iPad network log in problems

I just set up an MR60 Netgear mesh wifi network, which works wonderfully--great coverage, super fast, and easy to use. However, on my two iPads, the button to "Forget this network" does not appear. Also, when trying to log into wi-fi, when I click on the network I want to join, I am prompted for the network name to be typed in. In the past, the network name was auto filled and I was only prompted for the password. Finally, I am not able to log in to the network. I get an "Unable to join network" error message. My other devices including my two iPhones and my two MacBook Pros have no problems logging in to the network.
