Disable Wi-Fi @ Boot time Due to the Android Wi-Fi Driver issue, I like to disable the Wi-Fi during the boot time. Even if Wi-Fi is enabled in the setting, it should be disabled forcefully. User have to enable it after booting the device. Is there any specific property setting is available? If yes, how to disable during boot time?
If you've got root access and you're running a custom ROM you should be able to run scripts at boot time. Here is a thread on xda that discusses boot time scripts.

Then you'd just need to figure out the commands to disable wifi. On my Desire HD the wireless interface is called eth0. This command should disable wireless:

ifconfig eth0 down


Whether or not that will disable it permanently i.e. the system won't just do the equivalent of: 

ifconfig eth0 up


in the background, I do not know... I'm afraid I don't know much about how the android system handles networking, or at least not enough to help more directly with what to put in the the script!
