Try to extract the follwing files from the original stock rom and copy them to your finless 2.1 rom (overwrite existing files):
/system/lib/libhardware_legacy.so
/system/lib/modules/wlan.ko,rkwifi.ko
/system/etc/firmware/WIFI_RAM_CODE
/system/etc/wifi/wpa_supplicant.conf
/ System / bin / Netd
/ System / bin / wpa_supplicant
/ System / bin / wpa_cli
Also set the permissions correctly (like they were before).
