Tried wifi in France. Worked fine at free sites like mcdonalds, but not at hyatt without serious intervention

Somehow their provider doesn't allow one to go past the signin page once the managers contacted their provider and they requested the Mac address of my iPad and they did something on their end then it worked without signin

Accor same problem. Never resolved.

FYI
