Bug Description

SRU Justification for Lucid for linux-backports-modules-2.6.32:

The change merely adds the 6050 iwlwifi firmware to the package. The drivers already in the package should be sufficient to utilize the firmware correctly. There is no regression potential because the file did not exist before.


Wireless Controller: Intel WiMAX/WiFi Link 6050 series (Kernel module iwlagn.ko)

Intel wireless controller can be detected, driver is loaded, but clicking network manager shows no access point. Our office has at least 2 APs as I can see them using other systems. Installing linux-backports-modules-karmic did not fix things, nor did installing the 2.6.33 kernel from the PPA. Once I've installed either the backports or the new kernel, there appears to be a missing microcode/firmware issue, specifically for "iwlwiki-6050-4.ucode".

Steps to Reproduce:
1. Boot the system
2. Click network manager
3. Look for available AP for wireless connection

Expected result:
Available APs are listed, select the best one to make connection.

Actual result:
No AP can be seen.

I cribbed most of this bug description from bug #496496.

As mentioned, Intel's wireless driver refers to missing iwlwifi-6050-r.ucode which is microcode for Intel 6050 series, but for some reason it is not available from Intel's and as I know was never available there. As this is the only way (would be glad to be wrong) to get this microcode I'm afraid we should just be patient and wait for it.

Roman Andriadi (narn) wrote :

Shurely, iwlwifi-6050-r.ucode should be read as iwlwifi-6050-4.ucode. BTW, this concerns not only 4th version of ucode. No microcodes for 6050 series at all was ever provided by Intel.

I just tested Lucid latest daily, and wireless wasn't working on a Lenovo Thinkpad Edge, using Intel WiMAX/WiFi Link 6050 series, id 8086:0089.

According to the Debian Wiki, the current iwlagn driver should work.
It seems the microcode for the 6000 series is the one to use.

Current iwlagn driver should work only with appropriate microcode and it's not the one for 6000 series.
At this moment iwlwifi driver in the latest 2.6.32-9 kernel (from debian sid) requres specific 6050 series microcode up to 4th API version. It should not work with 6000 microcode (and it does not). Latest kernel from has no changes concerning 6050 microcode since 2.6.32, therefore it also does not really support 6050 series cards.

The Linux WiMAX software for the 6x50 series is still incomplete; the
kernel drivers have been enabled ahead of time, but the user space
support, including the firmware file is still in the final stages of

Availability time is still TBD, but should be sooner than later.

Just a note on why I marked #537814 as a duplicate: the 6250 card is a 6050-series card.

Once the firmware is released by Intel, how much packaging work is likely to be involved to get this pushed out to the repositories? I'm not that up to speed on Ubuntu packaging, but I'm willing to learn / pitch in.

David Strauss (davidstrauss) wrote :

@KB1JWQ The packaging work should be minimal. It seems like the kernel module just needs the firmware blob without any other change.

"Availability time is still TBD, but should be sooner than later." - this is now a month old and this USB wifi dongle is getting really annoying :-P

Roman Andriadi (narn) wrote :

Yes, it looks like there is such driver, and be sure it is already present in repos. But there's still no firmware for 6050 series WiMAX cards. That is what we're waiting for, not the driver.

Corey Quinn (kb1jwq) wrote :

Right, I get that. But what I saw that struck me as "new" was the iwlwifi-6000-4.ucode firmware bundle; I haven't seen it before, and I THINK that it's being referred to in the 6250 (and other) drivers as the appropriate firmware blob in the latest development snapshots.

Am I wrong?

The -6000 is different from the -6050. I even tried renaming the
-6000-4.ucode file to -6050 to see if it would work, and got an error like
"microcode loading failed". So we still need Intel to produce -6050
firmware (aka microcode).

6000's firmware is for other adapters. It's for 6000AGN series cards, that are WiFi adapters only.

Florian (exameme) wrote :

hm. i guess we'll have to wait a bit longer:

Please note that firmware for 6250 hardware (also referred to as 6050 series) is not available yet. When it becomes available we will announce it on the linux-wireless mailing list and also post it on this webpage under the Downloads section. We hope to be able to make this announcement some time in the third quarter.

is what it says on since recently.

