How do i know if my internet is live
 

How do i know if my internet is live. I am having that port problem and i dont know how to tell if my internet is live?

try pinging...
 

you could always shell to dos and try pinging hosts... first try your gateway... which will be your exact IP but the the last group of digits will be 254:

ie:

Your IP: 192.168.1.110
Your Gateway: 192.168.1.254

if you can't ping your gateway then it means you don't have a prayer of making a connection to the net...

if you can then ping yahoo.com or google.com or somthing like that.... the syntax is as follows incase you've never done this before:

at the c:\> type: "ping 192.168.1.254" or "ping google.com"

if it comes back with times then you are connected if it comes back as "Host Unreachable" then you have problems...
