BleepingComputer.com: "Page cannot be displayed" despite good connection

Dear All,
I have my computer hooked up to the internet via a wired ethernet connection. My computer says that the connection is "excellent" but then the internet cannot display webpages, both Mozilla and Internet Explorer. I have tried messing with the settings (in internet options) but none of them are working.

I tried detect settings automatically, no proxy, automatic proxy.

I also don't know what a poxy is, so it says I have to type one in, but I don't know how to do that.

It's so frustrating, because it has nothing to do with the connnection, the connection is great.

Thanks in advance.

Have you tried several webpages, becouse sometimes its just the sites servers that are slow.

yes. it won't display any web pages. Something with the settings is not right, i just don't know a lot about settings.

isnt there a button, or way u can go to the default settings? That generally is possible

Is this a new internet connection you are setting up? or an established internet connection you've been using and now suddenly does not connect?

In firefox, go tools>options>advanced>network (its a tab)>settings and click no proxy.

Or try downloading safari or opera or use IE and try to connect with them cos it might be firefox and not ur connection.
