Please add the wifi module in generic-x86 image. 37141 1 nitin.a.kamble 2013-09-24 18:56:36 +0000 I added some kernel config options for broadcom wifi drivers into genericx86 BSP. that should resolve the issue. The fix is being sent to linux-yocto ML for review.

I tried to issue iwconfig wlan0 - iwconfig wlan10 and each time I obtained: No such device. I now that the wifi is turned on (using the button), but in terminal I cannot see any result. Also, lspci command returns the same result as in the bug description. 37579 5 nitin.a.kamble 2013-10-03 16:03:17 +0000 I do not have the h/w to test here. I have enabled all the broadcom wifi drivers in the kernel. Do you know what kernel driver is needed for this? 37582 6 nitin.a.kamble 2013-10-03 16:16:18 +0000 Do you see, this file on the target image? brcmfmac.ko Also check if it is getting loaded by command lsmod And check weather this command makes any difference? modprobe brcmfmac 37595 7 razvanx.ionescu 2013-10-04 06:33:41 +0000 Thanks for your info. The file exists. It is not loaded by default, but it is loaded after lsmod. But, the wifi still does not work as expected. No wlan0 or any other wifi interface name turns on.
