hi i am having a problem with my gateway laptop. i just recently paid a technician to repair my laptop. he put in a brand new hard drive and reinstalled the windows 7 software and ever since he did that my internet does not work. it sayd the default gateway is not available and the dns server is not rsponding so i took it back to the technician and he said it has nothing to do what he did and that he installed everything so i called comcast and they came out to check. connection is perfect and they even gave me a new modem. i'm still having the same problem. comcast is saying it's not them and the computer must be missing some hardware and my technician is saying it's not him...help!!!
