i installed linux a couple of days ago and i m having a problem with the web browsers.

i have broadband but when i try to access a web page the browsers do nothing for some secs(up to 30) and then downloads the page. i tried all 3 browsers of my distro(mandrake 10) and it happened in all of them.

i ran the monitor connections utility and found out that when connecting to a web page the browsers stay on 0 kbps for some secs and then transfer quickly for half a second.
anyone knows how to fix the problem or where to search for a solution?
thanxs in advance.
