Can't find wireless device on new laptop.

#1 Post by Trick »

Hello.

I have a Lenovo U410 that I can't seem to get the wifi to work on it. It works fine in the latest version of Parted Magic, however.

It should be an Intel Centrino 2200bgn

lspci:

Code: Select all

trick@Trick:~$ lspci
00:00.0 Host bridge: Intel Corporation Device 0154 (rev 09)
00:01.0 PCI bridge: Intel Corporation Device 0151 (rev 09)
00:02.0 VGA compatible controller: Intel Corporation Device 0166 (rev 09)
00:14.0 USB Controller: Intel Corporation Device 1e31 (rev 04)
00:16.0 Communication controller: Intel Corporation Device 1e3a (rev 04)
00:1a.0 USB Controller: Intel Corporation Device 1e2d (rev 04)
00:1b.0 Audio device: Intel Corporation Device 1e20 (rev 04)
00:1c.0 PCI bridge: Intel Corporation Device 1e10 (rev c4)
00:1c.1 PCI bridge: Intel Corporation Device 1e12 (rev c4)
00:1c.2 PCI bridge: Intel Corporation Device 1e14 (rev c4)
00:1d.0 USB Controller: Intel Corporation Device 1e26 (rev 04)
00:1f.0 ISA bridge: Intel Corporation Device 1e57 (rev 04)
00:1f.2 SATA controller: Intel Corporation Device 1e03 (rev 04)
00:1f.3 SMBus: Intel Corporation Device 1e22 (rev 04)
01:00.0 VGA compatible controller: nVidia Corporation Device 1058 (rev a1)
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
04:00.0 Network controller: Intel Corporation Device 0891 (rev c4)
From what I can tell, it looks like there are a lot of intel devices not working properly.

I installed that, per a debian guide i found prior to coming here.

I can verify that it is installed:

Code: Select all

trick@Trick:~$ sudo apt-get install firmware-iwlwifi

IGNORE THIS POST, PLEASE

Have you rebooted after installing the firmware?

Please, post the contents of your /etc/network/interfaces

OK, please, ignore my previous posts.

If you have a look there:

http://wiki.debian.org/iwlwifi#Supported_Devices

You will see that the package firmware-iwlwifi does not contain the microcode for your device in Squeeze. But it does in Wheezy:

http://wiki.debian.org/iwlwifi#supported-wheezy

PCI: 8086:0890 Intel Corporation Centrino Wireless-N 2200
PCI: 8086:0891 Intel Corporation Centrino Wireless-N 2200

That explains why a current distro such as Parted Magic finds your wireless card but an old distro such as Squeeze does not.

The solution is therefore installing the firmware-iwlwifi package from Wheezy:

http://packages.debian.org/search?keywo ... re-iwlwifi

Or from Backports, but I am not sure whether or not it has already been backported.

Good to know ...

I wanted an excuse to use Wheezy. :D

My question is, how stable is Wheezy, exactly?

You don't seem to have much of a choice anyway ... :-)
For me it is very stable. Also not that much of updates anymore.
It often depends on the environment one uses. Been ages i tried gnome or kde, hence not sure about those.

With a good backup-solution you are more than safe (good doesn't mean difficult, au contraire).

Correct me if I am wrong, but I think to remember Whezzy has already been frozen or it is about to be. I am using it in several machines (with XFCE4, which it is supposed to become the default DE) and it is alsolutely stable.

However, you do have an option: You can download and install the Wheezy package in Squeeze and, once your wireless connection is up and running, you can add the Wheezy repos and set apt pinning in order to have that particular package installed from Wheezy so that it can be updated.

I don't think adding newer firmware is going to help if the driver in the kernel does not support it.

There's a squeeze-backports repository with Squeeze-compatible newer kernels and firmware-iwlwifi packages that will get it up and running. The newer kernel will help get a lot of your other devices running. see backports.org

Testing is almost always more stable than ubuntu stable releases... And as it's in a freeze right now leading up to being released to stable it's pretty darn good. Only major problem I had in the last year or so( the install was testing from when sarge went stable) is the 3.5 kernel from the experimental repo trashed the journal on on of my EXT3 drives during a heavy write period, and that wasn't testings fault. As long as you keep your head when dist-upgrading and don't let it remove half the system on the odd times where packages are migrating in you should be fine.

Just wanted to stop by and say I got it working fine with an install of Wheezy.

The only other thing is that now my audio doesn't quite do anything... at all...

Can y'all see anything based on the above lspci?
