If your question is specific to 'tethering' your phone to your PC - to have Internet service on your PC - also called PAM (Phone As Modem) I'll try to help. I've done this before with my Samsung Jack - before I sold it.
Go into your phone's menu and look for the connection settings (by whatever name it is called - maybe "Internet Sharing"(?)). Make sure that USB is selected. (It's been a while since I've used the Samsung Studio software - so be patient with me and we'll work through this together.)
If I remember correctly, some Samsung phones also require the USB drivers to be downloaded onto the PC. (They may not be included with the PC Studio software.) And, the drivers were specific to the operating system of the PC. (ie., Windows 32 bit or 64 bit OS).
Without knowing who your cellular carrier is, I can't get more information from the Samsung Website...but you can: http://www.samsung.com/us/support/
Also, if you are using AT&T your Internet sharing program on your phone may be locked. If it is, you won't be able to choose MediaNet in your Internet Sharing program on your phone. This prevents you from 'tethering' with 3G /4G for faster Internet access.
If you need more assistance, send me a message by clicking on 'Comment' and I'll get back to you as soon as I can.
