Visiting a friend with a secure wifi network. I have the password and have used the wifi on my Iphone & iIpad many times. On this visit both of my devices showed I was connnected to network but I could not get online. Their daughter was also visiting, she has an android phone, and she had the same problem, but the homeowner was able to get online even though we couldn't. He said he had not made any changes recently or had any problems so we are perplexed. Especially since it happened to two of us with different types of devices. Any help appreciated.
