To be honest, I don't follow this exactly as I've been lightly scanning this thread.  I have a T42 with built in wireless. (168C:1014) and have SpeedStep Enabled in bios and I DON'T have a problem connecting (etc) running on battery or AC.  My power mode for Battery is [Maximum Battery Life] and customize [Fixed Max] [5 minutes] [5 minutes] [3 minutes] for those fields.  Mode for AC [Automatic] and mode for battery [battery optimized].  Many other fields are enabled too....  Is the problem only with certain wireless cards (such as the Toshiba branded Mini_PCI card) or supposedly in general?

Hi Al,

  The findings and instructions are ONLY based on experiences with the Intel 2200BG based MINI-PCI Wifi cards. (including IBM, Toshiba, Dell and others), so may not apply to yours.
