Also try pinging a website instead of going through firefox.The problem with the Internet as it is is that when I try to open firefox in backtrack 4, the browser says it cannot establish an internet connection. I'm trying to figure out why it's saying that, and more importantly, how do I fix this? If someone can help me out here, I thank you ahead of time, and again later
once you believe you are connected then try something like
ping -c 4 www.somewebsite.com
If packets return then you know that you have a connection (at least to where you pinged).
Also since it is vmware make sure that your vmware can access the internet itself.
