Connection Problems on MBP

[Marinsky]

Hi guys, I am a new Macbook owner. I have been expieriencing problems connecting to wireless internet on my Macbook. In the top right corner, the WiFi image tells me that I am connected to my hone WiFi network, but when I try to use Safari, it tells me that I am not connected.
The Network Diagnostics does not help, after going through it step by step it tells me that it can not help me.
I thought about changing my default internet user from Safari to Chrome, but when i try to, it tells me that the only option is Safari...

Can someone help me please?

Ping a website domain name and check if the DNS server works in order. If not, you can manually configure the IP address, gateway and DNS, then try again.
