If you have the fortune to need to follow some silly “Login” button for some wifi, regularly, the following little script may help you avoid this idiotic (and useless) task.

This example uses the WIFIonICE, the free wifi on german ICE trains, simply as I have it twice a day, and got annoyed by the pointless Login button. A friend pointed me at just wget-ting the login page, so I made Network-Manager do this for me. Should work for anything similar that doesn’t need some elaborate webform filled out.
