Bug Description

- WIFI is active, and I can see available networks, e.g. with iwlist wlp3s0 scan
- However, connecting to a network (with the GUI) fails: after entering credentials (for a password protrected WPA2 network) it tries to connect for a few seconds but then asks for a passphrase again .. and again ..
- Also the problem is not the GUI, the exact same behavior is shown by nmtui

Checking the output of NetworkManager in /var/log/syslog we can see that the association is the one that fails:

sudo cat /var/log/syslog | grep "(wlp3s0)" | sed 's/.*device //'

Checking the journal and logs I can not find any errors or warnings, but I noted that iwlwifi seems to have a debug mode activated.

Hi, could you give some more details, what (kernel/firmware versions) was working, what is not? Could you test following combinations:

1. mainline v5.4-rc5 kernel[1] + linux-firmware HEAD[2]

2. bleeding edge backport-iwlwifi-dkms[3] + linux-firmware HEAD

3. linux-image-oem-osp1 kernel + linux-firmware HEAD

Please paste dmesg output for each of above tests.

Thank you for your suggestions, You-Sheng Yang.

Which kernel/firmware version worked?
-> the default Ubuntu 19.04 kernel and firmware. I never installed a kernel or firmware from external sources and all minor updates that were available worked just fine. What also worked: all other versions of Ubuntu I used on my laptop, at least 18.04 and 18.10 too, most probably I also used 16.04 (not sure).

Which kernel/firmware does not work?
-> The versions at the release of Ubuntu 19.10 (on the .iso images) and also the latest update (5.3.0-19-generic).

An important detail could be, that when I boot Ubuntu 19.10 with the old kernel still installed from 19.04 the same behavior can be seen.

Update: In my case WIFI works again after disabling 802.11n. I added the option 11n_disable=1 to /etc/modprobe.d/iwlwifi.conf - now it looks like this:

# /etc/modprobe.d/iwlwifi.conf
# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system. When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac8021
options iwlwifi 11n_disable=1

See also https://wiki.archlinux.org/index.php/Network_configuration/Wireless#iwlwifi (the iwlwifi parameters apply to Ubuntu too and Arch has great documentation )

Markus, if neither dkms nor latest mainline kernel works for you, then we'll need to file an upstream bug to https://bugzilla.kernel.org/buglist.cgi?component=Wireless&product=Networking&resolution=---

Since my upgrade today to 19.10 I am affected by the same bug, but with different hardware

$ lspci -nnk | grep Network -A2
00:14.3 Network controller [0280]: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30)
Subsystem: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:0034]

Tried backport-iwlwifi-dkms and the old kernel, none of which helped, so I'm using the 11n_disable workaround as well for the time being.

@Bernhard, you have a different card, it's not the same bug. Please file a separate bug instead.

@Markus, I found a model with Intel Wireless 7265 but with subsystem id [8086:5410]. The adapter works out-of-box with Eoan generic kernel 5.3.0-24-generic, and yes, and I also got endless auth retry with backport-iwlwifi-dkms 7906-0ubuntu3. So you might want to remove backport-iwlwifi-dkms as you don't really need it. backport-iwlwifi-dkms version 8042-0ubuntu2 from Focal also works well with this piece of hw.

Changed in backport-iwlwifi-dkms (Ubuntu):

Same issue with my Intel Wireless 8260
Upgrading from 7906 to 8324 in Ubuntu 18.04 fixed this nasty bug for me.
I use now this and be happy
