Replying to Computer issue, don't know what to do.

Hey guys I'm having a issue with my computer (Samsung series 7 700z7c-s01). It won't connect to the Internet anymore. All my family members electronics are working (Toshiba laptop, MacBook, Xbox and iPad) and my phone is connected fine as well. When I try to get on the Internet it says "connecting" and will try to connect but always fail. I've tried updating my drivers, restarting and switching my Internet off. The only way I can get it to work is if I restart the router, but that fails after 15 minutes of being online. I can't find anything about this issue and really don't know how to fix this, hopefully you guys will know something.
