Laptop recognizing and connecting to Galaxy S4 hotspot, but not working

view story

http://forums.androidcentral.com – My laptop (operating on windows xp) used to work fine with my Galaxy but now that I've upgraded to the Galaxy 4 my computer will recognize the hotspot, say it's connected, but the internet will not work. I've tried tethering but it can not recognize the driver. Any suggestions? Thanks! (HowTos)
