As with other Android phones, my mini suffers with wifi issues. There is an "Advanced" options under wifi menu, which let you choose the wifi power profile. It does not make any difference for me what I choose. When I turn on the screen, the wifi is alway gone. I the check the wifi status and half the time I just says nothing. The other half of the time it says "failed connecting". To get the mini connect I the have to restart wifi, and everything is OK until the screen is turned off. I installed a "wifi fixer" from the Marked and managed to get the wifi running 24/7 after choosing "wifi performance". With this enabled the battery dried out after just 10-11 hours. Needless to say, this fix was removed after the next recharge. I have no idea if this is an Android 1.6 issue, but it seems like some X10 users are experiencing similar problems.
