The Notebook Review forums were hosted by TechTarget, who shut down them down on January 31, 2022. This static read-only archive was pulled by NBR forum users between January 20 and January 31, 2022, in an effort to make sure that the valuable technical information that had been posted on the forums is preserved. For current discussions, many NBR forum users moved over to NotebookTalk.net after the shutdown.
Dell is using the toshiba stack. I believe the toshiba stack doesn't support this. You need the widcomm stack to do this. But since dell didn't not license widcomm stack for use with the bt 350, so it's illegal to install widcomm stack with dell 350 hardware.
