There's something wrong with the Internet connection of my MacBook?

Question

It's quite strange, I think. For I use Airport Extreme to connect and there's nothing wrong with my Airpor, it always shows me that everything is all right. But my Safari just couldn't connect to the Internet properly.
I've met this problem for some times, but anyway it won't last for such a long time. It has been over 1 month this time.
Please help me.
Thanks~

Everything's all right, that's the problem~
Or I can say Airport is all right, but when I open Safari and it will tell me that my compter haven't connected to the Internet.
And my Safari is the newest version, my system is 10.4.10.

"But my Safari just couldn't connect to the Internet properly. "

Please tell us what DID happen, not what DIDN'T happen. What error messages did you get from Safari?

Call your Internet Service Provider, that's what they're there for.

If they can't fix this, call Apple tech support, they're Pros.
