Getting internet for Galaxy Tab 2 from Galaxy S3 Is there a way to use the Galaxy Tab 2 with my Galaxy S3 (SPRINT) to get an internet connection?
Yes, very easily actually.

To Make your S3 emit a WiFi network


Enable 'WiFi Tethering' in System Settings-&gt;More-&gt;Tethering and Portable Hotspot-&gt;Portable WiFi Hotspot. 
Configure the hotspot (name, password etc), in the Setup WiFi Hotspot menu.


To Connect your Tablet to the WiFi network


Enter the tablets WiFi settings, and turn WiFi on.
Select the WiFi network you configured on your S3).
Select connect. If you setup a password, you need to enter it.


Other Info

If you do not see the WiFi Hotspot option, then your network has disabled it. If you're rooted you could use an app such as WiFi Tethering - just be aware that this will produce an Ad-Hoc hotspot, and Stock Android cannot connect to these types of hostspots.

There is currently no way, AFAIK, to create a standard WiFi hotspot without using the stock android tethering system.
