I'm connected to my wifi and everything but I can't go on the internet why?

So on my Galaxy s6 updated to 7.0 (Nougat) for some reason I can't go on the internet or watch any sort of videos including ads. Also games that need wifi work perfectly fine. And I know for SURE its my phone and only my phone because everything else in my house work perfectly fine with not a single problem xbox, smart tvs, laptops etc. Someone please help me I don't know what to and yes I restarted my phone and forgot all of the wifi I have in my house its the phone's fault not the wifi.

Welcome to Android Central! It can still be a router problem even if only one device is having issues. Try rebooting the router by unplugging its power for about 30 seconds. If that doesn't help, see this guide for more tips: http://forums.androidcentral.com/amb...-problems.html
