Tommy,
Good morning.. I haven't taken the liberty of using foxfi yet but I know it seems to be the new standard in wireless tethering/sharing on devices over the last few months. PDANet I have used but only on my Nexus devices to setup drivers and aid in connection for rooting.
The best thing I can do is move this thread over to the General Help and How To forums where it will get more coverage and hopefully get an answer for your situation.
Good luck.
