I put this post :
Android 2.3 & 4.0 WiFi Internet HD 1080P HDMI Google TV Box ARM Cortex A9 Firmware
I don't know if you saw it or not
so if you can help us by just putting the old driver of wireless in the last test firmware 20120905_Android_ICS-ATV-108-f16ref-test.zip and try to let Ethernet work, or just put the driver of the external HDD in 20120625_Android_ICS-ATV-108-f16ref to stop dropping and disconnecting it from the last firmware, if you can do this it will be a GREAT HELP.
thank you again
