Did you disable runtime-pm for the mmc host controller with bcm43241 device. From your log I see the driver tells the firmware to join "BRAINNET 1" but wpa_supplicant times out after 10 seconds. I suspect the host controller went in runtime suspend so the connect events from the firmware are not processed until wpa_supplicant gives up and host initiates interaction with the device. The controller should be somewhere under /sys/bus/acpi/drivers/sdhci-acpi/. If you have the correct controller there is a power subfolder. Check the control file: $ cat control If it says auto, change it to 'on': echo 'on' > control When done, load brcmfmac.
