This is your problem. You need to figure why they're on a different subnet. There may be a setting in the Cisco router to split wired vs. wireless devices. What happens if you connect the Roku device to the Cisco router via Wi-Fi? The router could also isolate wireless devices by default and probably has a setting for that, so if they're both connected to Wi-Fi and still can't see each other look for that setting.
I can't connect the Roku to the router via WiFi because it needs a username and password login, rather than just the password, which the Roku doesn't seem to be able to do. I also can't check the settings on the router, as it's dorm WiFi and managed by the university.
A network that requires you to log in by entering a username and password into a web page via a web browser is the reason Roku developed its Hotel/Dorm Connect System.

I've checked that out, but that's not the problem I'm having. The username and password aren't being requested by a web page, they're being required to sign into the locked network, the same way just a password would be used with any other locked network. A screenshot of the page it shows me on my phone is enclosed
