Public wifi

Hello people! Months I have this problems and never got to fix it.
So on my working place there is a free public wifi. With any other device... tablet pc other phones, when I want to connect I'm just pressing connect and then the browser pops ups and showing me to press connect and then I have Internet. on my blackberry when I'm finding the network and pressing connect the browser is not poping up in order to do the connection. ( some public wifi poping up the browser in order to be able to connect to the network) any help?

no the browser doesn't pop up automatically most of the time. You need to go to the internet yourself and log in to the hotspot.
