I have a user that can access the internet fine through his wireless connection on his laptop from within the office but can not access from outside the office. His laptop shows that he has a strong wireless connection. I had him check to ensure the wireless access at the latest airport he was in was free and he stated yes. I checked his proxy server settings and they are fine (ie not using a proxy server) I checked the internet security level and it was at medium. I even had him set it to low just to see if he could reach google.com. Still no luck. I had him try through windows explorer and no access. He keeps getting the message "Page can not be displayed." THis last time he was asked to accept a certificate from the airport free wireless. What could be causing this issue that he is not able to surf the internet. He has tried to access many different pages and always gets the same message.
