After fastboot boot image, WiFi cannot work

Firstly I Downloaded the followed images and wrote it to RB5-96boards.
[Linaro Releases]
1> boot-linaro-sid-qrb5165-rb5-146.img.gz
2> linaro-sid-gnome-qrb5165-rb5-146.img.gz

WiFi can work well. wl1ps0 device will show by ifconfig.

Secondly Compiled the kernel according to the Release Note[Linaro Releases]

After that, fastboot the boot-rb5.img, delete the origin modules[rootfs/lib/modules] and copy the compiled modules to [rootfs/lib/modules], reboot the board.

After reboot the board. I cannot see the wlp1s0 device by ifconfig.

what do I went wrong? Please help check that.
