Internet connectivity issues

Ever since I started using Comodo, it cannot connect to the school internet.
It has no problems with the home network, but the school connection seems to be an issue.
It connects to the network, however the additional login screen to connect using the school portal won’t show up and I think it’s because the firewall is blocking it.

How do I change the settings to allow the network to connect properly?

Welcome to the forum.

You could try selecting ‘Training Mode’ from firewall Settings. Just enable it for the duration of the connection to the school portal and then turn it off. If that fails to help, you’ll need to provide us with some additional details regarding the network and your CIS settings.
