Problem solved. I installed new drivers from DFI board CD and it didnt help. I called AOL again and this guy told me to go to control pannel and then go to System --> Hardware, and as it turned out, my comp wasn't detecting my DSL mdoem. I just had to right click it and update it and now it works fine. Thanks for all the help.