This is what they added to the page when I complained that website claims it's supported. I don't think this is precisely the kind of response I would like to have.

Florian (exameme) wrote :

*** somewhat OT... sorry! ***

i know this is actually fairly ot but at least related in so far as i have to deal with it because of the missing firmware and others here probably have too...
can anyone recommend any _small_ usb wifi dongles that do g/n? i bought 2 different one that are both ralink based and cannot get them to play nice with wpa.


David Strauss (davidstrauss) wrote :

@fijal I'm not aware of any place on the Intel website that says the 6050-series Wi-Fi adapters are supported on Linux. I've only see support for the 6000-series ones.

fijal (fijal) wrote :

Here you go:

It clearly says "-Intel® Centrino® Advanced-N + WiMAX 6250" as an item. Since it leads to intellinuxwireless website, maybe you can figure out that it does not work, but it was not completely trivial before they added info that it's not supported (difference between marketing names on one site and development names on other site does not help folks like me).


Erik Wahlstrom (edub) wrote :

In agreement/solidarity with fijal on this one. I remember checking for Linux support when I configured my T510 and coming to the conclusion (based on the information available on Intel's site) that the 6250 card was supported.

It's now several months after the product has shipped and we still do not have the proper firmware available for this Intel hardware. This is piss-poor and can't help but undermine Intel attempts at convincing the community that it treats Linux as a first-class environment.

I communicated my unhappiness on this issue to Intel via the
<email address hidden> address offered on the page.
Perhaps others should do so too (politely, I suggest), focusing on damage
to the Intel brand, loss of revenues to WiMAX services, etc.

Roman Andriadi (narn) wrote :

> damage to the Intel brand
They surely know this, but either it's really diffulcult to complete this firmware or nobody cares. And it's most likely the last. It's buisiness, and if opensource does not make money for Intel - they doesn't care at all.

I have just succeeded in running the 64-bit WinXP driver from Intel under a modified trunk version of ndiswrapper. No data on stability or speed just yet. I will submit my patches to ndiswrapper (2 extended APIs from XP SP2 have to be stubbed out or the driver won't load) and post updates here as things develop.

My testbed system is a Dell Studio 1557 (brand new -- delivered less than a week ago); lspci says that it's got a 6050 series adaptor rev 3.5, device ID 1321. I run Ubuntu Lucid, kernel 2.6.32-21

One consistent problem thus far: after a disconnect, ndiswrapper has to be unloaded and loaded back with modprobe to connect again. Doesn't matter if the disconnect is explicit or caused by sleep/resume. Careful analysis of the logs didn't yield much: no specific errors; sometimes there's nothing from wpa_supplicant at all and sometimes wpa seems to proceed normally but DHCP requests are never responded to. Maybe transmitter gets turned off for good?

Intel has released microcode for 6250 on 02.06.10 (Wifi only). Seems to work ok so far. and apparently it's included in kernel from 2.6.34.

Benn (benn-blessing) wrote :

Is it possible to add it as an update? It's just a single file that sits in firmware folder.

The existing kernel module will pick it up.

So.. How come adding the firmware makes the adapter work? Not perfectly I readily agree (it seems hit and miss whether it actually connects) but non-functional it isn't.

So I'll need to upgrade to Maverick then?

The iwlagn 2.6.32 driver support for the 6050 series of cards in Ubuntu 10.04 LTS is a skeleton driver that may work for users but is not supported by Ubuntu because we couldn't test it before release, among other reasons. However, we do have the linux-backports-modules-wireless package which will contain the 2.6.34 version of the iwlagn driver when the 2.6.32-22.15 version releases. It is recommended that users install this package for support for these cards.

However, the package as it stands right now does not have the firmware in it yet. I have added a task to this bug for adding the firmware to it.

I know this fix is not supported officially, but I thought I'd at least report that upgrading to the packages in lucid-proposed caused the laptop to run in low graphics mode when booting the new kernel that uses the fix.

The laptop was running the Nvidia proprietary driver for a NVS 3100 before the fix. I went ahead and installed every update in lucid-proposed, but still am stuck in low graphics mode.

If things are broken due to a lucid-proposed package, you should open a bug against the package that caused the issue. Likely this is the "nvidia-current" package that is causing you issues.
