how to force the network captive page to show up again

Question

I got into a hotel that has two wifi options: standard and premium. the first time i connected to the hotel wifi (on mac) it showed me the default captive page. I went with the free one.

However I later on purchased the premium card.. but now I have no idea how to make that captive page show up again since it simply re-logs using the free account. Any idea how I can force it to show the captive page again? I already erased cache etc of chrome/safari.. no luck

update

so the network is called citymax.. i found this in

/Library/Preferences/SystemConfiguration/com.apple.airport.preferences.plist 

    <key>wifi.ssid.&lt;43495459 4d4158&gt;</key>

        <true/>
        <key>TemporarilyDisabled</key>
        <false/>
    </dict>

i tried playing around with those values (even deleting the entire key) but no luck.. any ideas?

Solution

First thing I would attempt would be to try going to the url of the default gateway.

If that does not work you will probably have to change your mac address. Most systems go off the network adapter's mac address.
