I've got a rooted DX with the WiFi Tether app and want to thether my Asus Transformer to it. Wondering about some of the settings on the DX. First, exactly what needs to be active to tether: Background Data, WiFi, Bluetooth, etc. Secondly, there are settings that I have no clue about: eg-there are 11 channels to choose from, and 9 Lan-Network settings. How do I know which to choose? Also, should Access Control be on or off?
