I have a 4s with ios6. I know there were earlier Wifi issues and lots of complaints on the first day of iso 6 release but Apple "resolved it" by fixing their website. However, I am still experiencing an issue which I think is related to having a limited "data plan" with my carrier Speakout and a authenticated hotspot. The "data plan" only allows port 80 and 443, so works for browsing and most apps. Of course some features won't work on 3G which I can live with. My work place has a Wifi hotspot that required you to authenticate to access (an extra step of security). While still on ios 5.1.1, I can walk into workplace, fire up a browser and be redirected to login page to authenticate and then I am connected via wifi. After ios 6 upgrade, Wifi is not connecting. When I manually try to connect, it will try to get to the login page automatically and fail with the error " Hotspot login cannot open the page because it could not establish a secure connection to the server". Tried resetting, forgetting networks, etc, but could not work. However I found a TEMPORARY FIX: Turn off 3G first, connect wifi, authenticate and login and then re-enable 3G. I think when attempting to connect to authenticated wifi with 3G on, ios 6 tries to send something via Speakout's 3G on a unsupported port (not 80 or 443) and fails, and then it gives up and refuses to connect to the wifi authenticated login page. So an extra step for me. Anyone else experience the same issue?
