Need support for Intel new wifi module 9462NGW

Need support for Intel new wifi module 9462NGW

[Chris Chiu]

Hi,
    We just have the Intel new WiFi module 9462NGW from Acer and tried
to verify if it works on the latest linux kernel. Unfortunately it
seems not even detected because the PCI ID seems unknown to the
iwlwifi driver. Then I add the following line to
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
iwl_hw_card_ids
{IWL_PCI_DEVICE(0x31DC, 0x02A4, iwl9460_2ac_cfg)},

dmesg shows the following

[   12.994422] iwlwifi 0000:00:0c.0: Direct firmware load for
iwlwifi-9260-th-b0-jf-b0-33.ucode failed with error -2

[   12.994479] iwlwifi 0000:00:0c.0: maximum version supported:
iwlwifi-9260-th-b0-jf-b0-33



I'm not able to find these missing files in linux-firmware.git and any
other possible place. What's the status of supporting this 9462NGW?
Please let me know if any more information required. Thanks

Chris

Unfortunately we have not published the firmware for this NIC yet. 
I'll try to get an approval to publish it today (or latest by the end
of the week) and I'll let you know.

Yes, I published it last Thursday.  Sorry, I was in such a hurry that I
 forgot to tell you about it.

You can find it here:

https://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/linux-firmware.git/plain/iwlwifi-9260-th-b0-jf-b0-33.ucode?id=f132386b542b52ade0416ecb6cb7aef426f5d175

Hi Luca,
    I just tried the firmware but seems still something wrong. dmesg

Hi Luca,
    Any suggestion for the "Failed to start INIT ucode: -110" issue
for the firmware?

We are investigating this now.  This seems to be related to the secure
boot key not being valid...

I'll let you know when we progress on this.

There were a few problems which should now be fixed.  We published new
firmwares in our linux-firmware.git tree[1] and also made some fixes in
the driver[2].  Please update your system accordingly and let me know
if it works for you.

Thanks!

Hi Luca,
    Thanks for your patch and updated firmware. The driver can
initialize w/o error now. However, it always fails on ip-config after
4-way handshake complete. I have to mention that I removed the field
".soc_latency" in all new iwl_cfg you added in
https://patchwork.kernel.org/patch/10059875/ to remove compile error
based on the linux mainline 4.14.
    I don't know whether if this causes the problem. Do you need me to
do anything for more information?

Chris

That was my fault, I forgot to include one file in my commit.  I have
sent v2 of the two last patches to solve the problem.  Can you try
them?

The problem you're seeing could be related to that, because we use a
bit longer wait period for HW stabilization with integrated devices. 
And if you remove it, you may encounter random problems...

Re: Need support for Intel new wifi module 9462NGW

[Luca Coelho]

Here are the links to v2 of the last two patches, please try with these
instead (keep the first one that you already have):

https://patchwork.kernel.org/patch/10060837/
https://patchwork.kernel.org/patch/10060839/

Hi Luca,
    Thanks for your quick response. I  tried your v2 patch but things
remain the same. The signal strength and scan results seems nothing
wrong but still fail to get ip from DHCP server. Please let me know
what I can help here.

Can you provide the dmesg output and trace-cmd logs as explained here?

Hi Luca,
    Here's the dmesg log of the fail case on DHCP.

Hi Luca,
    Some more observation I want to point out and maybe you can suggest.
After your v2 patch and the latest firmware. I'm pretty sure there's no problem
on my 9462NGW module to associate to an AP (4-way handshaking complete)
dmesg in https://gist.github.com/mschiu77/1fe1f5128f1c49a93055ce23976c09b5
here also shows
[   59.338785] wlp0s12f0: associated

Then I do air sniffer with my mac book air and only dump DHCP packets in
https://gist.github.com/mschiu77/677b5fbfdea0fea2eda4a36a84bcac8e

As you see, 4 DHCP Discovery here but no response. I do the same thing on
the other laptop to associate to the same AP SSID, there's no problem.

And yet another interesting thing is, every time I was trying to associate
The ifconfig always give me a totally different ether address. I log 5 times in
https://gist.github.com/mschiu77/54169d52b9fcf205d5c26752988f8a3d

The read HW address should be 34:13:e8:6f:34:25 and it's also true in tcpdump
log.

I think maybe it's related. Can you suggest anything that I can try?

Chris

Hey Chris,

Thanks for the update and sorry for the delay.  I'll take a look into
this in the coming week, there's probably something missing in the
driver that is causing this issue...

Re: [linuxwifi] Need support for Intel new wifi module 9462NGW

[Chris Chiu]

Hi Luca,
    I got another machine which has Intel 9461NGW (31dc:0264) and
stuck at the same problem. I can't see the DHCP response on the air.
However, the router does respond to the DHCP discover. Please check
the following tcpdump here. The 9461's mac address is
60:f6:77:9a:f4:ed
https://gist.github.com/mschiu77/8f613ba6e3c41a3bd5206f1e903b0bbd

    Then I go to AP and do tcpdump, I can still see the DHCP reply
packet on the corresponding interface. Don't know why can't I see this
packet on the air? maybe wrong channel?

Re: [linuxwifi] Need support for Intel new wifi module 9462NGW

[Chris Chiu]

Hi Luca,
    I think the problem is not missing DHCP reply. I installed tcpdump
on the machine with Intel 9461NGW and start monitoring on the wlan
interface.
The result is following
https://gist.github.com/mschiu77/f4cc14ddae6adf137da15675cca59b30

I also attach the ifconfig result at the end of the above url. Hope
this can help a little.

Hi Chris,

Sorry for the delay.  We've been testing this internally, but couldn't
reproduce it at first.  The problems seems to be with the firmware that
we released.

I'll provide you an update today or latest by Monday next week.

Hi Chris,

We found a patch that was missing from upstream and causes data
corruption on secure associations:

https://patchwork.kernel.org/patch/10088939/


Can you try to apply this patch and see if it fixes the problem you are
having?

Hi Luca,
    I applied https://patchwork.kernel.org/patch/10088929/ and
https://patchwork.kernel.org/patch/10088939/, I can access internet
thru 9461/9462NGW now. Thanks so much.
