Traveling on the train – wifi works fine on my iPhone but not on my laptop.

Windows 10 detects the irish-rail hotspot, connects but won’t load up the captive portal; http://irishrail.on.icomera.com/ – Pinging the gateway yields a reply. [ 10.101.0.1 ]

A quick ping of irishrail.on.icomera.com:

Ping request could not find host irishrail.on.icomera.com.  Please check the name and try again.

Followed by ipconfig /all – yep, using Google’s DNS servers [ 8.8.8.8 ]

Quickest fix is to set your DNS to automatic when using the irish-rail hotspot or add the following to your host file:

10.101.0.1 irishrail.on.icomera.com
