My mistake. I should have clarified. my actual internet type is wireless. The antenna on top of my house is connected to a wireless lan router (nl-2611cb3 plus by netgate) via ethernet. find hardware at www.netgate.com/product_info.php?products_id=31
Because my isp is gay, i have to use a network hub to share internet connection with the xbox in my room. I was suspicious that the hub was firewalling, so i bypassed it and wired the computer directly into my netgate box. this didn't seem to make a difference. keep getting message "computer doesn't seem to be connected to internet."

Hope i made things clearer!!!!!!!!!!!!!!
