I had the same problem, using O2 wifi in Costa's Coffee Shops, which is a free service in most locations. However, I found that you have to register an account with O2 wifi (even though it's a free service - certainly in Costa's) and then, once registered, you need to register your device - up to 5 in total. Once your device has been registered to use the O2 wifi service, then you can surf the net without further problem.
It may well be that this process is good for all O2 wifi Hotspots - I can only speak re Costa's as it is one of my regular haunts :-)
Hope this is a help...
