MT7628 WiFi does not work

Hi guys
I have a MT7628NN based module with 32Mb DDR/ 16Mb flash memories, and also 1 Ethernet and 1 USB ports. I made a squashfs-sysupgrade.bin using OpenWrt-ImageBuilder-15.05.1, using Tftp, PuTTy and following packages:

make image PROFILE=Default PACKAGES="luci-base luci-mod-admin-full luci-theme-bootstrap base-files busybox dnsmasq dropbear opkg swconfig uci wpad-mini luci-app-mjpg-streamer uhttpd kmod-mt76 kmod-video-uvc kmod-mac80211"

I could get the Openwrt banner and also log in to the Luci but I cannot turn the wifi on. Also there is no etc/config/wifi file. When I run wifi detect > /etc/config/wireless, the wifi file will add to etc/config but there is no configuration inside it. Also I filled it as follows but no change:

config wifi-device 'radio0'
      option type 'mac80211'
      option macaddr '[redacted]'
      option ifname 'test'
      option hwmode '11a'
      option channel 'auto'
      option country 'US'
      option htmode 'VHT40'

config wifi-iface
      option device 'radio0'
     option mode 'ap'
     option ssid 'openwrt'
     option encryption 'none'
      option network 'lan'

Here also is the output of echo $(opkg list_installed | awk '{ print $1 }'):

root@OpenWrt:/# echo $(opkg list_installed | awk '{ print $1 }')

May I have your helps for solving the wifi problem?
Thank you in advance
