Jammy does not work on wifi for Intel 3165

[John Rose]

Intel 3165 wifi does not work on Jammy new install. Ubuntu's Network Manager sees the router but never manages to connect to it. I've tried the purge of the backport iwlwifi module but that didn't help. I followed the instructions on another post to give diagnostics. They are at https://pastebin.ubuntu.com/p/6tgVfYkmFj/

Some more info:

admin@Server:~$ lspci -nnk | grep 3165

I've just tried 'sudo apt install linux-modules-iwlwifi-generic" and that worked Ok. I rebooted, disconnected Ethernet & turned wifi on. But still get 'SSID connecting' which never finishes and no wifi.

This change was made by a bot.

On Ubuntu Forums it wasted that I try the solutions at https://bugzilla.kernel.org/show_bug.cgi?id=207409. Those solutions are above my pay grade to implement!

[John Rose (johnaaronrose)]

I've tried downloading from https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-7265-ucode-25.30.14.0.tgz, and after extracting the resultant 7265files copying them to similarly named 3165 files and then copying the 4 resultant files to /lib/firmware, rebooting and trying again to 'start' wifi. No joy.

[John Rose (johnaaronrose)]

I've also tried the solution suggested in bug 1406208 (i.e. sudo apt purge backport-iwlwifi-dkms) but that didn't work either.

[John Rose (johnaaronrose)]

I've even tried turning Bluetooth on & off, rebooting after each change. But that didn't help. It just shows my level of desperation!

[John Rose (johnaaronrose)]

I've tried a suggestion from https://ubuntuforums.org/showthread.php?t=2480193 but after rebooting that didn't get wthe wifi working:
echo 'options iwlwifi power_save=0 uapsd_disable=0' | sudo tee -a /etc/modprobe.d/wifihacks.conf
echo 'options iwlmvm power_scheme=1' | sudo tee -a /etc/modprobe.d/wifihacks.conf

[John Rose (johnaaronrose)]

I should have mentioned that the idea for the above fix originated at
https://bugzilla.kernel.org/show_bug.cgi?id=207409

[John Rose (johnaaronrose)]

I've tried the solution for the 7265 chip at
https://bugzilla.kernel.org/show_bug.cgi?id=207409
i.e. using sudo, create a file /etc/modprobe.d/wifihacks
    admin@Server:~$ cat /etc/modprobe.d/wifihacks.conf
    options iwlwifi swcrypt=0
    options iwlwifi power_save=0
    options iwlmvm power_scheme=1
    options iwlwifi uapsd_disable=1
followed by a reboot
But that didn't work

Did you reinstall backport-iwlwifi-dkms package after trying the module options?

[John Rose (johnaaronrose)]

I'm not even sure that backport-iwlwifi-dkms package was actually installed when I did 'sudo apt remove backport-iwlwifi-dkms'. I've just done 'sudo apt install backport-iwlwifi-dkms': resulted in about 30 packages being installed (including ones for compiling kernel), and a new 5.15.0-52 kernel being compiled. wifi still not work after rebooting.
