Yes, on the main thread page, at the bottom, you'll see a computer thread for tech questions.
It may not be a tech issue at all. My input is there are a number of open wireless signals at DXB so you have to chose the right one. When you go up the moving stairs from duty free, ask the INFORMATION desk.
From what I recall, once you connect to the hotspot, you then have to open browser to the hotspot default page (adverts) to fully connect to the internet - then you can go to whatever site you want afterward.
FWIW, the signal can be unreliable and often overloaded and worthless
I hang out in the Gulf Air lounge, they have a couple computers there if I really need it, otherwise I just let email dump into my blackberry.
