Hi. I am having the same problem with my HTC Evo 3d and my Nexus 7 tablet. At work there is an open network that requires you to accept a policy before you can login. Both devices connect to the network without issue,but then never bring up the login page. Iphones don't have this issue and neither do some android 2.2 and 2.3 devices. My laptop does not have this issue. However both of my devices are having this issue. Under advanced setting for this open network there is a place where you can designate a proxy and designate a static ip but nothing else. Again its an OPEN network that will bring up a web based login. Please assist.
