Streamyx New DNS Server

When i reconfigured my Streamyx connection, i do a DNS setting. For the reason my connection seem not stable like before. I try to find what caused this.

After some tweaks,i set to get DNS from "WAN Interface" mean auto from ISP.. What the new thing is my ISP give me primary DNS server 1.9.1.9 and secondary DNS server 202.188.0.133
