists more than one directory, you only need to put the
microcode in one of them. In the above example, installation is
simply:

% cp iwlwifi-5000-2.ucode /lib/firmware

You can now load the driver (see the INSTALL and README.iwlwifi provided with
the iwlwifi package for information on building and using that driver.)

It is in plain english. Just read it slowly, and SEARCH for terms you do not understand.
Follow the instructions. If you get errors, tell us exactly what they are.

Please tell us the name of your linux distro (you installed it, you should know) and what your kernel version is ( uname -r will tell you )
