ios 9.1 wifi password
I have an iPhone 6, using iOS 9.1
Often when I log onto a wifi network, the password dialog window does not show up. Example: at Detroit airport, there is a free wifi network. I join the network through Settings > Wi-Fi > and by selecting the network. The service is free, but you need to watch a video and select "accept and continue" on an internet page to connect. When I go to safari, I am unable to reach that page. This issue happens often in Starbucks and other public wifi networks.
Troubleshooting steps:
1) Tried opening a new page in Safari. It just hung there.
2) Closed Safari and reopened it. Same result.
3. Switched to airplane mode and then switched it off. iPhone automatically reconnected to the wi-fi network. I reopened Safari, same result.
Any easy way to solve this?
