I have a Spark7162 receiver with one tuner called Truman with hardware based on SH4.

I installed the latest Enigma2 image from here "http://www.hdmedia-universe.com/board/pages.php?pageid=1&box=spark7162". Although I can connect to the network using cable connection I am unable to connect using WIFI. The attached USB WIFI stick is based on Controller RT5370. It works perfectly under Spark but not Enigma2. Under the System menu I can only find Network setup but no WLAN. Please provide necessary instructions on where to download the suitable IPK that works with this image and how to install it.
