iwlwifi produces slow boot since Ubuntu 24.04 upgrade on Intel adapter

[alb1]

As said in title, boot time extends by 60 seconds waiting for iwlwifi.

The Intel adapter is as follows according to lspci :

00:14.3 Network controller: Intel Corporation Cannon Lake PCH CNVi WiFi (rev 10)

And here is the dmesg output pointing to iwlwifi :

[    6.373095] input: HDA Intel PCH HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:1f.3/sound/card0/input28
[   65.517047] iwlwifi 0000:00:14.3: Registered PHC clock: iwlwifi-PTP, with index: 1
[   65.620467] kauditd_printk_skb: 115 callbacks suppressed

What can I try to maybe load another firmware, or otherwise get these 60 seconds of boot back ?

Hello and thank you for your answer.

As it happens, I solved the issue by deleting all remembered Wifi connections that I didn't use, keeping only the one I have at home.

It immediately made NetworkManager load instantly instead of waiting 60 seconds.

Thanks again,

Best regards
