I an new to Wireshark.
I folowed [this](https://opensourceforu.com/2017/10/visualising-response-time-web-server-using-wireshark/) tutorial which simply pings www.wikipedia.org and captures packets using Wireshark.
As per this tutorials, wireshark captures http packets.
But, for some reasons it not showing packets under http protocol, instead I have TLSv1.2 packets. 
Note: I also have promiscuous mode on.
I need to see http packets so as to view the request and response.
