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

[Android Central Question]

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.
