there are other devices, a laptop and and iphone. both connect with no problems. the ipad was connecting ok up to yesterday. have tried all the switching off, disconnecting, switching on, reconnecting. it is not the password that is the problem. the password is caps, and have tried in it both caps locked and caps shift. neither work. in any case, if the password is incorrect, it usually says that, in this case it says unable to join the network. when you click on the little blue button next to the network name at the top of that page it says join network. all the ip address details are missing. at the bottom of the page should evidently be a button which says renew lease, this is missing. I have downloaded all of the updates, no difference. after downloading the updates I have retried rebooting, resetting all the settings, resetting all the network settings. nothing.
