Ubuntu 10.10 and Intel 6230 Wireless Card

[GeraldNunn]

I just bought a new computer and it comes with the Intel 6230 wireless/bluetooth combo card. I'm trying to get wireless working on this laptop in Ubuntu 10.10 (64 bit) but am not having much success. I installed linux-backport-modules for Meerkat but that did not get the card working. Here is the output of lspci -k:

Any ideas on how to get this going?

With the backport package installed, I see the following in dmesg:



[ 7.608499] iwlagn 0000:04:00.0: request for firmware file 'iwlwifi-6000g2b-4.ucode' failed.
[ 7.608555] iwlagn 0000:04:00.0: no suitable firmware found!


Anyone know where I can get this file as I'm having a hard time finding it.

[GeraldNunn]

I tried downloading the natty beta to see if it had the right firmware file but no luck. I know this works with Natty but I would prefer not to upgrade at this time so any help would be greatly appreciated.

You can normally download Intel wifi firmware from Intel Linux Wireless (http://intellinuxwireless.org/) but they appear to be down (http://www.downforeveryoneorjustme.com/http://intellinuxwireless.org/)

Thanks, I had a look and problem is they have the version 5 firmware (iwlwifi-6000g2b-5.ucode) instead of version 4 (iwlwifi-6000g2b-4.ucode). I just did a quick check by downloading and renaming the file but the driver complains about the newer firmware version.

[jawilljr]

I couldn't find your firmware either...the only thing I would suggest doing is to download and install either the latest bleeding edge compat-wireless drivers (http://wireless.kernel.org/en/users/Download) or the latest stable drivers from compat-wireless.

They are easy to install... just untar the file and change to that directory and do a "make" the "sudo make install" the reboot.

Hope this helps.

Hello,
you can download the latest Firmware from Linux Firmware-Git
http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=tree

Klick on "snapshot" in the upper left corner.

But the new driver from Compat-Wireless recently dont't work with Kernel 2.6.35-*. No Problem with Kernel 2.6.32-* and Lucid.

But the new driver from Compat-Wireless recently dont't work with Kernel 2.6.35-*. No Problem with Kernel 2.6.32-* and Lucid.Below is my uname -r


2.6.35-28-genericAnd the version of compat-wireless I am running is:


compat-wireless-2.6.38-3-nsI even downloaded and installed the latest bleeding edge last night...but reverted back to stable.

So yes they do work with Kernel 2.6.35-*.

Also compat-wireless was the only way could get wireless N at 5ghz.

Great

Check in addition ...

cat /etc/modprobe.d/intel-5300-iwlagn11n.conf
Option should be

options iwlagn 11n_disable=0

[jawilljr]

I actually commented that line out... got me wireless N but no 5 ghz... until I compailed and installed compat-wireless.

Below is my iwconfig on my laptop.

Thanks everyone, I got it working with the bleeding edge version and specifying the iwlagn driver before make. I tried the compat-wireless-2.6.38-2.2-ns version, which is what is available to download in stable releases, but it didn't seem to install the iwlagn.ko driver in the updates directory for some reason.

Both, Router and WLAN-Devive must support two transport streams (MIMO) to achieve this transfer rate. The Intel Card do, but your Router also?

The router must have at least two antennas as a first indication. Device-type and manufacturer of your WiFi-Router?

Do a scan to check out whether the radio channel is free

sudo iwlist wlan0 scan

[jawilljr]

Device-type and manufacturer of your WiFi-Router?lspci:

Router Linksys E3000.
Your Router can. Three Transponder, and three Antennas are build in. Check the Channels as described.
