I have a Thinkpad L380 with Intel 8265, on which I installed Debian 9 base system (from a netinstall USB stick). I downloaded https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-8265-ucode-22.361476.0.tgz, which had the file iwlwifi-8265-22.ucode, which I copied to /lib/firmware and rebooted the machine.

The output of dmesg | grep iwlfifi has the following lines. (There might be some typos, since Ihad to read it from the laptop and type it here, since iwlwifi isn't working on it, and I can't connect it to ethernet for want of a mini-RJ45 connector!)

firmware: failed to load iwlwifi-8265-26.ucode (-2)
Direct firmware load for iwlwifi-8265-26.ucode failed with error -2

Similarly for -25, -24 and -23. Then

firmware: direct-loading firmware iwlwifi-8265-22.ucode
loaded firmware version 22.361476.0 op_mode iwlmvm
Detected Intel(R) Dual Band Wireless AC 8265 REV=0x230
L1 enabled - LTR enabled
L1 enabled - LTR enabled
wlp2s0 renamed frm wlan0

Looking at many online discussions/blogs discussing similar problems, I tried modinfo iwlwifi | more which gave (the first few line)

filename: /lib/modules/4.9.0-8-amd64/kernel/drivers/net/wireless/intel/iwlwifi/iwlwifi.ko
licence: GPL
author : ....
descrption: Intel(R) Wireless Wifi driver for Linux
...
...
firmware: iwlwifi-8265-26.ucode
...

Where can I find version -26 (or anything above -22)? The discussion https://forums.intel.com/s/question/0D50P0000490P1ASAU/iwlwifi8265-linux-firmware?language=en_US mentions that the drivers are maintained at kernel.org and asks users to contact the support people at kernel.org, but there I could only find -22.

Is there any workaround for this problem?

I am not answering the above question, but here is what I leant to solve a similar problem in a different Lenovo laptop with Intel 3165 wireless card. It has the same firmware as the 7265 (https://www.intel.in/content/www/in/en/support/articles/000005511/network-and-i-o/wireless-networking.html).

I asked the Debian kernel maintainers about this issue: I could only find iwlwifi-7265D-{27,22}.ucode online but the driver was trying to load iwlwifi-7265D-{26,25,24,23}.ucode. One of them replied that versions 26--23 are not "required" and the driver has loaded version 22 successfully. (He replied about the 8265 problem mentioned my question, but I supposed it applied in this case too.) After reading some online discussions about wicd, I looked at its settings (Dropdown Arrow on its GUI -> Preferences -> General Settings -> Wireless interface). The field was empty. I suspect that this had to do wlan0 being renamed as wlp2s0. When I entered wlp2s0 there, I was able to connect using wifi.

  • A strange thing is that I have two laptops running the same debian Linux HOSTNAME 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux one with the Intel 3165 mentioned above and the other Qualcomm Atheros QCA9565. iwlwifi renames wlan0 as wlp2s0 while the driver for the other one does not! Hence wicd was able to see the networks in the laptop with Qualcomm. – Manoj Kummini Apr 30 at 4:53
