Does ubuntu supports Intel WiFi Link 5300 (AGN) network card?

[svaret]

Also, maybe my problem should be made a new thread since it is about other hardware.

[pytheas22]

Thanks for the information about the card name. I found this thread, which explains how to make it work. It's a little more complicated than I thought, but it should still be possible. Basically there are four steps:

1. upgrade your kernel to 2.6.30 (apparently older kernels don't support this device)
2. compile the qcserial module against the 2.6.30 kernel
3. install the gobi-loader utility to load firmware for the device
4. use wvdial or NetworkManager to connect to your network

Although this may sound hard, it shouldn't really be that bad as long as everything works as expected. The one thing I will warn about, however, is that updating your kernel could possibly have unexpected consequences, so please make sure you back up everything important on Ubuntu.

To get the kernel upgraded, run these commands (you will need to be connected to the Internet first):

wget http://mirrors.kernel.org/ubuntu/pool/main/w/wireless-crda/wireless-crda_1.7_i386.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc4/linux-image-2.6.30-020630rc4-generic_2.6.30-020630rc4_i386.deb
sudo dpkg -i wireless-crda_1.7_*.deb
sudo dpkg -i linux*.deb

If you receive any error messages, please post them here. If there are no errors, reboot your system, and you should be in the new kernel. To check, post the output of the command:

uname -r

Once you get this far, we can move on to the next steps.

Also, the internal wireless card doesn't seem to be working because it's disabled using switch, according to the 'dmesg' output. This usually means there's a button or software switch (like Function+F2) that you need to toggle in order to turn your wireless on.

hi, i have kernel 2.6.29, i compiled latest compat-wireless release and in /lib/firmware i have both firmware (*.1.ucode
and *.2.ucode).

sudo modinfo iwlagn

why i can't use iwlwifi-5000-2.ucode?

[pytheas22]

biasquez: I don't know enough about iwlagn to know why it doesn't want to use that firmware file. But is there a problem with your wireless as it stands now? What is the device ID (XXXX:XXXX) of the card?

sometimes, network is slow and i must reset wifi connection.

[pytheas22]

biasquez: there could be several different reasons that your connection becomes slow, and I think it's unlikely that the firmware is the problem. The next time the connection becomes slow, please open a terminal, run the following commands and post the output:

lspci -nn
dmesg | grep -e iwl -e wlan
dmesg | tail -50
ifconfig wlan0
iwconfig wlan0

Also, do you notice a pattern in the behavior? Does the connection become slow when you're downloading large files or when you visit certain websites, for example? Or does it seem random?

Thanx for your quick reply. /Lasse

Installing the kernel I got this

Sorry that didn't work. Please try running this; it should solve the dependency:

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30-rc4/linux-headers-2.6.30-020630rc4-generic_2.6.30-020630rc4_i386.deb
sudo dpkg -i linux*.deb

This may take some trial and error, but we'll get there eventually...

Pytheas, you helped me a while back in this thread by getting my drivers installed correctly. Before I was having random disconnects. That being fixed, I still have disconnects only this time I've narrowed the cause down to trying to play a large movie across the network from my NAS. So instead of being random, they occur when I do something.

I've run your diagnostic commands here:

Can you help please?

[pytheas22]

SteveONCSU: I think you're suffering from the bug reported here, since you're using the iwl driver and see the same line in dmesg about ""AP denied association (code=12)." Towards the end of the bug report (this comment), someone mentions that changing router speeds seems to help. Please give this a try.

You could also try connecting with wicd instead of NetworkManager. I don't know if it will help, but it can't hurt.

If none of the above helps, you can try compiling the wireless driver using the latest source code by first going to http://linuxwireless.org/download/compat-wireless-2.6/ and saving the file compat-wireless-2.6.tar.bz2 to your desktop, then running these commands:

sudo apt-get install build-essential
cd ~/Desktop
tar -xjvf compat-wireless-2.6.tar.bz2
cd compat-wireless*
make
sudo make unload
sudo make load
sudo make install

Then reboot for the new driver to take effect.

Please let me know if any of this helps; if not, we can try other things.

Also, is it only with one particular that you notice the crashes, or is it with any large file stored on your NAS?
