IPhone and iPad won't connect to public Wi-Fi?

I just downloaded iOS 6 and now neither my iPhone or iPad will connect to Wi-Fi. I select my no password needed Wi-Fi router under Wi-Fi settings and a login page through apple pops up and says page not found. Hoe do I get connected?

I just did the same thing and am having the same problem with the login page popping up. I'm hoping someone can answer this too!

I along with you and many others are having this issue. After doing a hard reset on my phones and ipad, resetting network settings etc and no fix I did the following and for some reason it worked. I plugged the devices into the cord, one on the wall charger, the other to a computer (without iTunes running) and then went back to the Wi-Fi and selected the network and it connected and has been fine since. I have no explanation for this. Almost like you had to jump start the darn thing.
