logging into public wifi

[kc2ky]

I am looking to connect to my public library's wifi or via optimum wifi with a raspberry pi and a USB wifi dongle. In both cases I am required to push an "I agree" button on the web browser. In the case of optimum wifi, I am required to enter a username and password.

I've already succeeded in connecting to my wireless access point at home, where the SSID and WPA pass phrase are known.

When in a public wifi spot like a library or when in range of an optimumwifi hotspot, on a Windows PC running IE or firefox, I get redirected to a web page where I get a prompt for a username/password, or in the public library case, just an "I Agree" button.

Not so with the Raspberry Pi. Can anyone give me some insight as to how to get to the appropriate login page with the PI?

Thanks in advance

For a lot of those systems opening a web browser and heading for http://google.com causes them to redirect to their login/authentication page.

The one time I had trouble was on site at a customer with my IBM RedHat Linux laptop and the redirect/login/auth stuff was all written to work with Windows only. That's when it gets complex and you end up having to read the HTML to work out how to navigate past it.

Our local libraries have been having issues with their WiFi systems for the last couple of weeks. You can connect to the access point, but the login screen doesn't appear when you use a browser and you can't access the internet.

Apparently this is because a software upgrade is needed on the library system and is being rolled out across the county.

I don't know where the OP is, but wonder if their library system is being hit by the same problem.
