I've had no problem connecting to a variety of hotspots around the Wash., DC area except for "Free Public Wifi" sites. For example I was in a regional public library when my iPhone sniffed out and tried to connect to "Free Public Wifi". It never tells me it can not connect and in settings-wifi network-it will have a check mark by it and indicate I'm connected (no lock icon either) with excellent signal strength. BUT I'm not. iPhone shows (and never changes) Edge icon and it not on wifi. If I go to safari, pages load by Edge and no indicator of wifi of any sort. Any thoughts of what to try or do. I'm at a lost.
