New Install XP Pro can’t get internet

I recently installed XP Pro on a Dell computer, everything loaded fine . I have cable (Roadrunner) and after setting up computer I can’t get on the net. I click on Network conections Lan /High Speed and status it shows activity in and out showing sent and received. But I can’t get on when I click on internet explorer, can’t log on. The I check and do have the firewall off so that’s not the issue. I just download winsock repair on my other computer to see if that get it to work but not sure what is going on any ideas. Thanks
