Can't connect to the internet

I installed Ubuntu on a previous laptop and it was able to find all the drivers needed for me to connect to the internet. But now that I have a 5796, it seems that I am unable to connect to the internet.

I'm pretty much very new to ubuntu and can't seem to figure out how/where I can find linux compatible drivers so I can connect to the internet.

Thank you

 

Go to a terminal.
Applications > Assecories > Terminal
Type 'lspci' and give us the output

 

Hi Thomas. Is there a cheat sheet of these cryptic Linux commands you could point me towards?

 

Here's one. It covers a lot, but also doesnt cover a lot.
Will get you started.
There not very cryptic, lspci=listpci.

 

Thanks. And of course they are cryptic. As are all computing commands until you use them. I did some UNIX systems work back in the early 1980's (VI and all that), but most of my knowledge is in mainframe and Windows. Once taught myself PDP assembler from the technical manual, so figure getting a copy of Ubuntu and a cheat sheet will get me off and running.

Thanks again!

 

If you mean you have a Sager NP5796 then you likely have the Intel 5300AGN 802.11a/b/g/n wireless LAN hardware in your laptop, and that's brand new. Linux driver support for it, is still in development. In this Linux kernel announcement post, and from the Intel Linux WiFi driver project web site, the correct driver support for this hardware will be available in the Linux kernel starting with version 2.6.27.

If you can't wait until you can upgrade your kernel, some Ubuntu users have basically added the necessary driver support by using the compat-wireless project and the Intel 5300 microcode, as outlined in the following steps from this post.

1) Open a terminal window and issue the command to allow you to install the necessary components so you can compile programs on your system. (This is the only distribution specific step, as this is what you need to install on Ubuntu to compile programs);

Code:

sudo apt-get install build-essential

2) You then need to download, extract, and then copy the Intel 5000 series microcode to your /lib/firmware directory. This is accomplished by performing the following steps;

Code:

wget http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-5000-ucode-5.4.A.11.tar.gz
tar xzvf iwlwifi-5000-ucode-5.4.A.11.tar.gz
sudo cp iwlwifi-5000-ucode-5.4.A.11/iwlwifi-5000-1.ucode /lib/firmware

3) Next you will need to download, extract, and then build the compat-wireless code. This is accomplished by performing the next steps;

Code:

wget http://linuxwireless.org/download/compat-wireless-2.6/compat-wireless-old-2008-09-12.tar.bz2
tar xjvf compat-wireless-old-2008-09-12.tar.bz2

3a) Alternately you can directly download the latest compat-wireless-old tarball by going to this section of the compat-wireless download webpage, and clicking on the link for downloading the compat-wireless for kernels <= 2.6.26. You should then extract it with the same tar command as above, replacing the compat-wireless-old-2008-09-12.tar.bz2 with the name of the tarball you downloaded.

4) Before we build the driver we need to edit a config file for adding support for the Intel 5000 series hardware. Perform the following steps;

Code:

cd compat-wireless-2.6-old/
gedit config.mk

4a) Search for the string CONFIG_IWL4965_HT=y, (it should be line 94). Hit enter at the end of that line to insert a blank line between it and the next line, (which should be CONFIG_B43=m), and then add the following line;

Code:

CONFIG_IWL5000=y

4b) Then save and close the file. We can now proceed with the compiling and installing of the driver. This is done by performing the next steps.

Code:

make
sudo make install

5) From that same directory You should now use the compat-wireless project's method for first unloading any existing wireless drivers, and then loading the proper ones.

Code:

sudo make unload
sudo make load

You should now have wireless networking working for your 5300. For a much more detailed and complete documentation on this process of getting and installing the compat-wireless project driver, read the download page at their website.

Good Luck..

 

Perhaps Ubuntu testing?(Intrepid Ibex).
It SHOULD work in it.

 

I happen to have a similar dilemma, except I'm able to connect to the internet through an ethernet connection but am not via any wifi network.

 

What you need to do is go under the network configuration settings and delete everything there, reboot and successfully go on the internets
