We are in a hotel which provides free wifi. The hotel gave us their wifi password. My friend has an ipad 2 with ios7 and when he tried connecting to the wifi network, he was prompted for just a password. He put in the password and it worked. I have an ipad air and when I try connecting to the same network, I am prompted for a username AND password. I don't know what's the username (??? what is that? my friend doesnt need to enter a username) so I left it blank. And i put in the password. Then I get an error that I am unable to connect to the network. Can someone help?
