inforce6410plus, ubuntu, wlan problem

I installed linaro ubuntu from https://releases.linaro.org/ ubuntu/boards/snapdragon/latest/ on my board, Inforce6410PLUS by the following commands.I did not install anything else on the board:

sudo fastboot flash boot boot-qcom-apq8064-ifc6410-qcom-snapdragon-20151026-139.img sudo fastboot flash cache firmware-qcom-snapdragon-20151026-139.img sudo fastboot flash -S 768M userdata linaro-vivid-developer-qcom-snapdragon-20151026-139.img

the problem is that linux does not show Ethernet or wlan0 as the output of ifconfig. I did "modprobe -r ath6kl_sdio" then "modprobe ath6kl_sdio" but nothing changed.

How can I solve the problem?
