I applied it on top of mainline (7.3-rc6). I was having issues with my new company laptop for a few weeks. A Dell Pro 14 Plus PB14250, with BE200 Series Wi-Fi 7 (00:14.3) Tested-by: Rafael Passos More details below: Before, this would loop for usually long times, or until I reloaded the driver: ``` [ 349.794606] wlp0s20f3: disconnect from AP $AP_MAC for new auth to $MAC [ 349.899518] wlp0s20f3: authenticate with $MAC (local address=3D$LOCAL_MA= C) [ 349.900258] wlp0s20f3: send auth to $MAC (try 1/3) [ 351.906522] wlp0s20f3: send auth to $MAC (try 2/3) [ 353.922497] wlp0s20f3: send auth to $MAC (try 3/3) [ 354.900727] wlp0s20f3: aborting authentication with $MAC by local choice= (Reason: 3=3DDEAUTH_LEAVING) ``` With the patches applied, I still got a few disconnects, but they were imperceptible. I only know abour them because I was keeping an eye on my logs (AKA `dmesg -w | rg 'wlp|iwl|auth|reason' `). Example disconnection log with the patchset applied: ``` [ 341.720214] wlp0s20f3: disconnect from AP $AP_MAC for new auth to $MAC [ 341.802793] wlp0s20f3: authenticate with $MAC (local address=3D$LOCAL_MAC= ) [ 341.803277] wlp0s20f3: send auth to $MAC (try 1/3) [ 343.820077] wlp0s20f3: send auth to $MAC (try 2/3) [ 345.832125] wlp0s20f3: send auth to $MAC (try 3/3) [ 346.803865] wlp0s20f3: aborting authentication with $MAC by local choice = (Reason: 3=3DDEAUTH_LEAVING) [ 350.389895] wlp0s20f3: authenticate with $AP_MAC (local address=3D$LOCAL_= MAC) [ 350.390412] wlp0s20f3: send auth to $AP_MAC (try 1/3) [ 350.396872] wlp0s20f3: authenticated [ 350.400017] wlp0s20f3: associate with $AP_MAC (try 1/3) [ 350.413168] wlp0s20f3: RX AssocResp from $AP_MAC (capab=3D0x1111 status= =3D0 aid=3D5) [ 350.414412] wlp0s20f3: associated [ 350.441020] wlp0s20f3: Limiting TX power to 36 (36 - 0) dBm as advertised= by $AP_MAC ``` Before finding this patchset, I also tried a few options from forums: Running plain mainline 7.3.0-rc6, disabling d3cold with udev rules, # disabling WiFi 7 options iwlwifi disable_11be=3D1 # Disabling Power Saving on BE200 wifi options iwlmld power_scheme=3D1 options iwlwifi power_save=3D0 uapsd_disable=3D1 Also tried connecting to a WiFi 2 only ssid (with "IOT friendly" options).
