Trouble with Internet

Want to connect to internet but having problem just now.
My DSL light is stable. Its just that I cant connect to the net.
After spending almost an hour with the support from TM doing this and that.
Finally found out the problem....

My DNS server. Should put it to streamyx's DNS.
The DNS are:
202.188.0.133
202.188.1.5

Before that I have to flush DNS.
The command is ipconfig /flushdns

Actually I have been using OpenDNS for quite some time without much problem.
Maybe its because of the undersea cable near Egypt. I don't know.
Later maybe I'll change again.
