Welcome to Android Central! I don't think Straight Talk allows tethering -- they want you to buy one of their mobile hotspots. See their Terms and Conditions:
"STRAIGHT TALK UNLIMITED PLANS CANNOT BE USED FOR: ANY APPLICATIONS THAT TETHER YOUR DEVICE TO A LAPTOP OR PERSONAL COMPUTER OTHER THAN FOR THE USE OF WIRELESS SYNC."
