Comodo Firewall blocking access to my unviersity internet

So I have been trying to connect to the wireless internet at my university, but the firewall keeps blocking the internet connection. Originally, it was recognizing it and it came up as a new network zone, but I forgot to tick off the box that let the connection access anything. Since then, I have tried to delete the zone, delete the connection itself on Windows, and I’ve tried using other connections here, but it will not detect the new network and let me tick off that box.

What can I do in order to use the internet without having to disable my firewall each time?

-Windows 7 SP1
-Comodo V5.5.195786.1383

Try disabling Block fragmented IP Datagrams .
