I guess you have tried playing with settings for the Wi-fi Switch.

It sounds similar to the issue where ActiveSync keeps trying to sync every time the clock changes.

In the Notification Queue, I delete the replog.exe (with MemMaid, you could get a free trial) that is described as "Argument: AppRunAfterClockChange" or something like that, and there may be one for your issue, too.
