Thanks for your bug report. Can you try to reproduce this bug with Intrepid Ibex final release with all updates? When OK button is greyed out, it normally means that you forgot something. You should make sure that the "Address, netmask, gateway and dns" fields contains correct values. If the problem is still reproducible after installing final intrepid release, can you also post exactly what you typed in each fields?
