Public bug reported:
Summary:
After upgrading to kernel version 7.0 on Ubuntu 24.04, the integrated
Intel Wi-Fi card fails to establish a connection to any wireless
network. It enters an infinite loop of scanning and disconnecting. This
is a regression, as the wireless card connects instantly and works
flawlessly under kernel version 6.18.
Hardware & Subsystem Information:
Network Controller: Intel Corporation Comet Lake PCH-LP CNVi WiFi
Interface: wlp0s20f3
Driver module: iwlwifi
Observed Behaviour:
NetworkManager repeatedly fails the authentication phase.
The system logs show a driver-level handshake timeout:
wpa_supplicant: SME: Authentication request to the driver failed
NetworkManager: Activation: (wifi) association took too long,failing activation
NetworkManager: device state change: config -> failed (reason 'ssid-not-found')
Please check the attached journal.log
Current Workaround:
Putting the laptop into suspend (sleep mode) and waking it up makes the card
connect until the next clean boot.
