I have a PC with internet connection. I want to use internet on my tablet via computer. How do I do this?
If you can make a "hotspot" from the computer/share connection which some computers have. Usually you need software to do that.
you can connect to internet from your TABLET via your router as suggested by Oron. You can also try connectify
There's a good discussion of this here: //www.makeuseof.com/answers/can-i-share-internet-from-my-windows-7-laptop-with-my-windows-phone-8/ . Also, just to mention the obvious, if you have a wireless router, you can connect to it directly from your tablet!
