@BagOLobsters even if you had a remote to connect your Roku to the college network, the app still won't work. The reason is the WiFi network has a security setting that blocks connected devices from seeing other connected devices. On a public network like that, you really need that level of security, and the IT staff will not disable it for your use.
The Roku app on a phone or tablet will only connect to a Roku device if they are both connected to the same network, the network uses an IP address range within the private range, and there's no security function on the network that blocks connected devices from seeing other connected devices.
What model Roku device do you have? If it's any model other than a Roku Stick, you can buy an inexpensive universal IR remote from a wide variety of stores that sell remotes. But the Roku Stick doesn't support IR remotes at all, so for them you must have a genuine Roku remote.
