Public bug reported:
== Summary ==
Intel Killer Wi-Fi 7 BE1750 stopped working after upgrading from kernel 6.14
to 6.17.
WiFi works perfectly in Windows and was working on Ubuntu until approximately
1 month ago.
== Hardware ==
- System: Alienware (Dell)
- BIOS: 1.11.0
- WiFi: Intel Corporation Wi-Fi 7 BE1750 [8086:272b] (rev 1a)
- Subsystem: Rivet Networks [1a56:1774]
== Software ==
- Ubuntu 25.04 (Questing)
- Kernel: 6.17.0-8-generic
- Firmware: iwlwifi-gl-c0-fm-c0-101.ucode (version 101.6ef20b19.0)
- Driver: iwlwifi + iwlmld
== Error ==
The WiFi adapter fails to initialize with ADVANCED_SYSASSERT error:
iwlwifi 0000:82:00.0: 0x2010210B | ADVANCED_SYSASSERT
iwlwifi 0000:82:00.0: retry init count 2
iwlwifi 0000:82:00.0: Device is not enabled - cannot dump error
No wlan interface is created. rfkill shows no WiFi device.
== Troubleshooting Attempted ==
- Disabled Wi-Fi 7 mode: options iwlwifi disable_11be=1 (no effect)
- Tried older firmware v100 (same error)
- Installed linux-modules-iwlwifi-generic (no effect)
- Disabled power save: power_save=0 (no effect)
== Regression ==
WiFi was working on kernel 6.14.x approximately 1 month ago.
This is a regression introduced in kernel 6.17.
== Expected Behavior ==
WiFi should initialize and create wlan0 interface.
== Actual Behavior ==
Firmware crashes during initialization, no wireless interface created.
