Quick guide on using the Eduroam university internet on Linux

I've had some troubles trying to get the Eduroam network working on my laptop when I'm at my university, which is not preferable as their guest wifi kinda sucks. But I finally fixed it and got it working perfectly*. I'm hoping this will help someone, somewhere.

My university (and others?) distributes a simple shell script that has us sign in to our uni login page and then configures the eduroam internet settings accordingly to allow us to sign in. The problem: the script barely works and the website just throws an error after you sign in. And sometimes when I try to connect it just says "No secrets were provided" and there was another error about wpa_supplicant that I don't remember.

So I had to figure out how to configure it manually, which is actually pretty simple, you just need to set the following options in your network settings. I set the security to "WPA/WPA2 Enterprise". Authentication to "Tunneled TLS (TTLS)". Inner authentication to "PAP". And put my university email as the username (ie. guynamedzero@university.edu), and my universities password as the password. And boom! It just started working all of a sudden, no CA certificate was required either. Now, I'm using KDE plasma, so things might be slightly different if you're on gnome, but they probably have all this as well (citation needed). I imagine this won't work for every uni, but it wouldn't hurt to try if you're having similar issues to me :)

Sometimes Eduroam just closes my connection to the internet. I have no idea why it does this, but it gives no errors, no popups, nothing. I can just no longer access anything on the internet until I disconnect and reconnect to the wifi. It's infrequent enough that I'm not too concerned about it, but YMMV.
