Re: nexus 7 tablet will not connect to wifi at hospital! please help
I've had problems at my hospital with my Nexus 4 on Lollipop. I'd click on "log into network" and the little status bar incremented partway and hung and never popped up the actual login page so that I could accept the terms. My little wireless icon would have an exclamation point beside it. I've seen others complain of that too, at other institutions. I just kept retrying until I somehow got the login page and bookmarked it.
What I do now is every morning I click on log into network, and wait for the red lock. Then click on the 3 dots and choose the one that says use network anyhow. Then I go to the bookmarked login page where I can finally click on "accept". At that point it usually gives me a second prompt to log into the network, and when I do that, I get the network and get rid of the little exclamation points. It's a bit of a kludge, but at least it gets me logged in.
FWIW, on the same network, I've found that if I launch Firefox on my Windows tablet, it doesn't play nice with the hospital network and tells me there is no security and a bad certificate. But if I first launch IE (ugh), it gives me the accept conditions screen and is happy, and after that I can then use FF as well. (I know this is different than Android; just mentioning it because it may mean something to someone who can figure what the issue is).
