Can't connect to facebook but internet is working

Sometimes I can't connect only to Facebook using safari or chrome, (can't find server), internet is working, but if I change DNS server from 192.168.0.1 to 8.8.8.8 and 8.8.1.1 everything works great... Can someone tell what is problem?

is 128.168.0.1 the IP address of your Router? Or ISP DNS? Or…?
Using Google DNS all works so it is a DNS problem.

Thanx for answering, 192.168.0.1 its my Router IP address, and everything works fine when I change DNS in MacBooks WiFi settings from 192.168.0.1 to 8.8.8.8/8.8.4.4, its not a big problem but I just want to know the reason...

Ok, the problem is that your router has a DNS cache but it is not working well.
Some possible solutions:

1. Update the firmware of your router with the last version available and check if the problem is solved.
2. Upgrade your router with a new one.
3. Change the DNS in all Clients ( like you did ).
4. Setup your router to send Google or Opendns or Clouflare DNS IP to all DHCP Clients.
