Windows 8 wifi browser based login

OK having the problem of the wifi connection not getting to the browser username/password log in screen.

i'm at uni. the free wifi uses wpa2-psk. click connect enter a password after logging you onto the network it should open a browser window for me to enter a username/password before giving me access.

problem been that the window wont open. the network sits a the "verifying settings" status

i read some ware that if you set up the connection manually, you untick the "connect automatically" box and it will allow you into a security tab that gives you a few more options like PEAP.

but i have no way of removing a wireless connection so i can recreate it manually.

I am running Microsoft Windows 8 Enterprise 6.2.9200 N/A Build 9200.
i have heard that uninstalling your wireless card removes all wireless profiles and will allow me to do this. but i had that many problems with getting my wireless card to be stable in the first place i would really love it if there was another way.
Thanking you in advance for you time.

VERY frustrating! Works perfectly on Win 7.
