Not able to connect to DB(Deutsche Bahn) Wifi on ICE trains using Macbook Pro?

Troubleshoot WIFIONICE MACBOOK (wifi on ice)

  • Disconnect wifi
  • sudo killall -HUP mDNSResponder
  • go to System Preferences > Network > (Select) Wifi > Advanced > DNS to add a sample dns 8.8.8.8
  • Connect wifi And go back clear the DNS added.
  • Reload the http://wifionice.de/de/ website and start surfing.

(This method works for me consistently)
