My 2015 Macbook Pro will not connect to the Internet. Every other unit in the house has internet access except Macbook Pro. Internet for my macbook works at school? (which is strange), but it does not work while at home. It shows that I'm connected to a Wi-Fi signal as it shows the 4 white bars, but when you enter an address on the safari, nothing comes up (it says that safari can't open the page because safari can't establish a safe connection to the server. tried to reset my internet, restarted my Mac, renew the DHCP license. All in all.
I've had this portability for almost two years now, with no problems at all. on Sunday 5/19/19.
edit: I should have mentioned that I used a VPN when this problem had begun to occur, Vpn had stopped working so well at home, but it works at school, even though I had used this home for a few weeks without the problem at school and at home.
